Vertex Cast Replica Piston Kit - 72mm Bore - 300cc - Size B - 24391B

The Vertex Cast Replica 2-Stroke Piston Kit delivers OE-grade performance and exceptional durability for your 300cc engine. Engineered with advanced materials and coatings, this piston kit ensures a reliable and powerful rebuild, precisely matching original equipment specifications.

Description

Experience robust and consistent power with this high-quality Vertex Cast Replica piston kit, specifically designed for 2-stroke 300cc engines. Each piston is gravity-cast from a premium aluminum alloy, boasting an 18% silicone content. This unique composition results in an extremely light yet remarkably strong piston, capable of withstanding the rigorous demands of high-performance motorcycles. To further enhance its resilience, every piston undergoes a meticulous T-5 hardening and tempering heat treatment cycle, significantly boosting its structural integrity and longevity.

For superior break-in and extended operational life, the piston skirts are expertly coated with a high-tech Molybdenum Disulphite (Moly) layer. This advanced coating minimizes friction, reduces wear, and promotes faster, smoother break-in periods. With a precise bore size of 72.00 mm and a piston diameter of 71.96 mm, this standard size B kit provides an exact OEM replacement fit. The included nitride coated steel rings ensure optimal sealing and compression, restoring your engine's peak performance.
