Rekluse RadiusCX 4.0 Clutch with EXP 4.0 Disk for Kawasaki KX250, KX250F and KX250X (RMS-8904140)

Upgrade clutch performance with the Rekluse RadiusCX 4.0 Clutch, part number RMS-8904140, designed for compatible Kawasaki KX250, KX250F and KX250X motorcycles. This advanced auto-clutch system combines Rekluse engineering with an updated EXP 4.0 assembly to deliver more direct power delivery, improved durability and a more connected feel at the lever. The updated base material provides increased strength in the high-temperature environment created by modern clutch systems, helping support consistent performance during demanding riding conditions.
The internal wall bases of the EXP disk have been redesigned for greater strength and rigidity, translating to a more responsive and connected lever feel. Friction pads on the outside of the EXP disk now use the proprietary friction design found on Rekluse TorqDrive clutch plates. This design is matched to the oil-flow characteristics of the clutch pack beneath it, promoting improved cooling capability and consistent clutch operation. The result is smoother engagement and dependable performance across a wide range of riding conditions.
The EXP 4.0 wedges use rolling contact with built-in pins instead of sliding contact. By reducing friction and resistance, this updated design helps provide smoother engagement, quicker response and stronger overall power delivery. Updated engagement curve designs are engineered to better match modern motorcycle engine characteristics, while multiple wedge weights and EXP spring options provide additional tuning flexibility. The Rekluse RadiusCX 4.0 Clutch is a rider-focused performance upgrade for those seeking refined clutch control, enhanced durability and consistent operation.
