The Vertex Big Bore Piston Kit is designed for exceptional performance and durability, making it a reliable choice for both 2-stroke and 4-stroke engines. The pistons undergo a T-5 heat treatment and hardening process, ensuring enhanced strength and durability. The piston skirts are coated with a high-tech molybdenum disulphide coating to reduce friction, improve break-in time, and extend piston life. The 2-stroke piston kits are crafted from gravity-cast aluminum alloy containing 18% silicone, resulting in lightweight yet highly durable pistons. Meanwhile, the 4-stroke pistons are forged from 2618 aluminum for superior strength and reliability. These 4-stroke options include high-compression pistons to boost power and torque across the entire RPM range, as well as big bore pistons that increase engine displacement, torque, and peak horsepower. Each kit includes a piston, piston rings, wrist pin, and circlips for a complete installation. The piston kits are designed as OEM replacements, ensuring compatibility and reliable performance in your engine.
