Yoyodyne Slipper Clutch

[RidersDiscount]

Yoyodyne motorcycle parts are synonymous with quality and performance and Yoyodyne slipper clutches are no exception. Their precision build and wide breadth of adjustability that require no special tools for adjustments make them a popular choice for everyone from club racers to AMA Pro teams.  

 

Yoyodyne clutches are assembled using fewer parts than other aftermarket slipper clutches, so there’s less to fail and is what ultimately makes them easier to work on in the first place. A simple, smooth-acting ramp mechanism within the clutch hub provides slip when rear wheel and engine speed don’t match. This simple mechanism allows the rider to concentrate on corner entry at maximum speed without having to wait for the rear end of the bike to calm down leading to increased rider confidence and lower lap times. Many late model motorcycles come from the factory with OEM slipper clutches installed but they lack the kind of adjustability that a Yoyodyne slipper clutch provides.

Each slipper clutch is developed with the aid of professional riders for each application, giving you a setup that’s in the ballpark straight out of the box for most riders. 

 

 

Unlike other aftermarket clutch manufacturers and some OEM slipper clutches, Yoyodyne slipper clutches do not use proprietary diaphragm type springs. As a result, they provide a better, more linear feel when starting off the line. Modulation is easier thanks to their more consistent clutch engagement.  Yoyodyne also includes two sets of spring retainer buttons with two different thicknesses. This allows any rider to fine-tune his machine to his needs.

To prevent clutch plates from overheating, oil passages are machined into the sides of the clutch hub. Oil entering through the center is evenly distributed throughout for consistent operation in the high-stress environment of a racing engine.  Yoyodyne clutches use a much tougher base plate of the clutch hub to limit clutch slip. This reduces stress on spring retention bolts that weren’t designed to tolerate lateral loads in the first place, increasing reliability.
