Motion Pro SlackSetter Chain Tool - Compact Nylon Gauge, Anodized Aluminium Scale, Measures Up to 75mm

The Motion Pro SlackSetter Chain Tool is a purpose-built gauge for checking and adjusting drive chain play on most street and off-road motorcycles. Its lightweight engineered-nylon body plus an anodized aluminum, laser-etched scale give a durable, travel-friendly device that replaces guesswork with repeatable measurements. Designed by Motion Pro engineers and race-tested for daily use, this tool streamlines routine chain maintenance so you can protect sprockets and extend chain life when set to your manufacturer's specifications.

How does the SlackSetter make chain adjustment faster?

The tool gives a simple, repeatable reference point so you measure slack the same way every time, reducing fiddling and second-guessing at the rear axle. Instead of eyeballing sag, the SlackSetter provides a clear numerical scale you can use during adjustment checks or when setting the bike on its stand.

• Two scales: chain slack and chain-to-swingarm clearance for dual checks
• Quick placement over the chain for immediate reading
• Compact size fits in a toolbox or roadside kit for fast field use

What motorcycles and slack ranges is it compatible with?

Built to serve a wide range of street and dirt bikes, the SlackSetter covers common chain play requirements used by most manufacturers. It accommodates generous movement ranges so you can measure bikes with different swingarm and chain designs.

• Works on most street and off-road motorcycles
• Measures chain slack up to 75 mm (about 3") for broad compatibility
• Useful for both light trail bikes and heavier road machines

What materials and features ensure accuracy and durability?

The gauge combines modern polymers with a precision metal scale to balance toughness and measurement fidelity. The anodized, laser-etched aluminum scale resists wear, while the engineered nylon frame keeps the tool lightweight and impact resistant for garage or travel use.

• Engineered-nylon body for strength and low weight (approx. 0.15 lb)
• Anodized aluminum measuring scale with laser-etched graduations for long-lasting clarity
• Patented design developed from Motion Pro’s racing and engineering experience

How should I use the SlackSetter to get reliable readings?

Follow your motorcycle owner’s manual for the specified slack range and measurement procedure, then use the SlackSetter as the physical reference for that measurement. Place the tool where the manual indicates chain slack is to be measured, read the scale, and adjust the rear axle until the correct value is achieved.

• Refer to your owner’s manual for the correct slack value and measurement location
• Use the SlackSetter on a cold chain or as the manual recommends for consistency
• Keep the gauge in your tool kit for quick roadside checks after long rides

Who is this for: Riders and mechanics who want a dependable, repeatable method for measuring chain slack—especially those who perform regular maintenance, prepare bikes for long trips, or work on multiple machines. The Motion Pro SlackSetter is suited for enthusiasts, track-day mechanics, and professional shops that value speed, accuracy, and a tool that travels well.
