Best Torque Wrenches
The most important specialty tool you can buy for your motorcycle
As motorcycle technology has advanced, the tolerances to which they are manufactured have gotten ever tighter. While torque wrenches have always been important, modern motorcycles, and particularly their engines, depend on the exacting tightening specifications allowed by a torque wrench. Every motorcyclist should have one to assist them in their home-mechanic efforts.
When looking for a torque wrench, it’s easy to get lost in the woods of specifications and prices. To ease your buying decision, look for these attributes: brand, size of ratchet drive, type of wrench, quality, and price. When choosing a brand, go with one that has a good reputation. You may save some money with a no-name brand, but the quality and durability may be suspect. The size of the square drive on the ratchet will determine what sockets can be mounted to it. Larger, higher-torque fasteners will usually require a 1/2-inch drive, and smaller, a 3/8-inch drive. (In my toolbox, I have both a 1/2-inch and 3/8-inch drive for foot-pounds and inch-pounds, respectively.)
As you choose the type of torque wrench you buy, stay away from the cheap bar-type, which is hard to use and easy to misread. While I have always used click-type torque wrenches, which briefly release with a click when the specified torque is reached, digital torque wrenches, which use a beep and/or vibration to let you know when proper torque is reached are increasingly popular. Since quality and price often go hand-in-hand, you should avoid the cheapest ones but the average user doesn’t need to go out and buy the most expensive one, either. Look for calibration accuracy of around 4%-5%.
Below, you will find a listing of some of the best torque wrenches we can find, based on the manufacturer’s reputation, specifications, and reviews.

1. CDI (Snap-On) 1503MFRPH 1/2-Inch Drive Adjustable Micrometer Torque Wrench
While you may not have heard of CDI tools, if you know anything about mechanics’ tools, you’ve heard of Snap-On, and CDI is a subsidiary owned by Snap-On. Consider this click torque wrench for those who want quality tools but don’t want to sell their first-born child to get them. Depending on the motorcycle you own, you can buy a 20-150 lb-ft or 30-250 lb-ft model. You’ll get a 25-inch long wrench to assist with higher values, while the ratchet itself allows for use in either direction. The laser-etched scale is easy to read, and the setting has a positive lock with spring-loaded pulldown lock ring. A calibration certificate is included with the wrench. CDI also makes torque wrenches with 1/4- and 3/8-inch drives.

2. GearWrench 85077 1/2-Inch Digital Torque Wrench
This digital torque wrench offers five different torque unit measurements: Nm, ft lb, In lb., kgf m, and kg cm. Once set to a value, the “Target torque alert” warns as you approach the target torque, and tells the user when the value is reached with a vibrating handle, buzzer, and solid LED light. The 72 tooth ratchet allows for ratcheting increments as small as 5°. The certified accuracy is an astounding +/- 2% between 20% and 100% of the wrench’s minimum and maximum torque values.
- 2% accuracy!
3. TEKTON 1/2 Inch Drive Click Torque Wrench
As the name implies, this 26-inch torque wrench uses a click to tell you when the desired setting is reached. The 1/2-inch drive wrench includes its own storage case. The desired value is set via a high-contrast dual-range scale. Although the ratchet rotates in both directions, torque is only measured for clockwise rotation. The all-steel wrench is calibrated to +/- 4% accuracy.

4. ACDelco Tools ARM601-3 3/8” Digital Torque Wrench
Torque wrenches with a 3/8-inch drive are ideal for smaller bolts with lower torque requirements. This 12.25-inch torque wrench measures values between 2-37 lb-ft with an accuracy of +/- 2% clockwise +/- 3% counter clockwise of indicated value within a range of 20% to 100% of full scale. The LCD screen displays kg-cm, N-m, in-lb, and ft-lb. The built-in buzzer notifies the user when the desired value is reached. Meets or exceeds ASME B107.14-2004, ISO 6789 standards, individually serialized with matching certificate of calibration traceable to N.I.S.T.
- Ideal digital torque wrench for smaller fasteners
5. eTORK Click-Style Torque Wrench (3/8-Inch Drive)
This 3/8-inch drive torque wrench features a 45-tooth ratchet that allows for torque measurement in both clockwise and counterclockwise directions. The wrench is calibrated to +/- 3% accuracy in a clockwise direction. The hardened alloy steel housing features a soft-grip handle for comfortable use.

Torque Wrench FAQ
Do I really need a torque wrench?
In a word, yes. Over tightening or under tightening fasteners on your motorcycle can get very expensive very quickly – and that’s before we even consider the potential risk you would put yourself under with improperly-tightened bolts. Have you ever seen a bike with a missing rear axel nut? It’s not something you want to experience first hand. However, having a quality torque wrench is only half of the equation. You also need to know what values to set it to. So, you should also buy your motorcycle’s factory service manual.
Is it OK to loosen bolts with a torque wrench?
Again, in a word, no. A torque wrench is a precision measuring instrument, not a breaker bar. If you use a torque wrench to loosen fasteners, you run a very high chance of knocking it out of calibration and effectively rendering it useless. So, don’t throw away your money.
What happens if you don’t use a torque wrench?
Basically one of two undesirable possibilities await an improperly torqued fastener. First, if you over torque the fastener, you can feel the sudden looseness of stripped threads or a broken bolt – both of which set you up for potentially time-consuming repairs. Second, if the fastener is too loose, it could spin free, leading to potential component failure. Think for a moment about a cylinder head that is not torqued down. Do you really want to take your engine apart again because the head gasket is leaking. Now imagine the dire consequences of a loose nut on the bike’s suspension or wheels. These can easily become life-or-death hazards.
