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.
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. ProX 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.
All ProX Piston Kits are supplied complete with Piston Rings, Wrist Pin and Circlips, ready to install!
