Vertex OE Replica Cast Piston is a popular choice for OE replacement, crafted from a gravity-cast aluminum alloy with 18% silicone content. The piston is heat treated with a T-5 hardening and tempering cycle for improved strength and durability. Additionally, the piston skirt is coated with a high-tech Molybdenum Disulphite coating for a faster break-in time and extended lifespan. With these factors in mind, this piston is an ideal choice for your bike's engine.
