Vertex pistons are manufactured using Low-Ex silicon aluminium alloys (12%, 18%, or 21% silicon depending on application) via gravity cast or hydraulic forging processes. These blanks undergo a hi-tech heat treatment for material structure refinement, followed by CNC machining using diamond tools to achieve specific surface finishes. Each piston is subjected to rigorous manual and automatic quality control. Vertex pistons feature a special Molybdenum Bisulphite black coating for break-in and friction reduction, with an optional new Phosphate Coating for enhanced durability and adhesion. This is a Grade B 57.95mm twin ring replica piston.

FULL DESCRIPTION

Vertex Replica Twin Ring Piston - 57.95mm Grade B

The Vertex Replica Twin Ring Piston is engineered to deliver high-performance reliability and precise power delivery. Manufactured using exotic Low-Ex silicon-charged aluminium alloys, this piston is designed to withstand the high-stress environments found in modern two-stroke engines. Whether you are performing a routine top-end rebuild or looking for a performance upgrade, this component provides an ideal solution for maintaining engine longevity and efficiency.

Advanced Manufacturing and Durability

Vertex utilizes a sophisticated heat treatment process in a fully automated environment to refine the material structure of each piston. This cutting-edge method ensures optimal tensile strength and thermal stability. The machining process incorporates state-of-the-art CNC technology and diamond tooling to achieve exact tolerances and specific surface finishes tailored to your engine requirements.

Surface Coatings for Enhanced Performance

To reduce internal friction and ensure a smoother break-in period, this piston features a specialized Molybdenum Bisulphite black coating. Complementing this is an advanced Phosphate coating, a technology derived from Formula One engine development. This phosphate layer increases surface hardness and provides superior adhesion for the Molybdenum coating, resulting in significantly extended durability compared to standard aftermarket pistons.

Key Features

  • Precision Engineering: Manufactured using Low-Ex silicon-charged alloys for minimal thermal expansion and maximum durability.
  • Twin Ring Design: Optimized for consistent compression and effective heat transfer.
  • Molybdenum Bisulphite Coating: Reduces friction during the break-in phase and throughout the piston life cycle.
  • Phosphate Surface Treatment: Increases wear resistance and improves coating adhesion for long-term engine protection.
  • Quality Assurance: Every piston undergoes rigorous manual and automatic quality control inspections to meet strict engineering standards.
  • Grade B Sizing: Features a 57.95mm diameter to ensure a perfect fit within the cylinder.
