REKLUSE RadiusX 4.0 Clutch for Kawasaki KX450 – Part RMS-8304047

The REKLUSE RadiusX 4.0 Clutch (Part RMS-8304047) is engineered to enhance performance and durability for Kawasaki KX450 motocross bikes. Featuring an updated EXP (expanding friction disk) assembly, this clutch incorporates a high-strength base material designed to withstand high-temperature environments typical of aggressive riding conditions. The redesigned internal wall bases contribute to increased strength and rigidity, resulting in a more direct and connected lever feel that improves rider control and confidence during intense riding sessions.
Friction pads on the outside of the EXP disk now utilize a proprietary friction design similar to the Rekluse TorqDrive clutch plates, optimizing oil flow beneath the clutch pack. This innovation enhances cooling efficiency and maintains consistent clutch operation, reducing heat-related issues and extending component lifespan.
The EXP 4.0 wedges have been upgraded to include rolling contact with built-in pins, replacing sliding contact to lower friction and resistance. This change delivers smoother engagement, a more responsive feel, and stronger power transfer, ultimately providing a more seamless riding experience. The clutch's engagement curve has been fine-tuned to better match modern motorcycle engine characteristics, ensuring optimal power delivery and control.
Additional tuning options are available through different wedge weights and EXP springs, allowing riders to customize clutch feel and performance to their preferences. Overall, the REKLUSE RadiusX 4.0 Clutch offers improved durability, more precise power transfer, and rider-focused functionality, making it an ideal upgrade for serious motocross enthusiasts seeking reliability and high performance.
