Vertex Race Piston Kit for 48.50 mm Bore

Unleash the full potential of your 2-stroke 85cc engine with the high-performance Vertex Race Piston Kit. Engineered with Vertex technology, this cast aluminum piston kit is designed for racers and enthusiasts seeking enhanced durability and optimal power delivery.

Description

This Vertex Race Piston Kit is meticulously developed to meet the rigorous demands of racing, featuring a specialized race shape profile for superior performance. Each piston undergoes a T-5 hardening and tempering heat treatment cycle, significantly increasing its strength and longevity under extreme operating conditions. The advanced Molybdenum Disulphite (Moly) coating on the piston skirts ensures a faster break-in period and substantially extends piston life by reducing friction. Crafted from a gravity cast aluminum alloy with an impressive 18% silicone content, this 48.50 mm piston delivers an exceptionally light yet robust component, crucial for high-revving 2-stroke engines. The kit maintains a standard compression ratio and includes everything needed for a complete installation: the piston, high-quality nitride coated steel rings, a wrist pin, and circlips, ensuring a precise fit and reliable operation for your 85cc engine.
