Quality you can see, power you can feel—Vertex Replica piston kits are choice replacements for precision performance. Available in 2- and 4-stroke, the Replica piston kits feature both cast and forged manufacturing processes, supplying the highest quality to meet your needs. And, Vertex offers A, B, C, and D sizes, so you can choose the proper fit for your cylinder. The difference in the sizes is 0.01mm (0.0004 in.) increments, with A being the smallest and D the biggest. Vertex Replica piston kit notes: * 2-stroke piston kits are gravity cast aluminum alloy with 18 percent silicone content, which produces an extremely light but very strong piston * 4-stroke pistons are forged from 2618 or 3032 alloys for superior strength and durability * All pistons are heat-treated with a T-5 hardening and tempering cycle * All piston skirts are treated with a high-tech molybdenum disulfide (MOS2) coating for faster break-in time and increased piston life * Standard pistons and rings are OEM replacements * Kits include piston, rings, wrist pin, and circlips
