The EBC DRC kit is the best way to reset your bike's clutch to the exact as new standard sizing. Replacing just the plates can work but new clutch springs are always better and springs get tired and cause slippage, plus the separator steel plates from EBC are pin-planished, forming tiny indents in the steel which improves the spread of oil around the clutch surfaces.
