ProX pistons are precision machined on the latest, state of the art CNC equipment. The same low-expansion, low-friction piston alloy is used as is used for all major Japanese engine manufacturers. ProX Piston Kits are a first class solution to replace the original piston in your Motorcycle, Scooter, Moped, ATV, Personal Watercraft, etc.

Coated for ultimate performance Most of the ProX pistons come with a coating. Our OEM style Tin coated pistons assist the wear in process when you just started the bike. We have developed a new skirt coating that not only assists the wear in process, but also helps reducing friction after the wear in. The black coating is made from a delicate mix of materials and will increase performance.
