About this product
Upgrade your two-stroke engine with the Vertex Top End Piston Kit, featuring a cast replica piston designed for optimal performance and durability. This kit provides a cost-effective solution for rebuilding your top end, delivering reliable power and extended engine life.
Description
The Vertex Top End Piston Kit is engineered as an OEM replacement, providing exceptional value and performance. Crafted from gravity-cast aluminum alloy with an 18% silicone content, this piston achieves an ideal balance of lightweight design and robust strength. The piston undergoes a T-5 heat treatment, enhancing its hardness and resistance to wear. A Molybdenum Disulphide coating is applied to the piston skirt, ensuring a faster break-in period and minimizing friction for increased piston longevity. This kit is designed for easy installation and compatibility with your 125cc two-stroke engine.
