Rekluse RadiusCX 4.0 Clutch for Kawasaki KX450F (RMS-8904044)

Upgrade your Kawasaki KX450F with the Rekluse RadiusCX 4.0 Clutch, part number RMS-8904044. This advanced auto-clutch assembly is engineered to deliver more direct power transfer, smoother engagement, improved durability, and a more connected lever feel. Its updated EXP friction disk assembly uses a stronger base material designed to withstand the high temperatures generated by performance clutch systems, helping support reliable operation during demanding rides.
The redesigned internal wall bases add strength and rigidity to improve lever feedback and clutch control. On the outside of the EXP disk, friction pads feature Rekluse’s proprietary friction design found on TorqDrive clutch plates. The pad design helps match oil-flow characteristics within the clutch pack, promoting improved cooling and more consistent performance across changing riding conditions.
The Rekluse EXP 4.0 wedges now use rolling contact with integrated pins rather than sliding contact. This reduces friction and resistance during engagement, helping provide smoother operation, a more responsive feel, and stronger power delivery. Updated engagement-curve designs are optimized for modern motorcycle engine characteristics, allowing the clutch to respond naturally to engine speed and rider input.
The RadiusCX 4.0 also offers additional tuning flexibility through selectable wedge weights and EXP springs. These options allow riders and technicians to tailor engagement behavior to riding style, terrain, and performance requirements. Built for riders seeking dependable auto-clutch performance with enhanced control and durability, the Rekluse RadiusCX 4.0 Clutch combines refined engagement technology with practical tuning capability for the Kawasaki KX450F.
