Rekluse RadiusX 4.0 Clutch for Kawasaki KX250 (RMS-8304140)

Upgrade your Kawasaki KX250 with the Rekluse RadiusX 4.0 Clutch, part number RMS-8304140. This updated EXP friction disk assembly is engineered for improved strength, smoother engagement, and more consistent operation in demanding motorcycle clutch systems. Its revised base material is better suited to high-temperature environments, helping the clutch maintain dependable performance under the heat generated during aggressive riding and repeated clutch use.
The internal wall bases have been redesigned to improve strength and rigidity, translating into a more connected lever feel and enhanced rider control. On the outer face of the EXP disk, friction pads use Rekluse’s proprietary friction design, matching the oil flow characteristics of the clutch pack beneath. This promotes improved cooling capability and supports consistent clutch operation across changing riding conditions.
Rekluse EXP 4.0 wedges now use rolling contact with built-in pins rather than sliding contact. Reduced friction and resistance help provide smoother engagement, a more responsive feel, and stronger power delivery. Updated engagement curve designs are tailored to modern motorcycle engine characteristics, while multiple wedge weights and EXP spring options provide additional tuning flexibility for riders who want to refine clutch response and engagement behavior.
Designed for riders seeking direct power delivery, improved durability, and rider-focused functionality, the Rekluse RadiusX 4.0 Clutch brings advanced automatic-clutch technology to the Kawasaki KX250. The RMS-8304140 assembly is a practical performance upgrade for motocross, off-road, and other demanding applications where predictable engagement and consistent clutch control are essential.
