Eliminates stalling, start and stop without engaging the clutch lever Increased power transfer over OEM On the fly external adjustment Allows riders to run a gear taller, letting the suspension work better and saving energy TorqDrive clutch pack provides longer clutch life with less adjustment over time EXP 4.0 Technology The EXP disk is the magic ingredient behind the functionality and benefits of Rekluse auto clutches. About 10 years ago, Rekluse introduced an innovatively redesigned version of its revolutionary auto clutch technology with EXP 3.0. The years of racing, testing and development since have led to Rekluse&';s most refined auto clutch experience yet; Introducing EXP 4.0 No More Stalling Using principles of centrifugal force, EXP technology automatically engages and disengages the clutch based on engine RPM. With EXP, riders can start and stop without touching the clutch lever. EXP automatic clutch technology provides riders precision throttle control, maximum traction and confidence to maneuver any obstacle on the track, trail, or road. Less Arm Fatigue You don&';t have to clutch as often, which preserves your arm for longer rides. Tunable to Fit Your Riding Style Each auto clutch is optimized for each bike model as it comes from the factory, and EXP 4.0 has been developed and tested in a wide range of late-model motorcycles. However, everybody rides differently, so we made sure EXP technology can be fine tuned. We offer different spring and wedge options so riders can further adjust their clutch&';s performance. Some riders like the clutch to engage just above idle, while others like later engagement. Clutch Lever Is Still Functional At All Times It is possible to fully override the auto functionality at any time. You can pull the lever in, build RPMs, pop the clutch out and raise the front tire just like normal. Have More Fun You don&';t have to worry about covering your clutch to prevent stalls all the time. You are free to relax and enjoy the ride, having one less thing to think about.
