Motion Pro SlackSetter chain slack tool — compact dual-scale gauge with anodized aluminum scale

The Motion Pro SlackSetter Chain Tool is a compact, patented gauge that measures and helps set motorcycle chain slack accurately for longer chain life and safer riding.

Keeping chain slack within the limits specified by your motorcycle manufacturer extends sprocket and chain life, improves driveline performance, and reduces the chance of premature wear. The Motion Pro SlackSetter is engineered to make that job fast and repeatable: a lightweight nylon body with an anodized, laser-etched aluminum scale provides dual measurements for both chain slack and chain-to-swingarm clearance on most street and dirt bikes.

How does the SlackSetter measure chain slack so quickly and reliably?

The device uses a precisely angled contact and an easy-to-read anodized aluminum scale to capture slack consistently. Its patented geometry indexes to the chain in the same spot each time so you can repeat measurements with minimal variance.

• Dual scales for chain slack and chain-to-swingarm clearance (millimeters)
• Laser-etched aluminum scale for clear, long-lasting markings
• Patented contact point and geometry to reduce user error
• Works across a wide range of chain amplitudes up to the listed maximum

Will this tool fit my bike and workshop routine?

The SlackSetter is compact and lightweight, designed to live in a toolbox or a roadside kit. It accommodates most street and off-road motorcycles and handles the typical range of slack specifications mechanics encounter.

• Compact footprint fits easily in tool kits and drawers
• Designed for most street and dirt bikes with typical chain ranges
• Durable engineered nylon body resists shop abuse
• Quick to use during routine maintenance or roadside checks

What accuracy and durability features does Motion Pro include?

Motion Pro built the SlackSetter with materials and finishes chosen for clarity and longevity. The anodized aluminum scale is laser-etched to prevent wear, while the engineered nylon body balances impact resistance with low weight.

• Anodized aluminum measuring scale resists corrosion and wear
• Laser etching keeps measurement marks readable over time
• Engineered nylon construction for toughness and light weight
• Patented design reflects Motion Pro’s professional-racing development input

How should I use this tool with my owner's manual recommendations?

The SlackSetter is a measuring aid — always follow your owner’s manual for the correct slack specification and adjustment procedure. Use the SlackSetter to confirm your adjustment results quickly, then recheck the recommended measurement points and method described by the manufacturer.

• Consult your owner's manual for the exact slack specification and procedure
• Use SlackSetter to measure and verify after adjustment
• Not intended as a replacement for official service instructions
• Best practice: measure at the same chain point and under the same conditions each time

Who is this for: The Motion Pro SlackSetter Chain Tool is aimed at motorcycle enthusiasts, home mechanics, and professional shop techs who want faster, repeatable chain slack checks without carrying bulky instruments. If you perform regular chain maintenance, enter races, ride off-road, or simply want to protect drivetrain components, this compact gauge makes a precise measuring step easy to add to your maintenance routine.
