Rekluse auto clutch systems use proprietary EXP technology to enable riders to stop and start in gear without using the clutch lever, virtually eliminating stalling. A Rekluse RadiusX auto clutch can help provide a competitive advantage or just enhance your riding experience. A RadiusX clutch provides automatic engagement, prevents stalling, reduces clutch fade and gives a less aggressive, smoother feel and still maintains full clutch lever use.
