Vertex GP Racer's Choice 4-Stroke Piston Kit 78.00mm Bore

Elevate your motorcycle's performance with the Vertex GP Racer's Choice 4-Stroke Piston Kit. Engineered for superior power, strength, and durability, this kit is the ultimate upgrade for serious riders.

Description

The Vertex GP Racer's Choice 4-Stroke Piston Kit is meticulously engineered for motorcycle enthusiasts demanding peak performance. Each forged piston is crafted from high-strength 2618 aluminum, ensuring exceptional durability and superior strength under extreme racing conditions. Designed with unique dome profiles and T-box forgings, this 78.00mm bore piston kit delivers increased compression ratios to generate more power and responsiveness from your 250cc engine. A critical T-5 hardening and tempering cycle enhances the piston's structural integrity, while a high-tech Molybdenum Disulphite (Moly) coating on the piston skirts significantly reduces friction. This advanced coating promotes faster break-in times and extends piston life, making it a reliable choice for competitive racing and demanding rides. The kit provides all necessary components for a complete installation, including the piston, rings, wrist pin, and circlips, ensuring a hassle-free upgrade.
