Moturo Racing clutch bell for 47-49cc pocket bike

Moturo Racing clutch bell with 6-tooth pinion for 47-49cc pocket bikes

The Moturo Racing clutch bell for pocket bikes and dirt bikes with 47-49cc two-stroke engines — a drive component that transfers torque from the clutch to the drive chain. 6-tooth pinion for better acceleration, support bearing, ready to install.

The clutch bell sits between the centrifugal clutch and the drive chain of your pocket bike. It receives torque from the clutch shoes and transfers it to the drive chain via the integrated 6-tooth pinion. The version with a 6-tooth pinion provides noticeably better acceleration than a 7-tooth pinion — shorter gear ratio, more pull from a standing start. Suitable for air-cooled two -stroke pocket bike and dirt bike engines with 47cc and 49cc. The included support bearing holds the bell in axial position.

Can be replaced in about half an hour with a hex key set, socket wrench, and torque wrench.

Frequently asked questions

Does this set also fit 50cc four-stroke pocket bikes?
No. Designed for air-cooled two-stroke engines with 47cc and 49cc.

What is the advantage of the 6-tooth pinion over the 7-tooth pinion?
Shorter gear ratio and stronger acceleration from a standing start. The top speed is consequently slightly lower.

Does this drive part need to be registered?
No. Chain and drive components are standard wear parts; what matters is the correct pitch, dimensions, and proper installation.
