PISTON KIT 78.00mm HIGH COMPRESSION 13.5:1. ProX pistons are precision machined on state-of-the-art CNC equipment using a low-expansion, low-friction piston alloy similar to that used by major Japanese engine manufacturers. These piston kits are a high-quality replacement for original pistons in motorcycles, scooters, mopeds, ATVs, and personal watercraft. Many ProX pistons feature an OEM-style tin coating to aid the break-in process and a new skirt coating that reduces friction after break-in. The black coating is made from a blend of materials to increase performance. This kit is a replacement part for PROX RING SET 02.1335.
