Best Harley-Davidson Tool Kit: SAE, Metric, Torx and What You Actually Need

Contents: combination wrenches 3/8, 7/16, 1/2, 9/16 in and 10 mm. 1/4 in drive ratchet with 2 in extension and matching sockets. Hex keys 1/8 to 5/16 in. Star keys T25, T27, T40. 5/8 in spark plug socket, 8 in adjustable wrench, locking pliers, tyre gauge, duct tape, cable ties, mechanics wire, threadlocker.

The default answer, and the kit Google's own AI summary names first when you ask this question. 868 ratings at 4.8 stars, no one or two star reviews at all in the histogram.

What makes it the reference is that the contents match the actual Harley size list rather than a generic motorcycle one: four SAE combination wrenches for the chassis, one 10 mm for the metric outliers, and Torx T25, T27 and T40 which are the three that come up most.

The reviews are full of the jobs it was bought for. The best of them: "This tool set is a lifesaver, shifter linkage came undone and this awesome tool set got me right back on the road within 5-10 minutes." And on the format: "It rolls up compactly and takes up very little space in the saddle bag compared to other options."

Be clear about what you are buying, because owners are. This is emergency-grade steel, not shop-grade. One puts it well: "It's a good kit for what is, which is something to help get you off the side of the road. It's not Snap-On or Matco quality but it's compact." Another, less charitably: "All the hype I expected higher quality tools." Amazon's own summary records the split directly.

At $118 that is the honest tension. You are paying a premium for the curation and the roll rather than for the tools.

Two gaps in the contents. Torx stops at T25, T27 and T40, so T20, T30 and T45 are not covered. And several owners across the CruzTOOLS range ask for a longer hex key, because the short ones will not reach past a cover.

What owners say: “This tool set is a lifesaver, shifter linkage came undone and this awesome tool set got me right back on the road within 5-10 minutes. - Mad Mellow”

Contents: 14 x 17 mm open end, 12 mm and 10 mm combination, 8 mm nut driver, combined 5/8 in and 18 mm spark plug wrench with lever, 5-in-1 screwdriver with Torx T20, T25, T27, T30 bits, hex keys 3, 4, 5, 6 mm, 0-20 psi tyre gauge, locking pliers. Developed for all Harley models EXCEPT the V-Rod.

The pouch that actually stays on the bike. Roughly the size of a can of spray paint, it goes under a seat or in a fork bag rather than eating saddlebag space, and that is the whole argument for it.

An owner: "Pretty nifty little tool kit. Everything fits inside the zippered bag, and the bag is maybe the size of a can of spray paint." Another used it immediately: "I used it within minutes of receiving this kit to perform some maintenance on my 2016 H-D Sportster Forty-Eight. Worked great and had everything I needed."

Now the finding that makes this kit interesting beyond its size, and which you should understand before you buy it. It contains no SAE wrenches at all. The wrench set is 8, 10, 12, 14 and 17 mm, and the description says it covers "most common metric fasteners."

The same manufacturer's larger RoadTech H3 is built around SAE. So CruzTOOLS reached opposite conclusions about which standard a Harley uses, in two products sold side by side. The reading is that newer bikes are more metric. If yours is older, or if you are unsure, the SAE-based roll is the safer buy and this is the supplement.

The 0-20 psi tyre gauge is a genuinely good detail, because a 0-150 psi gauge cannot resolve motorcycle pressures well.

Limits owners name: the pouch is too tight to add anything to, there is no 3/8 drive ratchet so anything needing leverage falls to the locking pliers, and one owner is honest about the steel: "Not sure how good the tools are. It's better than no tools."

What owners say: “I used it within minutes of receiving this kit to perform some maintenance on my 2016 H-D Sportster Forty-Eight. Worked great and had everything I needed. This is permanently in my bag now. - Ron Brown”

Contents: 3/8 in ratchet driver, 5/8 and 13/16 in spark plug sockets, open end wrenches 3/8 and 7/16, 1/2 and 9/16, 5/8 and 3/4 in, 10 mm combination, 9 hex keys, 7-piece Torx set T-10 through T-40, four screwdrivers, locking pliers, tyre gauge, spare bulb, siphon hose, mechanics wire, electrical wire and tape.

The widest Torx coverage of any roadside roll here, and roughly $30 less than the CruzTOOLS kit. If the Torx section of this guide worried you, this is the kit that answers it: a full seven-piece set from T10 to T40 rather than three keys.

It also carries six SAE open end sizes up to 3/4 inch and a 3/8 inch drive ratchet rather than a 1/4 inch mini, which means real leverage on bigger fasteners.

An owner who compared the two directly: "I selected the Windzone over the Cruz kit because it has more tools at 30 bucks less than the comparable Cruz kit." He is also honest about what that buys: "this is a pretty good emergency kit, but the quality of the tools is mediocre. I'm OK with that because they will do the job if needed."

That is the right way to think about a roadside kit, and it is the same conclusion the CruzTOOLS owners reach at a higher price.

Three things to fix on arrival. The bundled multi-tool is the item owners single out: "The multi tool is very, very tiny and cheap and is basically useless." The siphon hose is too short to actually siphon between two tanks. And Amazon's review summary records "issues with the ratchet wrench failing after first use", with one owner simply saying "I did change the ratchet."

Also note some tool sleeves in the roll are open at the bottom, so tools can work their way out in a saddlebag. Check it after the first long ride.

What owners say: “I agree with many of the other reviewers in that this is a pretty good emergency kit, but the quality of the tools is mediocre. I'm OK with that because they will do the job if needed. - BrewCityRider”

Contents: open end wrenches 1/2 and 9/16, 3/8 and 7/16, 5/8 and 3/4 in, 10 mm combination, 6 in adjustable, 3/8 in drive ratchet, two spark plug sockets (5/8 and 13/16 in), locking pliers, 10-piece hex key set, tyre gauge, flashlight, electrical wire, mechanics wire, tape, five cable ties.

Strong on SAE, generous on hex keys, and it contains absolutely no Torx. That is not an oversight in this write-up, it is the product, and it is why the most useful review on the listing is a five-star one that ends with an instruction.

"It fits well in the saddlebag and has all the tools you need for an emergency or even to address a casual update. Just add a torx 25 and 27. Your done."

Take that literally. Two Torx keys cost a few dollars and turn this from an incomplete kit into a complete one.

What it does well is SAE coverage and leverage. Six open end sizes up to 3/4 inch in three double-ended wrenches, a proper 3/8 inch drive ratchet, two spark plug sockets covering both older and newer Harley plugs, and a ten-piece hex set which is more than most rolls carry.

The roadside save on this listing is a good one: an owner whose fuel-injected bike was "gushing gas onto the ground" because a hose clamp had worked loose over the years. "So I got out my trusty Biker's Choice Tool Kit and reinstalled and tightened the hose clamp up, then was on my way back home."

The complaints are consistent and small. The bundled flashlight arrives broken often enough to be a pattern, and it is the item people replace first. The hex keys are loose in a bag rather than held in a holder. The roll closes with two strings rather than velcro. And one one-star review says what several four-star ones imply: "Way too much money for what it was."

What owners say: “It fits well in the saddlebag and has all the tools you need for an emergency or even to address a casual update. Just add a torx 25 and 27. Your done. - MJ”

Contents identical to the RTH3: combination wrenches 3/8, 7/16, 1/2, 9/16 in and 10 mm, mini 1/4 in ratchet with extension and sockets, hex keys 1/8 to 5/16 in, star keys T25, T27, T40, 6-in-1 screwdriver, 5/8 in spark plug socket. Shaped to fit the teardrop box on a Softail.

The same contents as the RoadTech H3 in a flat zip pouch rather than a roll, shaped to drop into the teardrop tool box on a Softail. If your bike has that box, this is the closest thing on the market to a modern factory under-seat kit.

An owner with a Heritage Softail Classic: "Very pleased with all of the tools that came with the pouch, which by the way fits beautifully inside the Harley Davidson Tool Box installed on my Harley Davidson Heritage Softail Classic."

The best review here is a story that makes the case for owning any kit at all: "The same day it arrived, I was 2 hours from home when the battery gave out. So while I waited on a battery to be delivered by a friend, I used this kit to remove the battery."

That same owner, with forty years of riding behind him, gives the definitive additions list: "wire strippers, needle nose pliers with side cutters." Those two items come up more than anything else in this whole category.

Check the fit before you commit. Not every teardrop box takes it easily: "It's a pretty decent tool kit BUT it doesn't really fit inside my tear drop tool box, I mean it does but I really have to force it in there."

Three other niggles from owners. The spark plug socket wants a different drive size than the supplied ratchet, so throw an adapter in. The hex keys are short - "you should add longer Allen wrench with the shorter ones" from an owner whose gear shifter came off 300 miles from home. And the bundled WD-40 is a single-use sealed pouch.

What owners say: “The same day it arrived, I was 2 hours from home when the battery gave out. So while I waited on a battery to be delivered by a friend, I used this kit to remove the battery. - G. K. Wallace”

Universal. NO TOOLS INCLUDED. For riders building their own kit from tools they already trust. Elastic loops in a range of widths, plus a separate zip pouch for fuses, hardware and patches.

The honest option if you have read the quality complaints on every pre-filled kit in this section and concluded you would rather carry tools you already trust.

Twenty-six dollars for a 1000D Cordura roll with three flaps, two velcro straps and elastic loops in varied widths. MOLLE webbing on the outside so it straps to a rack or luggage instead of sliding around loose in a saddlebag, and a separate zip pouch for fuses, small hardware and patches.

Two seasons of real service from one owner: "I've had the Odinsberg tool roll on my bike for 2 riding seasons now. It has held up well and I've had the unfortunate need to use it on at least 2-3 occasions. Having a socket set, screwdriver and zip ties was enough."

Another on what it holds: "It is just the right size to hold all my general tools and extras for general motorcycle trips. Sockets, wrenches, tire pliers, patches, fuses."

The hard constraint is length. Maximum tool length is 8.5 inches, which rules out full-length combination wrenches and any 1/2 inch drive breaker bar. Plan the kit around that number before you buy, not after.

The other honest note is loading. An owner: "The only complaint is the way you have to feed long items through an elastic loop inside. I'd rather have one fewer straps to have the room to get them in when in a hurry on the side of the road." A roll you cannot repack quickly at night in the rain is a roll you will curse.

And it is not waterproof on its own, so put the tools in a bag inside it if that matters where you ride.

What owners say: “I've had the Odinsberg tool roll on my bike for 2 riding seasons now. It has held up well and I've had the unfortunate need to use it on at least 2-3 occasions. - Mr. D”

Generic. 1/4 in drive 6pt SAE 5/32 to 9/16 and metric 4-14 mm; 3/8 in drive SAE 1/4 to 7/8 and metric 10-21 mm; 1/2 in drive; deep sockets throughout; extensions in 3, 6 and 10 in for every drive.

The single best foundation for servicing a Harley yourself, and the reason is in the specification rather than the brand: every socket is 6-point, and the range covers SAE and metric across all three drive sizes with no gaps.

DEWALT's DirectTorque profile grips the flats rather than the corners, and the listing says it "helps prevent rounding of fasteners" - which, as covered earlier in this guide, is the actual mechanism behind rounded bolts rather than cheap steel.

It also includes Torx bit sockets T10, T15, T20, T25, T27, T30, T40 and T45 as standard, which covers the whole Harley Torx range in socket form so you can put a torque wrench on them. Plus hex bit sockets in SAE and metric, and three spark plug sockets including the 5/8 in a Harley uses.

A forty-year Craftsman owner who switched: "This is the best set of sockets you're going to find that covers all the sizes you will need in 1/4, 3/8, 1/2 drives." Another on the coverage: "5/32 to 1 inch and 4 mm to 24 mm you are covered. No skips."

The recurring complaint is the ratchets, and it is worth quoting because it is the pattern in this whole category: "These ratchets are really bad. I don't mean cheap or badly made, just badly designed. First off, they're HEAVY. It feels chunky and gritty on the pull back."

The other real problem is the case. Socket retention degrades with use, and owners report sockets falling out in shipping and when closing the lid.

Note also this is sockets only. No combination wrenches, no screwdrivers. And at nearly 40 pounds in a case about three feet across, it is a garage purchase, not something you take anywhere.

What owners say: “This is the best set of sockets you're going to find that covers all the sizes you will need in 1/4, 3/8, 1/2 drives. This is coming from a Craftsman guy for the last 40 years. - Linda”

Generic. SAE and metric across 1/4, 3/8 and 1/2 in drives. Individual socket sizes are NOT itemised on the Amazon listing.

The alternative to the DEWALT set, and the trade is straightforward: you get 21 combination wrenches and 44 hex keys that the DEWALT set does not include, in exchange for a listing that will not tell you what sizes the sockets actually are.

The hex keys are the underrated part for a Harley. Forty-four of them in both short and long arm patterns, which matters because the recurring complaint about every roadside kit in this guide is that the hex keys are too short to reach recessed cover bolts. Here you get the long ones.

The ratchets are 72-tooth with a 5-degree arc swing and a head up to 25 percent thinner, which is a genuine advantage working around a primary cover or between exhaust pipes. An owner: "The 72-tooth ratchets are actually surprisingly crisp. I was working in a tight spot and having that smaller arc really helped."

Another on the overall value: "The range of SAE and metric sockets across 1/4, 3/8 and 1/2 drives is impressive, and the ratchets feel solid with smooth engagement."

The reservations are real and they come from Amazon's own review summary rather than a single unhappy buyer: "some report tools breaking on first use, and the drawers don't slide in and out smoothly." The case is divisive, with the summary noting "some finding it great while others describe it as cheaply made."

And there is a one-star report about condition on arrival: "I thought I was ordering new and never been opened tools. What came says otherwise."

The practical objection for this article: because individual socket sizes are not listed, you cannot confirm before buying that the SAE range reaches the larger Harley sizes. If that matters to you, the DEWALT listing itemises everything.

What owners say: “The 72-tooth ratchets are actually surprisingly crisp. I was working in a tight spot near the firewall, and having that smaller arc really helped. - Brian”

Generic. SAE: 1/4, 9/32, 5/16, 11/32, 3/8, 7/16, 1/2, 9/16, 5/8, 11/16, 3/4, 13/16, 7/8, 15/16, 1 in. Metric: 8 through 22 mm.

The one purchase that closes the SAE-and-metric problem completely. Fifteen SAE sizes and fifteen metric, no skips in either, so you never stop a job because the bike turned out to be metric where you assumed SAE.

For a Harley owner that is worth more than it sounds. As covered earlier, the chassis is largely SAE, there is at least one 10 mm, and newer bikes are trending metric. Owning both full sets removes the question.

The box ends are offset 15 degrees for finger clearance, and the listing claims off-corner loading "reduces fastener rounding, and delivers up to 25 percent more torque."

A daily professional user: "I work on heavy duty trucks, I use wrenches daily most of the time all day and they hold up great." Another: "Good quality wrenches with all the needed sizes. Comes with good secure storage racks."

Two things to weigh. The box ends are 12-point, not 6-point, which contradicts the buying rule this guide gives for sockets. On a wrench the argument is different - 12 points give you twice the access angles in a tight space, which is often the whole reason you reached for a wrench instead of a socket - but on a worn or soft fastener a 12-point end is more likely to round it. Know which you are dealing with.

And there is a specific, avoidable annoyance in the storage: "The holders for metric are different size than SAE, but no mention is made of that. I stretched some of the metrics trying to seat SAE and now a couple wrenches fall out." Label your racks.

Amazon's summary also flags that the size stampings are "so small and shallow that they're hard to read".

What owners say: “This wrench set is great. I work on heavy duty trucks, I use wrenches daily most of the time all day and they hold up great. - Jandell Mendez”

Generic 1/2 in drive. Covers the larger fasteners a general set stops short of, including Harley rear axle nut sizes. Adapters step down to 3/8 in and up to 3/4 in drive.

The set that covers what the others do not reach. Most general mechanics sets stop around 7/8 or 1 inch, and Harley driveline and axle hardware goes well past that. This one runs to 1-1/4 inch.

It is also impact rated, which matters because the mainshaft and compensator nuts covered earlier in this guide are the kind of fastener people describe as needing "several 100lbft of breaking force". Chrome sockets on an impact gun shatter. These do not.

Sixty-three sockets in deep and shallow, SAE and metric, all 6-point with laser-etched sizes, plus 3, 5 and 10 inch extensions and a 72-tooth 1/2 inch ratchet.

A sceptical buyer converted: "I looked at many sets, I needed one for work with this amount of sockets and sizes and I got to tell you I was very very skeptical! And I got to say what can you possibly get for that amount of money?" Another: "I have a ton of sockets but not impact rated, so I saw this kit and decided to give it a shot. Seems well made."

Two limits worth stating. It is 1/2 inch drive only, so this is a supplement to a general set rather than a replacement for one. And impact sockets in black phosphate are physically bulkier than chrome, which restricts access in the tight spaces around a primary or transmission - use your chrome 3/8 sockets in there and save these for the big stuff.

The one recurring complaint is the case: "If the case latches stayed closed I'd give this 5 stars."

What owners say: “I was very very skeptical! And I got to say, what can you possibly get for that amount of money? - Brian”

For all Big Twin and XL. Listed fitment includes FLHR Road King 1994-1998, FLHT Electra Glide 1986-1998, FLSTC Heritage 1988-1999, FLSTF Fat Boy 1990-1999 and FXD Dyna. Needed for compensator, clutch, primary chain, inner primary seal and starter shaft seal work.

Nine dollars and fifty cents, and without it several jobs on a Harley simply stop. This is the first thing to buy in this section.

To break the compensator, clutch hub or sprocket nuts you have to stop the primary drive from turning, and there is nothing to hold onto. This wedge drops between the chain and the motor sprocket and jams it. The factory equivalent costs roughly $74.

The clearest statement of why you need it, from an owner: "If you own a Harley Davidson motorcycle and work on it yourself you are probably going to need one of these or something else to lock up the primary drive at some point in time. Essential if you are replacing the primary chain."

Another found a second use: "Used to lock the primary chain, but I also used it to lock my drive shaft sprocket which requires several 100lbft of breaking force."

Now the honest part, and it matters. This is a consumable. Amazon's own review summary records that "several customers reporting that it breaks easily and violently shatters during use", which given where your hands and face are during a compensator job is worth taking seriously. Another owner: "It works, not the greatest. Will work a few times, but not durable."

And even a happy owner notes the wear: "Used two on three disassemblies. The sprocket left small teeth marks in the delrin but that is expected."

Buy two. At $9.50 each that is still a fraction of the factory part, and running out of locking tool halfway through a primary strip is a bad afternoon.

What owners say: “If you own a Harley Davidson motorcycle and work on it yourself you are probably going to need one of these or something else to lock up the primary drive at some point in time. - Ed T.”

Fits 1936-2006 Big Twins and 1999-2006 Twin Cam. Does NOT fit 2006 Dyna. Owners also report it works for Sportster transmission bearing removal. Note the nut is reverse threaded on some models.

The transmission mainshaft pulley locknut is 1-7/8 inches across and sits down a shaft, so it needs a socket 5.5 inches deep. Nothing in a normal socket set is both. That is the entire reason this tool exists.

An owner, in five words: "Don't try the job without it."

At $19 it is a fraction of the major-brand equivalent, and an owner working on an 83 FLHS makes the comparison: "This item was a fraction of the cost of the major brand which I was really trying to avoid paying almost 10 times more for."

It comes with a threaded bushing that centres the tool on the shaft and protects the mainshaft threads, which is not a detail to skip - this is a job where damaging the threads turns an afternoon into a gearbox rebuild.

Two warnings that come straight from the reviews. The nut is reverse threaded on some models and it is savagely tight: "my nut was reverse thread. And it might have broke my impact getting the sucker off." Remember from the torque section that a click torque wrench does not click counter-clockwise, so do not rely on one here.

And there is a workaround worth knowing about, from an owner who did not buy a second locking tool: "You can lock the sprocket by turning the mount for the shift linkage upside down and locking it against a tooth." That is exactly the kind of thing no catalogue tells you.

Check the fitment carefully. Coverage stops at 2006 Big Twins, it explicitly excludes the 2006 Dyna, and Twin Cam 96 and Milwaukee-Eight owners need a different size.

What owners say: “Don't try the job without it. Also my nut was reverse thread. And it might have broke my impact getting the sucker off. This socket is solid. - Steve”

For 1984-2021 Harley spin-on oil filters, EXCEPT 2015-and-later XG (Street) models. Fits filters with 14 flutes. Sized so it clears the crank position sensor without crushing it.

Nine dollars, and it is the tool that turns a Harley oil change from a wrestling match into a two-minute job. The specification is the important part: 76 mm, 14 flutes, 3/8 inch drive.

It has to be a cap wrench rather than a strap or three-jaw type because on many Harleys the filter sits right behind the crank position sensor with no room to swing anything. The listing addresses that directly: it will "fit oil filters found behind crank sensor without crushing it."

An owner in exactly that situation: "I had an oil filter that was over tightened when installed and damaged when attempting to remove. Using this tool, I got it off."

Now the honest warning, because this listing has a 4.3 rating for a reason and the reason is instructive.

The steel is thin. An owner: "Thin material. If over tightened filter, it's not as effective." Another, at three stars: "Not great but does fit and work. Better to spend a little more money to get a higher quality tool." Amazon's review summary names it as the main complaint: "multiple customers reporting that it slips off the filter during use."

The mechanism is simple. Thin stamped steel flexes under load, climbs off the flutes, and rounds them. So if a shop fitted your last filter with an impact gun, buy a thicker or forged cap instead of this one. If you fit your own filters hand-tight, this is all you need.

The second issue is fitment inside the stated range. A one-star review reads: "Totally wrong for my 2013 street glide despite that it says it will work." Flute count and diameter vary by filter brand as well as by bike. Count the flutes on the filter currently fitted before you order.

What owners say: “I had an oil filter that was over tightened when installed and damaged when attempting to remove. Using this tool, I got it off. - Tonya”

Generic. Covers T20, T25, T27, T30, T40 and T45, the sizes a Harley actually uses, plus the tamper-proof centre-pin versions. Does NOT include external (E-Torx) sockets.

If your roadside kit came without Torx, or with only three sizes, this is the set that closes the gap permanently.

Full T6 to T70 range, which covers every size a Harley uses on derby and inspection covers, rotor bolts, controls and fairing hardware, plus the tamper-proof versions of the same sizes for the fasteners with a centre pin.

The critical difference from a set of Torx keys is that these are bit sockets. That means you can put a torque wrench on them, which matters because Harley cover screws have inch-pound specs and stripping an aluminium cover is the everyday consequence of guessing.

An owner describes the coverage: "Well made. Durable. Full set, metric and standard, in security type and hard use type in all sizes each. 1/4, 3/8 and 1/2 drives as appropriate to sizes of bits."

Two cautions. Bit sockets are two-piece by design, so the bit can pull out of the socket and stay in the fastener. Annoying rather than dangerous, but it happens. And one owner notes they are "just not as strong as I'm used to" against premium solid keys.

The other warning is one of the more useful things in the reviews and applies to any Torx purchase: "Be aware there is a difference between spline drive and Torx bits even though one appears to fit the other. Get a set of each." A spline bit in a Torx head, or the reverse, will round both.

Note also what this set does not include: external Torx. E4 to E24 is a separate purchase, covered below.

What owners say: “Well made. Durable. Full set, in security type and hard use type in all sizes each. 1/4, 3/8, and 1/2 drives as appropriate to sizes of bits. - Joshua B. Johnson, Jr.”

Generic. 1/4 in drive: E4, E5, E6, E7, E8. 3/8 in drive: E10, E11, E12, E14, E16. 1/2 in drive: E18, E20, E22, E24. These are the OPPOSITE of Torx bits - for star-headed bolts.

Fifteen dollars to close the gap that a Torx bit set leaves open, and most people do not know the gap exists until a bolt head defeats them.

External Torx, also called inverted Torx or E-Torx, is a star-shaped bolt head rather than a star-shaped socket in the bolt. A Torx bit will not touch it. What it needs is a socket with a star-shaped hole, and that is a separate product from every Torx set on the market.

The danger of not owning them is specific: an E-Torx head is close enough to a metric hex that a socket will half-fit, and half-fitting is how you round a bolt head off.

Fourteen sizes from E4 to E24, split sensibly across three drive sizes so the little ones are on 1/4 inch and the big ones on 1/2 inch. Chrome vanadium, each socket etched with its size, in a case that fits a toolbox drawer or a tool pouch.

The honest caveats are about evidence rather than the product. Only 102 ratings, with no visible one to three star reviews, so long-term durability is unproven. And the reviews are dominated by car owners - a Lexus, a Mercedes - rather than Harley owners, so there is no Harley-specific fitment confirmation on the page.

Note also a piece count discrepancy: the title says 14 sockets and the product details table says 15. And these are chrome vanadium, not impact rated, so keep them off the gun.

Buy them anyway. Fifteen dollars against a rounded bolt head is not a close call.

What owners say: “Good set of star sockets. I needed these to remove the lower studs on an engine block. They fit perfectly and work as expected. - Douglas / Ken Koebel”

Universal motorcycle and bicycle spoke nipples. For laced wheels only - irrelevant if you have cast wheels. Measure your own nipples before ordering, because no Harley-specific size is confirmed on the listing.

Only relevant if you have laced wheels, and essential if you do.

Spoke nipples are soft and the flats are small. A crescent wrench or a pair of pliers will chew them, and a chewed nipple is a wheel-building job rather than a tensioning job. Eleven dollars stops that happening.

Six sizes in one body - 6.5, 6, 5.7, 5.5, 5 and 4.4 mm - so it covers most of what you will find without a separate wrench per wheel. And at 3.5 inches and 3.5 ounces it lives in a tool roll without being noticed.

An owner who was not expecting much: "It seemed small and insignificant. This little tool really works very well. Was easy to go around with the prescribed method to tighten." Another on why it works: "tough little tool with extra width to easily grab the spoke."

Two honest caveats, both from the listing rather than the reviews.

First, check your nipple size before ordering. There is no Harley-specific size confirmation anywhere on the page, and there is a documented fitment failure on another bike: "Didn't fit my 2020 ktm 450 xcf spokes." As one owner puts it: "Ensure it covers your spoke nipple size before ordering. That should be common sense."

Second, the listing contradicts itself on material - aluminium in the specifications table, heavy duty steel in the bullets. Amazon's review summary also notes several customers finding it oversized, and records that "customers disagree on the value for money."

For eleven dollars before a long trip on laced wheels, it is still the right buy.

What owners say: “It seemed small and insignificant. This little tool really works very well. Was easy to go around with the prescribed method to tighten. - Joseph Clore”

The band Harley cover screws live in: derby and inspection covers, timer cover, primary cover bolts, sensor and bracket hardware. 20 in-lb is about 1.7 ft-lb, so this reads what a ft-lb wrench cannot.

This is the torque wrench most people do not own and most people need. Put it above the ft-lb wrench in your buying order.

The reason is arithmetic. A 10 to 80 ft-lb wrench cannot read below 10 ft-lb, and almost every cover screw, bracket bolt and sensor fastener on a Harley sits below that. This one covers 20 to 200 in-lb, which is roughly 1.7 to 16.7 ft-lb.

An owner says exactly what this article is saying: "I had a ft/lbs torque wrench but not an in/lbs one, so this was a welcome addition to my tool hoard." That is the pattern.

At 10.88 inches long it fits between a derby cover and a floorboard, which a longer wrench does not. It comes with a 6 inch extension and a 1/4 to 3/8 adapter in the box, and it is pre-calibrated to plus or minus 4 percent.

A detailed owner assessment: "The build quality is excellent, the calibration feels spot-on, and the click is clear without being overly loud."

The failure mode to know about is the adjustment mechanism, and Amazon's summary names it: "durability is a concern as multiple customers report the ratchet mechanism coming apart." One owner is specific: "the locking/unlocking mechanism is rough to use which I believe makes the internal thread strip easily. This is my 2nd day with this tool and now it is technically broken."

Wind it back to zero after every use. A wrench stored under spring tension both drifts out of calibration and stresses exactly the threads that are failing here.

And remember the rule from the torque section: it does not click counter-clockwise, so it is no help on a reverse-threaded nut.

Drain plugs, oil filter, calipers, rotors, exhaust and most chassis fasteners. Note the 10 ft-lb floor: everything below that needs the in-lb wrench above.

The second of the two wrenches, and the one most people buy first. It covers drain plugs, the oil filter, calipers, rotors, exhaust and most chassis hardware.

An owner on the jobs it is for: "I mainly bought it for tightening the oil filter housing and engine oil drain plug, and it's been spot on. The click is clear and easy to feel, giving confidence that everything is torqued correctly without over-tightening."

That last phrase is the point. As the torque section covered, the documented damage on a Harley is over-tightening, not under-tightening. A crushed oil filter and stripped cover threads are what this wrench prevents.

Another owner checked it against a known-good wrench: "I tested first on a lug nut at a lower setting (30 lbs) and it worked. I used my other 1/2 inch torque wrench at same setting and they appear to be very close."

At 14.5 inches it is short enough to swing in a primary or around exhaust pipes, which longer 1/2 inch wrenches are not.

Three warnings.

The 10 ft-lb floor. An owner states it plainly: "On the foot pound side of the torque wrench, the lowest setting is 10 foot pounds." Everything smaller needs the in-lb wrench.

It only works clockwise. Another owner: "In the documentation, it clearly states that the torque wrench function only works in the clockwise direction. This is where it can catch you out." Harley uses reverse-threaded nuts in the driveline on some models.

It is not a breaker bar. The most detailed failure report is from someone who used it as one: "I used this torque wrench twice and it broke on me while I was trying to remove a bottom bracket. One of the ratchet mechanisms has cracked." Amazon's summary confirms breakages are a theme.

Standard Schrader valves. The angled head helps on the 90-degree valve stems common on cast motorcycle wheels.

Seven dollars fifty, and it matters more on a Harley than on a car. A bagger running a few psi low on a rear tyre handles badly, wears the centre out and gets hot. The gauge in your kit is probably a $3 pencil type that is out by three or four psi.

Plus or minus 1 psi, calibrated to ANSI B40.7, reading in 0.1 psi steps. A mechanic's wife reports the sanity check: "My husband is a mechanic, and he did test the accuracy of this gauge with many of his other ones, and he determined it is accurate."

The two features that matter for a motorcycle are the angled head and the lit nozzle. An Italian owner explains the first: it works both on car valves that are perpendicular to the rim and on motorcycle valves that sit at 90 degrees. Another: "Nice angle to help with the reading of the air in the tires."

The lit nozzle is for finding a valve stem behind a spinning rotor in a dark garage, and it is more useful than it sounds.

The reservations are all about longevity. Amazon's summary is direct: "the gauge stopping working after minimal use and breaking within a year", plus "the battery life is problematic, with customers noting it eats through batteries quickly." One owner reports a persistent seal problem: "It has always been difficult to maintain a good seal to get an air pressure reading."

Battery access varies by production run, and some units need two screws removed to change them.

At $7.50 it is a consumable. Buy it, use it, replace it when it dies, and do not build a routine around it lasting a decade.

Generic. For charging voltage, stator output, parasitic draw, switch continuity and broken grounds - which between them account for most Harley no-start complaints.

Most Harley no-start and dead-battery complaints are electrical, and most electrical faults are found with a $35 meter rather than a $500 scanner. This is the tool that tells you whether the charging system is actually charging.

True RMS and auto-ranging matter here for a specific reason: checking stator output means measuring AC, and a cheap averaging meter reads AC inaccurately. This one does not.

What you will actually use it for: charging voltage at the battery with the engine running, stator output AC volts, parasitic draw with the bike asleep, continuity through switches and handlebar controls, and tracing the broken ground that is causing three unrelated symptoms at once.

An owner comparing it against professional gear: "I've had mine for about 11 months now and I'm very happy with it. It seems to be accurate for measuring voltage on a 12 volt automotive battery when compared to SnapOn and Fluke multimeters." Another: "This meter replaced my trusty 80's era Fluke, and I regret not doing it earlier."

Practical details that matter on a bike: a magnetic hanging loop and a kickstand, so it can sit on the frame while you probe with both hands.

Two things to plan for. The supplied test leads are the weak point - "Great multimeter. Test leads are worthless for my applications though" - and Amazon's summary records "wires breaking after less than six months of use." A separate set of leads with alligator clips and piercing probes is a worthwhile $15.

And there is no carry case, and no clamp for measuring current without breaking the circuit.

4-pin: 2001-2010 Softail, 2001-2011 Dyna, 2001-2013 Touring, 2006-2013 Sportster. NOT 2001-2003 carburetted. 6-pin: 2011-present Softail, 2012-present Dyna, 2014-present Touring, 2014-present Sportster, 2014-present Street, all current Trike.

The cheapest possible entry to Harley diagnostics, and the listing that spells out the connector reality more clearly than anything else on Amazon.

A Harley does not use the 16-pin OBD2 socket. It uses a round 4-pin or a round 6-pin depending on year and family, and the fitment list above is quoted from this listing. Note the exclusion: 2001-2003 carburetted models have nothing compatible at all.

This cable converts the round connector to a 16-pin socket so a car code reader or a Bluetooth OBD2 dongle can plug in. An owner: "This diagnostic cable worked perfectly with my scan tool reader, was able to track down the problem with my bike."

Now read the two sentences the seller puts on their own listing, because they are the honest limits of the whole approach.

"The diagnostic cable only acts as a link." It is a physical adapter. It adds no protocol support. Your reader still has to speak the language your bike speaks or nothing comes back.

"This is the Can-bus version, not K-line, please note!" Those are different protocols and the cables are not interchangeable. Buy the wrong one and nothing happens.

The reviews split accordingly. Amazon's summary: "some saying it works like it should while others report it doesn't work at all." One owner found his miswired: "I checked against diagram of wires supplied in pics and #3 and 4 on the 4 pin were reversed, so I repaired it but still wouldn't get info from Harleys."

Another bought two and neither worked. If yours does not work, that is almost certainly the wrong protocol rather than a bad unit, and buying a second identical cable will not fix it.

Fifteen dollars is a reasonable gamble if you already own a reader. It is not a reasonable expectation of full diagnostics.

Designed ONLY for Harley-Davidson with a round 4-pin or 6-pin diagnostic port. ABS bleeding available on compatible models THROUGH 2023 ONLY, not 2024 or newer. Fuel injected bikes only, not carburetted. Second cable gives basic 16-pin OBD2 car reading.

The tier where real capability starts, and also the tier where you have to check your specific model year before buying rather than after.

When it works, it does what people actually want from a Harley scanner. A 2009 Dyna owner: "Works perfectly on my 2009 Dyna and read the modules etc. Highly recommend! It can activate your spark plug coils, activate your turn signals, activate your ABS module, view live data." Another with three bikes: "Works with the 3 Harleys I have. Can flush ABS brakes, read and erase codes, lots of information."

Being able to bleed ABS at home is the single biggest argument for this tier, because it is a job most owners otherwise pay a dealer for.

But this listing has a 3.6 rating from 23 ratings, and the negative reviews are not about build quality. They are about coverage.

A one-star from an owner with two bikes at opposite ends of the range: "Does not work for either of my Harley's 2024 RG or 2009 ultra. It reads the VIN but does nothing else. Put the latest software on and it's still trash." Another on an early fuel-injected touring bike: "I was unable to pull any codes or diagnostics on my 2003 Ultra Classic Electraglide" - and he then paid over $20 to return an item listed with free returns.

Note also the listing's own limit: ABS bleeding works through 2023 and is unavailable on 2024 and newer bikes. And it is useless on carburetted machines, as a Spanish-speaking owner found: "Solo para motocicleta con sistema fuel injected."

One ergonomic complaint worth knowing: no internal battery, so it only powers up plugged into a live bike. "I don't like the fact it doesn't have its own battery, cables going everywhere."

Check your year and model against the seller before you buy. The results here are genuinely model-year dependent.

Harley plus BMW, Ducati, Kawasaki, Suzuki, Yamaha, Honda. For Harley you need the separately sold M013 adapter for the 4-pin/6-pin port. Coverage varies by model.

The dongle approach rather than a handheld: a pocket Bluetooth unit and an app on your phone. The genuine advantage is size, and one owner explains it well: "I like that it is small enough to connect and put covers back on bike so I can test ride" while watching live data.

That is a real capability. Diagnosing an intermittent fault while actually riding is something no handheld with a cable does.

It scans engine, ABS, BCM, instrument, TPMS, suspension and speedo depending on model, and it is bi-directional, so it can command lamps, relays, fans, brake lights, the tachometer and the fuel pump. Owners report it paying for itself: "This TopScan Moto scanner saved me time and money 2 times already. First on my 2015 Harley Davidson Tri Glide and again on my wife's."

Now the three things that pull the rating down to 3.7, and you should weigh all of them.

The Harley adapter is not in the box. The listing says the M013 4-pin/6-pin adapter is sold separately. One buyer could not test his Harley at all: "Should work on my Harley too but might be the same deal. I can't confirm since I didn't buy the patch cable for it yet."

The subscription gate. An owner does the maths: "you can not clear the annual service due light without a ONE YEAR subscription for $99.00 more. So if all you really need to do is clear that, it will cost you well over $250." The software is free for the first year and cannot be used at all after the licence expires.

Hardware failure rate. "2 of 2 failed to turn on Bluetooth, but the 3rd functioned as advertised."

Buy it if you want live data on a test ride and you have priced in the adapter. Do not buy it purely to reset a service light.

Supports selected Harley-Davidson, Honda, Yamaha, Kawasaki, Suzuki, Indian, Polaris, BRP and Victory models. The listing states that compatibility varies by make, model, year and ECU. Verify your bike before buying.

The workshop tier, and it is included here with a warning rather than a recommendation.

What it does that nothing cheaper does: ECU coding, module initialisation, VIN writing and immobiliser setup on supported models, plus thirty-plus service functions including ABS bleeding, throttle calibration, TPMS relearn, oil reset and drive belt reset. It is a standalone Android tablet with its own screen and battery and nine brand adapters, so it is not tied to a phone or a laptop.

Owners who got it working are enthusiastic: "A must have tool to save money and diagnose issues. And customer service and support from ANCEL - I've never had so much support for updating my tool with success." Another: "Plug in and it tells all. Great tool and saved big bucks doing self diag."

Now the reason this is at the bottom of the section rather than the top.

At $540, a one-star review reads: "Did nothing more than the 39 dollar one I had." Another: "this scanner did not identify 4 out of 4 motorcycle / quads. Which means it did not do anything that it stated in their videos to promote this scanner."

That is the finding that should shape how you read this whole category: price does not reliably buy compatibility. Coverage is decided by whether the manufacturer has written support for your specific model and ECU, and no amount of money forces that.

Two more practical issues. Updates are Windows only - "If you only own a Mac you can forget about updates" - and the update process itself has failed for owners, with support replies taking over a day.

136 ratings at 4.2 is thin evidence for a $540 purchase. Email the seller with your exact year and model and get a written answer before you buy. That advice applies to everything in this section, and most of all to this.
