  • 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, Scooter, Moped, ATV, Personal Watercraft, etc.

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 they 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.
