Vertex Cast Race Piston Kit for 85cc 2-Stroke

Elevate your engine's performance with the Vertex Cast Race Piston Kit, specifically engineered for 85cc 2-stroke motorcycles. This high-performance piston kit is designed to meet the rigorous demands of racing, offering superior durability and a quicker break-in period.

Description

The Vertex Cast Race Piston Kit is the ultimate upgrade for your 85cc 2-stroke engine, combining cutting-edge Vertex technology with a race-proven profile. Each piston undergoes a meticulous T-5 hardening and tempering cycle, significantly enhancing its strength and resistance to wear under extreme conditions. Crafted from a gravity cast aluminum alloy with an impressive 18% silicone content, this piston achieves an exceptional balance of lightness and structural integrity, ensuring reliable performance without added bulk. The piston skirts are precision-coated with a high-tech Molybdenum Disulphite (Moly) layer, which not only accelerates the break-in process but also substantially extends piston life by reducing friction. With a precise 47.00 mm bore and a piston diameter of 46.94 mm, this standard size A kit ensures a perfect fit. The kit includes everything needed for a comprehensive piston replacement: the high-quality cast piston, durable nitride coated steel rings, a robust wrist pin, and secure circlips. Experience optimized power delivery and extended engine life with this expertly designed motorcycle race piston.
