Vertex Cast Replica Top End Piston Kit for 2-Stroke

Ensure peak performance and reliability for your 2-stroke engine with the Vertex Cast Replica Top End Piston Kit. This comprehensive kit provides a high-quality, OE-style replacement piston designed for durability and a precise fit, making it ideal for engine rebuilds or maintenance.

Description

Restore your motorcycle's power and efficiency with this premium Vertex 2-Stroke Top End Piston Kit. Engineered as a direct OE replacement, this cast replica piston kit is meticulously crafted from gravity-cast aluminum alloy, featuring an impressive 18% silicone content for superior strength and excellent thermal expansion characteristics. This robust composition ensures the piston maintains its integrity under the extreme heat and pressure of a high-performance 2-stroke engine, specifically designed for 250 cc displacement. The piston undergoes a specialized T-5 hardening and tempering cycle, enhancing its overall durability and resistance to wear.

A key feature is the advanced Molybdenum Disulphite coating applied to the piston skirt. This high-tech treatment significantly reduces friction during operation, promoting a faster break-in period and substantially increasing both piston and cylinder life. With a standard compression ratio and a precise 66.40 mm cylinder diameter, this kit guarantees optimal engine performance. The complete top end rebuild kit includes everything you need for a seamless installation: the piston, rings, pins, circlips, a full set of top end gaskets, and a wrist pin bearing, providing a hassle-free solution for your 250cc engine refresh.
