Vertex GP Racer's Choice 4-Stroke Piston Kit for 250cc 78mm Bore

Unleash the ultimate performance in your 250cc 4-stroke engine with the Vertex GP Racer's Choice Piston Kit. Engineered for the demands of competitive racing, this kit delivers a significant boost in power, strength, and overall engine durability.

Description

The Vertex 4-Stroke Piston Kit 250cc (Standard Size B) is meticulously crafted for motorcycle enthusiasts and racers seeking uncompromising engine performance. Featuring T-box forgings and unique dome profiles, these pistons are designed to achieve increased compression ratios, translating directly into more usable power on the track or trail. Each piston is precision-forged from high-strength 2618 aluminum, renowned for its superior durability and ability to withstand extreme conditions. A rigorous T-5 hardening and tempering cycle further enhances the piston's structural integrity, ensuring long-lasting reliability.

To optimize engine efficiency and longevity, the piston skirts are treated with a high-tech Molybdenum Disulphite coating. This advanced surface treatment drastically reduces friction, facilitates a faster break-in period, and extends the overall piston life. With a precise bore size of 78.00 mm and a piston diameter of 77.96 mm, this Vertex GP Racer's Choice Piston Kit ensures an exact fit for your 250cc 4-stroke engine. The complete kit includes the piston, high-quality nitride-coated steel rings, a wrist pin, and circlips, providing everything you need for a comprehensive and reliable engine rebuild.
