Vertex Forged Piston Kit - 78mm Bore - 250cc - Size D - 24629D

Elevate your motorcycle's engine performance with the Vertex GP Racer's Choice 250cc 4-Stroke Piston Kit. Engineered for demanding race conditions, this high-performance piston kit delivers superior power, strength, and durability for serious riders seeking a competitive edge.

Description

This Vertex GP Racer's Choice 250cc 4-Stroke Piston Kit is meticulously designed to optimize your engine's output. Featuring advanced T-box forgings and unique dome profiles, these pistons are engineered to achieve increased compression ratios, translating directly into enhanced power and responsiveness on the track or trail. Each piston undergoes a rigorous T-5 hardening and tempering heat treatment cycle, ensuring exceptional strength and extended durability under extreme operating conditions. The robust construction utilizes premium 2618 forged aluminum alloy, a material renowned for its superior strength-to-weight ratio, making it ideal for high-performance applications. Furthermore, the piston skirts are meticulously coated with a high-tech Molybdenum Disulphite (Moly) coating. This advanced surface treatment significantly reduces friction during initial break-in, accelerating the process and contributing to a longer overall piston lifespan. Designed for a 78.00 mm bore, this standard size D piston kit is a direct fit for your 250cc 4-stroke engine, providing a reliable and powerful upgrade.
