Gas Gas MC 85 2021-2023 Grade D 46.97mm Flat Top Piston
Vertex pistons are manufactured using Low-Ex aluminium alloys with 12%, 18% or 21% Silicon content depending on the application. Pistons are made using gravity cast or hydraulic forging processes, with material structure refined by advanced heat treatment. Machining is performed using the latest CNC machines and diamond tools to achieve specific surface finishes. Each Vertex piston undergoes rigorous manual and automatic quality control. Pistons are coated with a special Molybdenum Bisulphite black coating for break-in and friction reduction. A new, all over Phosphate Coating has also been introduced, offering increased hardness and superior adhesion qualities for extended coating durability. This specific piston is Grade D, 46.97mm, flat top.

FULL DESCRIPTION
High-Performance Vertex Flat Top Piston
Upgrade your engine performance with this precision-engineered Vertex flat top piston. Designed for riders who demand reliability and power, Vertex pistons are crafted using advanced low-expansion silicon-charged aluminum alloys to ensure optimal thermal stability and long-lasting durability.
Advanced Manufacturing Technology
Each piston is produced through a sophisticated gravity cast or hydraulic forging process. The material structure is further refined through cutting-edge heat treatment technology, involving automated solubilization and hot water quenching. The final machining is performed on state-of-the-art CNC equipment using diamond tools, ensuring exact tolerances and a surface finish tailored to high-performance engine requirements.
Superior Coating and Friction Reduction
Vertex pistons feature a dual-layer coating system designed to maximize engine longevity and efficiency:
- Molybdenum Bisulphite Coating: A specialized black coating that aids in the break-in process while significantly reducing friction during operation.
- Phosphate Coating: Borrowing from Formula One engine development, this all-over base coating provides a slight increase in surface hardness. Its light porosity ensures superior adhesion of the Molybdenum layer, effectively doubling the durability of the piston coating.
