Eliminate mid-range transmission slipping and rough takeoff shudder with the premium NCY Performance Lightened Clutch Bell . Engineered specifically as an upgraded replacement for 125cc to 170cc 4-stroke CVTs, this bell features a lightened housing that allows your engine to rev up faster into its peak power band while reducing parasitic rotational mass compared to heavy OEM components. Engineered for high-stress urban commuting and performance tuning, the internal drum surface features a specialized light texture that provides maximum friction bite. This prevents glazing under intense heat and optimizes transmission engagement. Product Features Lightened Rotor Profile: Reduces inertial mass for faster RPM spooling and crisper throttle response off the line. Cross-Drilled Ventilation: Precision-milled cooling ports rapidly dissipate operational heat and allow centrifugal dust debris to escape the clutch assembly. Anti-Glaze Textured Interior: Mildly knurled friction lining ensures immediate clutch pad bite, eliminating common shuddering loops. Heavy-Duty Forged Steel: Rigid, distortion-resistant outer ring prevents the bell from expanding or warping under high thermal strain or racing loads.
