Description
The Vertex Top End Piston Kit features a cast piston crafted to original equipment specifications. Each piston undergoes a T-5 hardening and tempering cycle, ensuring superior strength and reliability. The piston skirt is coated with Molybdenum Disulphide, which reduces friction for faster break-in and extends piston life. Constructed from gravity-cast aluminum alloy with 18% silicone content, this piston is both lightweight and exceptionally strong. Compatible with 125cc 2-stroke engines, this kit provides the necessary components for a complete top-end rebuild. The piston and rings serve as reliable OEM replacements, ensuring optimal engine performance and longevity.
