Rekluse RMS-8901102 RadiusCX 4.0 auto clutch kit 21-24 CRF450R CRF450Rx


Rekluse Radius CX 4.0 Clutch Kit Honda CRF450R / RX / RWE 

Redefining the off-road clutch game yet again, Rekluse has stepped it up with some game changing improvements to their 3.0 EXP auto-clutch system. This kit takes all of the awesomeness from the previous generation Radius CX and adds the next-generation 4.0 EXP auto-clutch for improved torque, smoothness and longevity. Using the same friction material pattern as the TorqDrive clutch plates, the EXP 4.0 matches oil-flow characteristics of the drive plates underneath which improves cooling and allows for consistent operation. 

The core component of Rekluse's famous auto clutch is the wedges, that move outwards under centrifugal lode and engage the clutch pack - the 4.0 design incorporates bearing-style roller pins that roll as the wedges move outward, providing a smoother engagement and less friction - which means less heat, and better overall clutch performance.

If you haven't ridden with a Rekluse yet, prepare for a world without stalling, smoother power delivery and an extreme level of confidence.
