NCY Racing Clutch Bell (Star); Yamaha Zuma 125 2022+

The NCY Racing Clutch Bell (Star) is a performance replacement for the 2022+ Yamaha Zuma 125, featuring a star-profile inner drum designed to improve clutch shoe engagement and reduce heat buildup under aggressive riding conditions. The clutch bell is the outer housing of the centrifugal clutch assembly — as engine RPM rises, the clutch shoes expand outward and contact the inner surface of the bell, transferring power to the rear wheel. The star-profile geometry increases the effective contact surface area, promoting more progressive engagement and better heat dissipation compared to a standard smooth-bore bell, making it well-suited for performance-oriented setups and stop-and-go urban riding alike.

• Star-profile inner drum for improved clutch shoe contact and heat dissipation
