ProX piston kits are a first class solution to replace the original piston in your motorcycle. Coated For Ultimate Performance Most of the ProX pistons come with a coating. The OEM style Tin coated pistons assist the wear in process when you have 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.
