About Vertex 4-Stroke Pistons

• 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 0.004", allows the piston to be perfectly sized to the cylinder for maximizing power and performance while reducing blow-by and oil consumption.
• With the purchase of a premium quality piston, every Vertex piston kit contains a complete set of nitride coated or chrome plated piston rings, a fully case hardened wrist pin and circlips all at a competitive price.
