Eliminate drivetrain slip and maximize power transfer with the premium RDR Performance Vented Clutch Drum. Engineered as a high-performance upgrade for standard 125cc and 150cc 4-stroke GY6 engine platforms, this clutch bell is structurally optimized to solve the common overheating, glazing, and shuddering issues found in stock commuter setups.
The interior contact wall features an advanced, friction-enhanced surface treatment that allows your clutch pads to bite hard and immediately upon engagement. Combined with a precision-balanced, multi-window vented outer chassis, this drum rapidly channels away clutch dust and operational heat, keeping your CVT system running cool even under aggressive stop-and-go urban riding or track-level stress.
Product Features
- Vented Heat-Dissipation Windows: Strategically machined perimeter cutouts dramatically increase airflow, cooling internal pads and preventing thermal glazing.
- Friction-Enhanced Inner Surface: Specialized internal textured wall provides a superior abrasive bite, eliminating off-the-line engine shudder and clutch slip.
- Dynamic Spin Balancing: Precision computer-balanced during manufacturing to eliminate high-RPM vibrations and protect your rear input shaft bearings.
- Lightweight Structural Design: Sheds unnecessary rotating mass compared to dense factory castings, promoting faster throttle response and smoother spooling.
