This drive component sits directly on the output shaft and endures constant torque and abrasive grit. You should replace it when the teeth begin to hook or show visible thinning. Worn teeth accelerate chain wear and sap power from the rear tyre. This steel part is machined to match OEM spline tolerances for a precise fit. Always inspect the lock washer or circlip during your rebuild. If you are adjusting the tooth count for specific track conditions, verify your chain length and swingarm clearance. Changing the front size has a significant impact on your bike's final drive ratio.
