YAMAHA YFM RAPTOR / GRIZZLY 660 2001-2008 GRADE B 100.45mm STANDARD COMPRESSION 9.9:1

Vertex Standard Compression Four-Stroke Piston

Upgrade your engine performance with the Vertex four-stroke piston. Engineered for riders who demand reliability and power, this piston is forged from high-quality 2618 aluminum alloy. This advanced material composition is specifically designed to withstand the intense pressures and rigorous conditions associated with modern four-stroke engine operation.

Vertex pistons are renowned for their precision engineering and attention to detail. Every piston features a specialized Molybdenum Disulphide (MOS2) coating on the piston skirt. This coating serves a dual purpose: it facilitates a smoother break-in process and significantly reduces friction, which helps minimize wear and extend the lifespan of your engine components.
