Motion Pro SlackSetter Pro chain tension gauge 52 mm (2") — compact, repeatable motorcycle chain slack tool

The Motion Pro SlackSetter Pro 08-0674 is a compact, easy-to-use chain tension gauge that lets you measure and set motorcycle chain slack quickly and accurately up to 52 mm (2").

Keeping proper chain slack extends chain life and improves drivetrain performance. The SlackSetter Pro from Motion Pro is a lightweight, pocketable tool designed for most street and off-road motorcycles. It provides a repeatable measurement so you can adjust tension with confidence, while purposely not serving as a swingarm-to-chain clearance gauge.

How does the SlackSetter Pro simplify setting chain slack?

The SlackSetter Pro gives a clear reference for the amount of free movement in the chain, removing guesswork from adjustments. Using it takes seconds — hook, pull to the specified amount, and read the fit — enabling consistent tension every time.

• Measures slack up to 52 mm (2") for common motorcycle chains
• One-handed operation speeds up roadside or shop adjustments
• Repeatable reference reduces over- or under-tightening

Will this tool work on my bike model and chain size?

The SlackSetter Pro is built for broad compatibility with most street and dirt bikes and works with typical motorcycle roller chain sizes. It’s not a model-specific tool, so check your motorcycle’s recommended slack range and confirm it falls within the tool’s 52 mm (2") limit.

• Suitable for many standard street and off-road chain applications
• Not intended for measuring chain-to-swingarm clearance specifications
• Compact size fits into tool roll or roadside kit

How durable and portable is the SlackSetter Pro for field use?

Designed to be lightweight yet robust, the SlackSetter Pro resists damage from routine workshop and trail use. Its compact footprint makes it a convenient addition to a toolbox or emergency road kit, so you can check and correct chain slack wherever you ride.

• Made for regular workshop and on-the-road use
• Small enough to store with other motorcycle tools and spares
• Simple construction minimizes breakage points

How precise is the measurement and how should I interpret it?

The tool supplies a direct physical reference for chain free play rather than a numerical digital readout, which keeps its operation straightforward and reliable. Match the tool’s setting to your motorcycle manufacturer’s specified slack range and adjust the axle accordingly until the tool indicates correct play.

• Provides a clear physical benchmark for free play, up to 52 mm (2")
• Use in conjunction with your bike’s service manual specifications
• Helps prevent premature chain wear from improper tension

Who is this for? The Motion Pro SlackSetter Pro 08-0674 is aimed at riders, mechanics, and hobbyists who want a quick, reliable method to set chain slack on a wide range of motorcycles. If you perform regular chain maintenance, travel with a compact tool kit, or tune multiple bikes, this simple gauge delivers consistent results without the complexity of larger measuring systems.
