Vertex Cast BigBore Piston Kit for 2-Stroke 250cc Engines

Unleash the full potential of your 2-stroke 250cc engine with the Vertex Cast BigBore Piston Kit. Engineered for performance and durability, this piston kit provides a significant boost in displacement, torque, and peak horsepower, ensuring your ride delivers exhilarating power when you need it most.

Description

Designed as a direct replacement in original OE form for big bore cylinders, the Vertex Cast BigBore Piston Kit is meticulously crafted from a high-quality, gravity-cast aluminum alloy with an 18% silicone content. This unique composition results in an exceptionally light yet remarkably strong piston, ideal for the demanding conditions of motorcycle engines. Each piston undergoes a rigorous T-5 hardening and tempering cycle, a specialized heat treatment that dramatically enhances its overall strength and resilience against wear and tear.

To further extend piston life and optimize break-in time, the skirts are coated with an advanced Molybdenum Disulphite finish. This high-tech coating reduces friction and wear, promoting smoother operation and sustained performance over countless miles. With a precise bore size of 67.50 mm and a +1.10 mm piston size, this kit is perfectly suited for 2-stroke 250cc engines, maintaining a standard compression ratio while delivering increased displacement. The included piston rings feature a robust Nitride Coated, Steel, and Cast material construction, ensuring reliable sealing and long-lasting operation for your high-performance piston.
