Starter bendix 101 OCTANE 14/63 Aprilia Derbi Gilera Piaggio Vespa 50cc 2-stroke

Starter clutch for Aprilia, Derbi, Gilera, Piaggio and Vespa 50cc 2-stroke scooters.

The starter clutch creates the link between the starter and the crankshaft. The clutch secures the components if the motor is turned on and the engine revs are more than the starter motor revs. Crunching and knocking when starting often point towards a problem with the starter clutch. Leaving it could cause major damage to the engine cases.
