REKLUSE RadiusCX 4.0 Clutch for Yamaha RMS-8907070 – High-Performance Expanding Friction Disk Assembly

The REKLUSE RadiusCX 4.0 Clutch for Yamaha RMS-8907070 delivers improved strength, durability, and rideability for modern motocross and off-road motorcycles. Featuring an updated EXP (expanding friction disk) assembly, this clutch is engineered with a high-temp resistant base material that ensures reliable performance in demanding heat environments. The internal wall bases have been redesigned for increased strength and rigidity, translating into a more connected and responsive lever feel for the rider, enhancing control during aggressive riding situations.
The outer friction pads on the EXP disk now incorporate a proprietary friction design similar to that found on REKLUSE's TorqDrive clutch plates. This design promotes better oil flow beneath the clutch pack, resulting in improved cooling and more consistent operation under heavy load. The EXP 4.0 wedges have been upgraded to feature rolling contact with built-in pins, reducing friction and resistance compared to sliding contact. This change provides smoother engagement, quicker throttle response, and stronger power transfer, all contributing to a more direct and predictable power delivery.
Designed with rider-focused functionality, the REKLUSE RadiusCX 4.0 offers updated engagement curves that better match modern motorcycle engine characteristics. This allows for a more seamless integration of clutch engagement with engine power, improving overall handling and rider confidence. Additionally, the clutch system provides more tuning options with various wedge weights and EXP springs, enabling riders to customize the feel and performance to suit their riding style and terrain preferences.
Constructed for durability and performance, the REKLUSE RadiusCX 4.0 Clutch is an essential upgrade for riders seeking reliable, high-quality clutch performance that enhances control, power transfer, and cooling efficiency. Whether racing or trail riding, this clutch assembly offers a significant upgrade over stock components, ensuring consistent operation in the most demanding conditions.
