The Naraku R-Vent Clutch Bell is an aftermarket performance clutch bell specifically designed for scooters equipped with GY6 125cc to 150cc engines (e.g., Honda Ruckus GY6, Kymco, SYM, PGO, and other similar CVT platforms). It replaces the original clutch bell to provide improved heat dissipation, active cooling of internal components, and more consistent traction under load.
The clutch bell is the external contact surface for the centrifugal clutch weights or discs. As engine speed increases, these weights push against the bell to transmit torque to the CVT belt. A traditional smooth steel bell retains heat at the friction surfaces, which can lead to slippage, reduced efficiency, and accelerated belt wear.
The Naraku R-Vent version is distinguished by:
Ventilation openings/slots calculated to maximize internal airflow
Improved air circulation around friction surfaces
Increased heat dissipation
A robust construction adapted to centrifugal stresses
