Rekluse RadiusCX 4.0 Clutch for Honda CRF450R/RX (RMS-8901009)

Upgrade clutch performance on your Honda CRF450R or CRF450RX with the Rekluse RadiusCX 4.0 Clutch, part number RMS-8901009. This updated EXP assembly is engineered to provide more direct power delivery, improved durability, and a more connected lever feel for demanding motocross, off-road, and high-performance riding applications. The base material has been strengthened for better resistance to the high temperatures generated by modern clutch systems, helping support consistent operation during extended or aggressive use.
The internal wall bases have been redesigned for increased strength and rigidity, allowing the clutch to deliver a more precise and connected feel through the lever. On the outside of the EXP disk, friction pads use Rekluse’s proprietary friction design, matching the technology found in Rekluse TorqDrive clutch plates. This design helps align oil-flow characteristics with the clutch pack beneath, promoting improved cooling capability and reliable clutch performance across changing operating conditions.
The RadiusCX 4.0 also features updated EXP 4.0 wedges with built-in pins that create rolling contact instead of sliding contact. Reducing friction and resistance helps provide smoother engagement, a more responsive feel, and stronger overall power delivery. Updated engagement-curve designs are tuned to better complement the characteristics of modern motorcycle engines, while multiple wedge weights and EXP spring options provide additional tuning flexibility. Designed specifically for compatible Honda CRF450R and CRF450RX models, the Rekluse RMS-8901009 delivers rider-focused clutch functionality for improved control and performance.
