Motorcycle clutch is comprised of center, the center of the product on set has, in turn, overlapping arrangement of friction plate and sheet steel, the center of the set of products including center set of ontology and through the die casting technology and sets of ontology into the integration of the internal spline sets, internal spline set made of alloy steel products; Products still set on the center of the set of several oil hole, the product of the oil hole on axis of center of spiraling arrangement on the center set. This motorcycle clutch, its oil hole spiraling arrangement on the center set, make in the process of clutch, the friction plate can fully contact with lubricating oil, the friction plate and sheet steel rapid separation thoroughly, can eliminate the clutch binding problem, power can quickly cut off; And by spline set in the center set of ontology set on insert, internal spline torque capacity and wear-resisting performance is better, can eliminate internal spline of the wear and fracture problem, longer service life of the clutch.

Motorcycle engine clutch include operating arm, pipe run, push rod and the pressure plate, plunger, sliding products is set in the product guide tube, its characteristics is the product of the guide tube is set to axial moving the ball along the pipe run and adjust screw, products of steel ball in between the plunger and product adjustment screw, and both sides of the ball with one end of the push rod, one end of the adjusting screw close contact, the other end of the adjusting screw out pipe mouth of the pipe run out side through adjustments of the adjustment screw nut, lock nut and product pressure plate is fixed. This product by adjusting the separation of the clutch travel, prevent because of the separation of the clutch is not complete and affect the engine operation, to extend the motorcycle gearshift, shifting fork and the service life of the gear, and raised the motorcycle driving safety.
