# Centrifugal clutch

> A centrifugal clutch is the automatic clutch in scooters whose shoes swing out under centrifugal force as revs rise and grip the clutch bell to drive the wheel.

- **Also known as:** Otomatik debriyaj, Debriyaj pabucu, Kampana, Clutch shoes

At idle, springs hold the shoes in and the scooter does not move. Opening the throttle swings the shoes out against the clutch bell and the rear wheel starts to turn. The engagement speed is set by the stiffness of the shoe springs.

## Symptoms of a problem

- Judder when pulling away – the shoe or bell surface may be glazed or uneven
- Revs rise but the scooter accelerates slowly – worn shoes are slipping
- The scooter creeps forward at idle – weak springs

Inspect the shoes and bell together; replace the bell if its inner surface is beyond the wear limit.
