Fitment and maintenance

Match the sprocket family and mounting pattern to the motorcycle model and year. Confirm chain size, tooth count and clearance before ordering. A change in tooth count changes final-drive gearing and can affect the chain length and adjustment required.

Inspect the chain and both sprockets together. Install to the motorcycle manufacturer’s assembly and torque specifications, then check chain adjustment and lubrication.
