Performance Benefits

The surface of this clutch bell is textured to grip the clutch better when you first pull away. Cross-drilling lets heat escape and helps clear out debris, which matters when you ride hard for long stretches. Fitting this bell can make your scooter feel more responsive and can help engine temperatures stay lower.

Installation and Compatibility

This clutch bell works with several 50cc and 80cc engines built on the 139QMB platform. It is shaped to slot straight into the existing setup on your scooter. When your engine code includes "QM" or "FM," this part will probably fit your vehicle. It's a strong choice for riders improving a stock scooter or building a high-performance drag machine.
