REKLUSE RadiusCX 4.0 Clutch for CRF450R/X RMS-8901012 – Enhanced High-Temperature Performance and Smoother Engagement

The REKLUSE RadiusCX 4.0 Clutch (Part Number RMS-8901012) is engineered to provide superior clutch performance for high-performance motocross bikes like the CRF450R and CRF450X. Featuring an updated EXP (expanding friction disk) assembly, this clutch delivers improved durability and strength in demanding high-temperature environments, essential for sustained racing and aggressive riding conditions. The base material has been upgraded to enhance heat resistance, ensuring consistent operation during extended sessions. Internal wall bases are redesigned for increased strength and rigidity, translating to a more connected and precise lever feel for the rider, which improves control and confidence on the track.

Outside, the friction pads have been matched to the proprietary friction design found on Rekluse TorqDrive clutch plates. This design promotes optimal oil flow beneath the clutch pack, aiding in efficient cooling and preventing overheating. The EXP 4.0 wedges now incorporate rolling contact with built-in pins, reducing friction and resistance compared to sliding contact. This modification results in smoother engagement, quicker throttle response, and stronger power transfer, enhancing overall riding performance. The updated engagement curve is tailored to better align with modern motorcycle engine characteristics, providing more direct power delivery and improved durability.

Designed with rider control and tuning flexibility in mind, the REKLUSE RadiusCX 4.0 offers additional options through varying wedge weights and EXP springs. These features allow riders to fine-tune clutch engagement and performance to match their riding style and track conditions. Whether racing or trail riding, this clutch system provides reliable, consistent operation with a focus on durability, heat management, and responsiveness. The REKLUSE RadiusCX 4.0 Clutch is a significant upgrade for riders seeking enhanced performance, smoother operation, and longer-lasting clutch components.
