Piston Kit:

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 and European engine manufacturers. These Piston Kits are a first class solution to replace the original piston in your machine.

Most ProX and Wossner pistons come with a coating (depending on model). The O.E.M. style tin-coated pistons assist the wear-in process as when you first started the bike. ProX and Wossner havehas 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.

Cast piston puts engine back to standard specs without boring or replacing cylinder.
Interchanges directly with the O.E.M. parts.

The piston kit comes complete with piston, rings, wrist pin and end clips. We also supply a little end bearing with this kit.
