Pro-X Racing Parts
Part Number 01.6413.B
- 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 reducing 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.
