Pro-X Racing Parts Piston Kit

Part Number: 01.2427.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 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.
