About this product
Upgrade your 125cc 2-stroke engine with the Vertex Top End Piston Kit, designed for racing performance and superior durability. This kit delivers enhanced power and reliability, ensuring optimal engine performance under demanding conditions. Get the most out of your machine with Vertex's leading piston technology.
Description
The Vertex Top End Piston Kit features a forged piston crafted from 2618 aluminum alloy, offering exceptional strength and resistance to wear. Each piston undergoes a T-5 hardening and tempering cycle, further enhancing its durability and performance. The piston skirt is coated with a high-tech Molybdenum Disulphide coating, which reduces friction for faster break-in times and extends piston life. This top end kit includes everything needed for a complete installation: piston, rings, wrist pin, circlips, and top end gaskets. Specifically designed for 125cc 2-stroke engines, the Vertex piston kit offers improved compression and efficient combustion, leading to noticeable gains in throttle response and overall power. Whether you're on the track or trail, this kit provides the reliability and performance you need to stay ahead.
