ProX piston kit, 82cc, 47.50 mm bore. 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. This kit is a first-class solution to replace the original piston. Many ProX pistons feature a tin coating to assist the wear-in process and a new skirt coating to reduce friction after wear-in. The black coating is made from a delicate mix of materials to increase performance. Replacement parts include PROX RING SET 02.1113, PROX PISTON PIN 04.1439, and PROX CLIPS 05.1410C. This is a ProX 01.1113.B piston kit.
