Vertex four-stroke pistons are forged from high-quality 2618 aluminum alloy. They are designed to handle the demands of modern four-stroke engines. Vertex pistons feature a Molybdenum Disulphide MOS2 coating on the piston skirt to aid in break-in and reduce wear. Vertex pistons are available in A, B, C, and D sizes, with variations of 0.004 inches, to ensure a precise fit within the cylinder. This precise sizing maximizes power and performance while reducing blow-by and oil consumption. This piston has a bore size of 99.95mm and a standard compression ratio of 9.9:1.
