The Clutch Bell R-Vent 125 mm is a ventilated aftermarket performance clutch bell designed for scooters equipped with GY6 125cc to 150cc engines, including models such as the Honda Ruckus GY6, Kymco, PGO, SYM, and other machines with GY6-type CVT transmissions.
In a CVT transmission, the clutch bell is the external surface against which the centrifugal weights (or discs) press under centrifugal force. It is this bell that then transmits torque to the CVT belt. A standard clutch bell can accumulate heat and lose efficiency under heavy use. The R-Vent version improves this performance thanks to a ventilated design, which promotes airflow around the friction surfaces and limits overheating.
Key technical features:
Controlled internal ventilation — machined openings/slots to facilitate airflow over the friction surface.
Precision machining of the friction surface ensures uniform contact with the clutch shoes/discs.
Enhanced thermal management results in faster heat dissipation during clutch cycles.
Compatibility with standard 125 mm size clutch bells and performance clutch kits for GY6 engines.
