Piston Kits

Vertex

Vertex Piston Kits When it comes to power and perforance, Vertex 4 stroke pistons are hard to beat. Forged to the highest quality 2618 aluminium alloy, Vertex pistons are perfectly suited to handle the rigors and high pressures of todays modern 4-stroke engines. To aid in the break-in process, and reduce wear, Vertex pistons utilizes a unique Molybdenum Disulphide (MOS2) coating on the piston skirt. What really sets Vertex pistons apart from the competition are the unique piston profiles and compression ratios that are offered in A, B, C and D sizes. This variation in the sizing, a mere 0.004”, allows the piston to be perfectly sized to the cylinder for maximizing power and performance while reducing blow-by oil consumption.
