REKLUSE RadiusCX 4.0 Clutch for CRF450R/RX – Part RMS-8901009

The REKLUSE RadiusCX 4.0 Clutch (Part RMS-8901009) offers advanced performance enhancements designed for high-performance motocross and off-road riding. Featuring an updated EXP (expanding friction disk) assembly, this clutch utilizes a new base material that provides superior strength in high-temperature environments typical of heat clutch systems. This ensures reliable operation even under strenuous conditions. The internal wall bases have been redesigned to enhance strength and rigidity, translating into a more connected and precise lever feel for the rider, which improves control during aggressive riding sessions. On the exterior, the friction pads now incorporate a proprietary friction design similar to that found on Rekluse TorqDrive clutch plates, a feature that optimizes oil flow characteristics beneath the clutch pack. This design promotes better cooling and consistent clutch operation, reducing heat buildup and prolonging component life. The EXP 4.0 wedges have been upgraded to utilize rolling contact with built-in pins, replacing sliding contact. This reduces friction and resistance during engagement, resulting in smoother clutch operation, quicker response, and stronger power delivery. These improvements lead to more direct power transfer, increased durability, and a rider-focused feel that enhances overall performance. The engagement curve has been fine-tuned to better match modern motorcycle engine characteristics, offering more precise control for aggressive riding styles. Additionally, the clutch provides more tuning options with a variety of wedge weights and EXP spring configurations, allowing riders to customize their setup for optimal performance. Whether used in competitive racing or demanding trail riding, the REKLUSE RadiusCX 4.0 Clutch ensures reliable, consistent, and responsive clutch engagement, making it a valuable upgrade for serious motocross enthusiasts.
