Vertex pistons are manufactured using Low-Ex aluminium alloys, silicon charged to specific percentages based on application. The manufacturing process involves gravity casting or hydraulic forging, followed by a heat treatment process in an automatic implant with solubilization by quench in hot water. Machining is performed using CNC machines and diamond tools to achieve specific surface finishes. Each 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 is also available, offering increased hardness, surface porosity, and superior adhesion and durability for the Molybdenum Coating. This piston has a bore of 77.96mm and a compression ratio of 15.05:1.

FULL DESCRIPTION
Vertex G.P. Racers Choice High-Compression Piston
The Vertex G.P. Racers Choice piston is engineered for performance-focused riders who demand reliability and power from their engine. Designed with a high compression ratio of 15.05:1 and a precise 77.96mm diameter, this Grade B piston provides an essential upgrade for maintaining optimal engine efficiency and combustion chamber pressure.
Vertex utilizes advanced manufacturing techniques to ensure each piston meets rigorous performance standards. By employing exotic Low-Ex (low expansion) silicon-charged aluminium alloys, these pistons maintain structural integrity under extreme thermal stress. The material undergoes a refined heat treatment process using automatic solubilization and water quenching, ensuring consistent durability across the entire component.
