TM MX / EN 250 1995 - 1999 GRADE B 66.34mm TWIN RING PISTON
Vertex pistons are manufactured using Low-Ex aluminium alloys, silicon charged with 12%, 18%, or 21% depending on the application. Pistons are produced using gravity casting or hydraulic forging, with material structure refined through a heat treatment process using automatic HT implants and hot water quenching. Machining is performed using CNC machines and diamond tools, achieving specific surface finishes. Each Vertex piston undergoes rigorous manual and automatic quality control. Vertex pistons are coated with a special Molybdenum Bisulphite black coating for break-in and friction reduction. A new Phosphate Coating, developed from Formula One engine advancements, offers increased hardness, light surface porosity, and superior adhesion qualities for extended coating durability. This piston is 66.34mm with twin rings.
