Whether you are rebuilding your engine after countless hours on the track or proactively upgrading for a competitive edge, this kit provides the core component for a powerful and responsive motor.Developed with Vertex´s world-renowned expertise, this Pro-Race piston is the culmination of advanced technology and a race-derived profile. The specific shape is meticulously designed to optimize combustion efficiency, leading to improved throttle response and a noticeable increase in power across the entire RPM range. At its core, the piston is forged from a high-strength 2618 aluminum alloy, a material trusted in professional motorsports for its exceptional strength and resistance to the extreme pressures and temperatures of a high-performance two-stroke engine. This forging process ensures superior durability compared to cast alternatives, giving you the confidence to push your machine to its limits.To guarantee longevity and consistent performance, every Vertex piston undergoes a crucial T-5 hardening and tempering cycle. This advanced heat treatment process strengthens the aluminum´s internal structure, enhancing its resistance to wear and thermal stress for a significantly longer service life. Furthermore, performance is enhanced right from the first start-up. The piston skirt features a high-tech Molybdenum Disulphite coating, an advanced solution that dramatically reduces friction during the critical engine break-in period. This not only allows for a faster, more effective seating of the components but also contributes to increased piston life by minimizing wear over the long term. This comprehensive approach to design and manufacturing makes it the ideal piston for a complete and professional top-end rebuild.Compatible models:YAMAHA YZ 250 1999-2021.Technical Specifications:* Product: Vertex Piston Kit* Category: Engine* Subcategory: Top End* Type: Pro-Race, Forged Race Piston* Reference: 22645B* Diameter: Ø 66.40 mm (Size B)* Attributes: Piston, Sets* Material: 2618 Forged Aluminum* Coating: High-Tech Molybdenum Disulphite on Skirt* Treatment: T-5 Hardening and Tempering Cycle. tradeinn Motardinn
