Yoyodyne Slipper Clutch KTM 1190 / 1290

The slipper clutch is designed to partially disengage or "slip" when the rear wheel tries to drive the engine faster than it would run under its own power. The engine braking forces in conventional clutches will normally be transmitted back along the transmission causing the rear wheel to hop, chatter or lose traction. Slipper clutches eliminate this extra loading on the rear suspension giving riders a more predictable ride and minimize the risk of over-revving the engine during downshifts. Yoyodyne slipper clutch uses ball bearings on the ramps for superior performance to the OEM ramp on ramp design.
