Product Description

The Rekluse RadiusCX 4.0 Clutch Kit represents the pinnacle of automatic clutch performance for your Yamaha 2-stroke. This next-generation system features an updated EXP assembly that utilizes rolling contact technology instead of traditional sliding, significantly reducing friction and resistance.

Whether you are racing woods or clearing obstacles on the track, the RadiusCX 4.0 offers unparalleled tunability and durability, ensuring your YZ250 or YZ250X delivers consistent, race-winning performance every time you twist the throttle.

Frequently Asked Questions

Q: What makes the 4.0 version better than previous RadiusCX generations?
A: The move to rolling pins in the EXP 4.0 assembly is the biggest leap forward. It drastically reduces internal friction compared to the old sliding design, resulting in a much more responsive, connected feel and improved durability under heavy use.

Q: Can I still use my manual clutch lever?
A: Yes. The RadiusCX 4.0 still allows you full manual override, meaning you can pull the lever to clutch, shift, or start the bike at any time, providing the best of both worlds—automatic stall prevention and manual control.

Expert Pro-Tip: Because this is an auto-clutch, the "free play" at your lever is crucial for correct performance. Always use the provided free-play gain gauge to set your cable tension perfectly. If you don't maintain the correct gap, the clutch won't engage or disengage at the correct RPM, leading to premature wear.
