Weight:0.4 kg
169-537Cooling Under Pressure: SSP-G 12-Spoke Performance Clutch Bell
Eliminate clutch fade and improve take-off consistency with the SSP-G 12-Spoke Performance Clutch Drum. Engineered for 125cc to 170cc GY6 engines, this high-performance bell features a specialized 12-spoke vented design. This open architecture drastically improves airflow within the CVT case, allowing heat to escape rapidly and preventing the clutch pads from "glazing" during aggressive stop-and-go riding or off-road use.
Technical Performance Features
- Vented 12-Spoke Design: Maximizes heat dissipation to keep clutch temperatures low, ensuring a consistent bite and preventing power-robbing slip.
- Precision Balanced: CNC-machined to exacting tolerances to eliminate high-RPM vibration, protecting your final drive bearings and ensuring a smooth power delivery.
- Enhanced Friction Surface: The internal drum surface is optimized for rapid engagement, reducing "shudder" during low-speed take-offs.
- Universal GY6 Compatibility: Features a standard 19-spline interface, making it a direct-fit upgrade for nearly all 150cc-based 4-stroke scooters, ATVs, and karts.
