About this product
Upgrade your two-stroke engine with the Vertex Top End Piston Kit, designed as a cast replica of the original OE piston. This kit delivers reliable performance and extended engine life. Ideal for enthusiasts and professionals seeking quality and durability.
Description
The Vertex Top End Piston Kit provides a cost-effective solution for rebuilding your engine's top end. The piston is cast from gravity-cast aluminum alloy with 18% silicone content, ensuring a lightweight yet robust design. Each piston undergoes a T-5 heat treatment, hardening and tempering cycle for enhanced strength. The piston skirt features a Molybdenum Disulphite coating, reducing friction and promoting faster break-in times while extending piston life. This kit is designed to meet or exceed OEM specifications, offering a seamless fit and optimal performance for your 85cc 2-stroke engine.
