Rekluse RadiusX 4.0 Clutch for Kawasaki KX250F 2009-2020 RMS-8304040

If you're pushing your KX250F to its limits on the track or trail, clutch responsiveness directly impacts your lap times and control. The Rekluse RadiusX 4.0 replaces vague, delayed engagement with precise, instantaneous power delivery—giving you the confidence to attack corners and accelerate out of them without second-guessing your machine. Built with redesigned internals and proprietary friction compounds, this clutch system handles the heat and aggression that modern 4-stroke racing demands.

What sets the RadiusX 4.0 apart is its engineered balance between durability and feel. The improved EXP assembly uses high-temperature materials that survive sustained abuse, while the redesigned internal walls provide the crisp lever feedback that separates good clutch systems from great ones. Rolling-contact pins reduce friction losses, meaning more of your throttle input translates directly to wheel drive—no dead zone, no mushy engagement.

Rekluse designed the friction pads to work seamlessly with their TorqDrive clutch plates, optimizing oil flow and cooling under load. The result is a tunable system that lets you dial in wedge weights and EXP springs to match your riding style, track conditions, and engine setup. Whether you're a weekend warrior or podium hunter, this clutch adapts to how you ride.
