RadiusX 4.0 Clutch Assembly

The Rekluse RadiusX 4.0 Clutch is a transmission clutch group engineered to provide superior performance and rider-focused functionality for Yamaha YFZ450, YFZ450R, and YFZ450X models. This clutch features an updated EXP (expanding friction disk) assembly, utilizing a base material specifically chosen for its enhanced strength in high-temperature environments, which are critical in clutch systems. The internal wall bases have also been redesigned to improve strength and rigidity, contributing to a more connected and responsive lever feel for the rider. Further enhancing its performance, the friction pads on the outside of the EXP disk now align with the proprietary friction design found on Rekluse TorqDrive clutch plates. This integration aids in matching oil flow characteristics within the clutch pack, promoting improved cooling and consistent operation. The EXP 4.0 wedges have been re-engineered to incorporate rolling contact with built-in pins, replacing older sliding mechanisms. This rolling pin design reduces friction and resistance, resulting in smoother engagement, a more responsive feel, and ultimately, stronger power delivery. With more direct power delivery, improved durability, and rider-focused features, the RadiusX 4.0 Clutch also boasts updated engagement curve designs tailored to better match modern motorcycle engine characteristics. Riders benefit from increased tuning options, which include varying wedge weights and EXP springs, allowing for further customization to suit specific riding styles and conditions.
