Vertex pistons are forged from 2618 aluminum alloy, designed for high pressure four-stroke engines. Each piston features a Molybdenum Disulphide MOS2 coating on the piston skirt to aid break-in and reduce wear. Vertex offers unique piston profiles and compression ratios in A, B, C, and D sizes. This sizing variation of 0.004 inches allows for a precise fit to the cylinder, maximizing power and performance while reducing blow-by and oil consumption. This is a 100mm 500cc Big Bore piston.
