About Vertex 4-Stroke Pistons

Vertex pistons are designed for riders who demand maximum power, durability, and precision from their 4-stroke engines.

• Forged for Strength: Made from high-quality 2618 aluminum alloy, Vertex pistons are built to withstand the extreme pressures of modern 4-stroke engines.
• Advanced MOS2 Coating: A unique Molybdenum Disulfide coating on the piston skirt aids the break-in process, reduces friction, and minimizes wear for longer piston life.
• Precision Fitment: Available in A, B, C, and D sizes (with only 0.004” variation), these pistons are perfectly matched to your cylinder to maximize power, reduce blow-by, and minimize oil consumption.
• Complete Piston Kit: Each kit includes nitride-coated or chrome-plated piston rings, a fully case-hardened wrist pin, and circlips—all at a competitive price.
