REKLUSE RadiusCX 4.0 Clutch for CR250R/500R – Part RMS-8901021

The REKLUSE RadiusCX 4.0 Clutch, part number RMS-8901021, is engineered to enhance performance and durability for high-performance motocross and off-road bikes like the CR250R and 500R. This clutch assembly features an updated EXP (expanding friction disk) design with a new base material that offers superior strength and heat resistance, ensuring reliable operation even in demanding high-temperature environments. The internal wall bases have been redesigned for increased strength and rigidity, which translates into a more connected lever feel for the rider, improving control during aggressive riding scenarios.
On the exterior of the EXP disk, friction pads now utilize a proprietary friction design aligned with Rekluse TorqDrive clutch plates. This design optimizes oil flow beneath the clutch pack, enhancing cooling efficiency and maintaining consistent clutch operation. The EXP 4.0 wedges have been upgraded to incorporate rolling contact with built-in pins, reducing friction and resistance compared to sliding contacts. This improvement results in smoother engagement, more responsive power delivery, and increased overall durability.
The clutch’s engagement curve has been fine-tuned to better match modern motorcycle engine characteristics, providing a more intuitive and predictable feel for the rider. Additionally, the design allows for greater tuning flexibility with different wedge weights and EXP springs, enabling riders to customize their clutch response based on their riding style and needs. Whether for aggressive motocross racing or demanding trail riding, the REKLUSE RadiusCX 4.0 delivers direct power transfer, improved durability, and a refined riding experience, making it an excellent upgrade for serious riders seeking reliable performance and precise control.
