About this product

Description
The Vertex Top End Piston Kit features a gravity-cast aluminum alloy piston with an 18% silicone content, resulting in a lightweight yet incredibly strong component. The piston undergoes a T-5 heat treatment for enhanced hardness and durability. Its skirt is coated with Molybdenum Disulphite, which reduces friction, ensures faster break-in, and extends piston life. The kit includes a standard size C piston with a 53.96 mm diameter, specifically designed for 125cc 2-stroke engines with a 54.00 mm bore. The nitride-coated steel rings provide excellent sealing and wear resistance, maintaining optimal compression.
