Only for certain Kawasaki models. The composition of the disc set varies depending on the motorcycles; it is necessary to measure the thickness of each of your smooth discs, and you will find the different references to order according to the desired thickness and quantity. A motorcycle's clutch is generally a multi-plate oil bath type. (Exception: for Ducati and Aprilia brands which have dry clutches). We recommend changing the disc set (friction discs and smooth discs), as well as the springs and the clutch cover gasket for better efficiency. Their replacement is simple and quick. Note: the "smooth" discs are sold individually, and you need to plan for 8 discs.
