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

Elevate your engine's performance with the Vertex 125cc Cast Race Piston Kit, engineered for demanding 2-stroke applications. This complete kit provides everything needed for a robust and reliable engine rebuild, ensuring peak power and extended durability.

Description

The Vertex Cast Race Piston Kit is meticulously developed using advanced Vertex technology and a race-specific profile to optimize power delivery and reliability in high-performance 2-stroke engines. Each piston, with a precise 53.95 mm diameter and 54.00 mm bore size, is gravity cast from a high-quality aluminum alloy containing 18% silicone. This unique composition delivers an exceptionally light yet remarkably strong piston, ideal for the rigors of racing and aggressive riding. To further enhance its resilience, every piston undergoes a T-5 hardening and tempering heat treatment cycle, significantly boosting its structural integrity and resistance to wear. The skirt of each piston is finished with a high-tech Molybdenum Disulphite coating. This advanced coating not only facilitates a quicker break-in period but also substantially increases the piston's lifespan by reducing friction and wear within the cylinder, making it a superior choice for your 125cc engine rebuild.
