ProX Piston Kit 01.2314.B, 68.00mm Bore. ProX pistons are precision machined on state-of-the-art CNC equipment using a low-expansion, low-friction piston alloy, the same used by major Japanese engine manufacturers. This piston kit is a first-class solution to replace the original piston. Most ProX pistons come with a coating to assist the wear-in process. A new skirt coating helps reduce friction after wear-in. This increases performance. Replacement parts include PROX RING SET 02.2314, PROX PISTON PIN 04.1859, PROX CLIPS 05.1812. Weight: 330g.
