YAMAHA YZ 250 1999-2022 GRADE B 66.35mm SINGLE RING FORGED PRO RACE PISTON
Vertex pistons are manufactured using low-expansion silicon-charged aluminum alloys, either gravity cast or forged, and refined with advanced heat treatment. Machining is performed using state-of-the-art CNC machines and diamond tools to achieve specific surface finishes. Each piston undergoes rigorous quality control. Vertex pistons feature a Molybdenum Bisulphite black coating for break-in and friction reduction, with a newer Phosphate Coating for increased hardness, porosity, and extended durability. This piston has a bore of 66.35mm and a single ring.
