PROX piston kits are a first class solution to replace the original piston in your motorcycle, scooter, moped, ATV, personal watercraft, etc. PROX piston kits for sleeved cylinders are available in standard size and a wide range of oversizes. The availability of oversizes up to 2mm significantly helps to increase the lifespan of a cylinder by offering more re-boring possibilities.
