With RadiusX, a high-performance auto clutch is just a clutch pack swap away. RadiusX combines TorqDrive friction disk technology with Rekluse's innovative EXP (auto clutch) disk. TorqDrive provides more clutch disks in less space, delivering high-performance auto function within the framework of the stock clutch. The RadiusX clutch prevents engine stalls so you can focus on the ride and let the auto clutch do the rest. RadiusX delivers increased power transfer over OEM and longer clutch life with less adjustment over time. Standard clutch lever function is retained and full override. Some configurations include Rekluse basket sleeves to prolong basket life. Made in the U.S.A.
