NCY Racing Clutch Bell (PTFE Star): Zuma & Vino 125

Elite Performance: NCY PTFE-Coated "Star" Racing Clutch Bell Eliminate clutch slip and unlock faster acceleration with the NCY Racing Clutch Bell . Engineered for the Yamaha 125cc platform, this "Star" series bell is the lightest option on the market. By significantly reducing rotational mass compared to the heavy OEM drum, your engine reaches its powerband faster, resulting in crisper throttle response and reduced strain on your drive belt. Technical Performance Features Advanced PTFE Coating: The specialized "Star" coating provides superior heat dissipation and high-friction contact, virtually eliminating the "clutch shudder" common in stop-and-go city riding. Lightweight Rotational Design: Minimizing centrifugal mass allows the engine to rev up quicker, providing a noticeable boost in "off-the-line" sprinting and mid-range recovery. Sandblasted Internal Surface: The inner drum features a precision-grooved surface that allows the clutch pads to "bite" instantly, reducing friction-induced heat and extending the life of your clutch shoes. Enhanced Cooling Vents: The iconic star-shaped cutouts act as centrifugal fans, pulling cool air through the transmission case to prevent glazed pads and belt fade.
