Vertex Four-stroke Pistons (BIG BORE)
When it comes to power and performance, Vertex four-stroke pistons are hard to beat. Forged from the highest quality 2618 aluminium alloy, Vertex pistons are perfectly suited to handle the rigors and high pressures of today's modern four-stroke engines. Plus, to aid in the break-in process and reduce wear, every Vertex piston utilizes a unique Molybdenum Disulphide (MOS2) coating on the piston skirt.
But, what truly sets Vertex 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 sizing, a mere 0.01mm, allows the piston to be perfectly sized to the cylinder for maximizing power and performance while reducing blow-by and oil consumption.
Vertex pistons are made from cast aluminium (not forged) with an 18-20% silicone content which gives you a light but strong piston. Piston skirts are bisulphide coated for faster break-in time and increased piston life. All pistons are heat treated with T-5 hardening and tempering cycle.
