RadiusX is a high performance centrifugal auto clutch combining TorqDrive and EXP technologies. TorqDrive provides more clutch discs in less space, allowing for maximum performance within your bike's existing clutch footprint. You retain full control of shifting and use of your clutch lever with no compromise in power delivery.
The Rekluse is fantastic and easy to install. Tight trail riding is now very easy with no stalls. The final adjustment is pretty much trial and error but not difficult. I feel the price is high but you get what you pay for.
