If an item is designated as "Competition and Racing Vehicles Only", we will require a race waiver be digitally signed before an item can ship to California.

The Vertex Big Bore Piston Kit is designed to enhance engine performance by increasing displacement, torque, and peak horsepower. For two-stroke engines, the pistons are made from a gravity-cast aluminum alloy with 18% silicone content, ensuring a lightweight yet strong construction. For four-stroke engines, the pistons are forged from 2618 aluminum, offering superior strength and durability. High-compression four-stroke pistons improve power and torque across the entire RPM range. All pistons undergo a T-5 heat treatment process for added hardness and durability. The piston skirts are coated with molybdenum disulfide (MoS2) to promote faster break-in and extended lifespan. Each kit includes a piston, rings, wrist pin, and circlips. Two-stroke replacement rings are sold individually, while four-stroke rings are sold as a set.
