The Vertex Piston Kit offers high-quality replacement pistons for both 2-stroke and 4-stroke engines. - **2-Stroke Pistons**: Made from gravity-cast aluminum alloy with 18% silicone content, ensuring a lightweight yet strong design. - **4-Stroke Pistons**: Forged from 2618 aluminum for enhanced strength and durability. The high-compression versions improve power and torque across the entire RPM range, while big-bore options increase engine displacement, torque, and peak horsepower. All pistons undergo a T-5 heat treatment process for added durability. The piston skirts are coated with molybdenum disulfide (MoS2) to reduce friction, provide a faster break-in period, and extend piston life. Each kit includes a piston, rings, wrist pin, and circlips. Replacement rings for 2-stroke pistons are sold individually, while 4-stroke piston rings are sold as complete sets.
