PISTON KIT 78.00mm STD COMPRESSION 12.9:1. ProX pistons are precision machined on the latest CNC equipment using the same low-expansion, low-friction piston alloy used by major Japanese engine manufacturers. ProX Piston Kits are a first-class solution to replace the original piston in your Motorcycle, Scooter, Moped, ATV, or Personal Watercraft. Most ProX pistons come with an OEM-style Tin coating to assist the wear-in process. A new skirt coating has been developed that assists the wear-in process and reduces friction after wear-in. The black coating increases performance. Replacement parts include PROX RING SET 02.1335, PROX PISTON PIN 04.1641.5, and PROX CLIPS 05.1612. Part number 01.1338.A. Manufacturer: Pro-X Racing.
