PROX PISTON KIT

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.

Coated for ultimate performance

Most of the ProX pistons come with a coating. ProX OEM style Tin coated pistons assist the wear in process when you just started the bike. They 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.

Note: Please ensure you have measured and selected the correct size piston.
