ProX low-expansion, low-friction cast alloy pistons are precision machined on the latest, state of the art CNC equipment. The same alloy is used as is used for all major Japanese engine manufacturers. A lot of the ProX pistons are “A R T” pistons the ones fitted as standard by most of the Japanese manufactures. ProX Piston Kits are a first class option to replace the original piston in your dirtbike. All PROX Piston Kits are supplied complete with piston, piston rings, wrist Pin and a pair of clips. From 1991 on you can only use oversize piston kits if your cylinder has had a cast iron sleeve fitted.
