Yoyodyne's T16803 Slipper Clutch is made specifically for Yamaha YZF-R1 (2007-2008).
The slipper clutch prevents and/or reduces rear wheel hop when entering a turn. Our slipper clutch features a Ceramic coated pressuer plate for longer wear, the clutch spring pockets are elongated for better feel, and the pressure plate is vented and ducted to help the clutch run cooler.
The function of the slipper clutch is to reduce the pressure on the clutch pack when the engine is in the process of turning the engine. In the case of road racing type slipper clutches, there is no effect on clutch engagement when the engine is in the process of driving the real wheel. During the process of slowing for a turn (Engine Braking) the action of the torque forces the ramps together; the ramps then proceed to ride up on each other, an action which lifts the splined part of the hub off the base.
Upgraded slipper clutch to replace original one on the R1. This light weigh aluminum clutch reduces rotational mass for better acceleration, and provides a smoother slip on corner entry and clutch re-engagement. Replaces clutch on Yamahas that use part number 4C8-16360-00-00.
