Vertex Cast Big Bore Piston Kit for 250cc 2-Stroke

Upgrade your motorcycle's performance with the Vertex Cast Big Bore Piston Kit, specifically engineered for 250cc 2-stroke engines. This kit delivers enhanced power and durability, making it an ideal choice for riders seeking a significant boost in their engine's capabilities.

Description

The Vertex Cast Big Bore Piston Kit is designed to elevate your 250cc 2-stroke engine's performance by increasing displacement, torque, and peak horsepower. Crafted from a high-quality gravity-cast aluminum alloy with an 18% silicone content, this piston offers an exceptional balance of lightness and strength. Every Vertex motorcycle piston undergoes a rigorous T-5 hardening and tempering heat treatment cycle, ensuring superior durability and resistance to wear under demanding conditions. The piston skirt features an advanced Molybdenum Disulphite coating, which significantly reduces friction for a faster, more efficient break-in period and contributes to an extended piston lifespan. Designed in original OE form for big bore cylinders, this kit ensures precise fitment for a 68.00 mm bore size, with a piston diameter of 67.95 mm. It maintains a standard compression ratio, providing reliable performance while maximizing your engine's potential.
