- ProX pistons are precision machined on the latest, state-of-the-art CNC equipment.

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 reduce friction after the wear in. The black coating is made from a delicate mix of materials and will increase performance. The latest cylinders are plated by a Nicasil plating.
