Vertex Cast Flat Top Piston Kit for 85cc 2-Stroke

The Vertex 85cc 2-Stroke Piston Kit is engineered for peak performance and durability in your motorcycle engine. Featuring a robust gravity-cast aluminum alloy construction with a flat top design, this piston kit delivers exceptional strength and a lightweight profile crucial for high-revving 2-stroke applications.

Description

This high-quality Vertex cast piston is meticulously crafted to meet the rigorous demands of motocross and off-road riding. Each piston undergoes a precise T-5 hardening and tempering cycle, enhancing its structural integrity and resistance to wear under extreme conditions. The skirt of every piston is treated with an advanced Molybdenum Disulphite coating, significantly reducing friction during operation. This specialized coating ensures a faster break-in period and extends the overall lifespan of the piston, providing consistent performance over time. Designed specifically for 85cc 2-stroke engines with a 47.00 mm bore, this kit offers a precise fit and reliable operation. Made from a gravity-cast aluminum alloy containing 18% silicone, the piston achieves an optimal balance of lightness and strength, ensuring responsive power delivery and sustained engine health. The included OEM replacement rings further guarantee compatibility and performance, making this 47mm bore piston an ideal choice for rebuilding or upgrading your engine.
