Vertex four-stroke pistons are forged from high-quality 2618 aluminum alloy, suited for high pressures in four-stroke engines. Vertex pistons feature a Molybdenum Disulphide (MOS2) coating on the piston skirt for break-in and reduced wear. Unique piston profiles and compression ratios are offered in A, B, C, and D sizes. This variation of 0.01mm allows for a perfect piston to cylinder fit, maximizing power and performance while reducing blow-by and oil consumption. This specific piston is a Big Bore 94mm 440cc with an 11.3:1 compression ratio.
