Vertex Cast Race Piston Kit for 125cc 2-Stroke Engines

Elevate your motorcycle's performance with the Vertex Cast Race Piston Kit, specifically engineered for 125cc 2-stroke engines. This complete kit provides the durability and reliability needed for demanding race conditions, ensuring optimal power delivery and extended engine life.

Description

Unleash the full potential of your 125cc 2-stroke engine with the high-performance Vertex Cast Race Piston Kit. This premium piston, featuring a 54.00 mm bore, is meticulously developed with Vertex's cutting-edge technology and a race-specific shape profile to maximize power output and efficiency. Each piston undergoes a rigorous T-5 hardening and tempering cycle, significantly enhancing its strength and heat resistance, crucial for the extreme demands of racing. The piston skirt is treated with a high-tech Molybdenum Disulphite coating, ensuring a faster break-in time, reduced friction, and substantially increased piston life. Crafted from a gravity cast aluminum alloy with an impressive 18% silicone content, this piston achieves an incredibly light yet exceptionally strong structure, outperforming many standard forged pistons in specific applications. Designed for a standard compression ratio and a 53.93 mm piston diameter, this Vertex 2-stroke piston kit is a direct fit, offering a seamless upgrade for competitive riders and serious enthusiasts seeking a reliable high-performance cast piston.
