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. Comprehensive Fitment Guide This performance bell is a direct-fit upgrade for Yamaha 125cc scooters using a 129mm clutch system: Model Series Compatibility Note Yamaha Zuma 125 All Years (BWS 125 \/ YW125) Yamaha Vino 125 All Years Yamaha Cygnus X 125 Fits various 4-valve 125cc chassis Technical Specifications Inner Diameter: 120mm Outer Diameter: 129mm Spline Count: 16-Spline Finish: PTFE Non-Stick Performance Coating Manufacturer: NCY (ISO 9001 Certified) Mechanic's Note: When upgrading to a racing bell, we highly recommend inspecting your clutch shoes for glazing.
