Vertex pistons are manufactured using Low-Ex aluminum alloys with 12%, 18%, or 21% silicon depending on the application. They are produced using gravity casting or hydraulic forging, followed by a heat treatment process with solubilization by quench in hot water. Machining is done using CNC machines and diamond tools to achieve specific surface finishes. Each piston undergoes manual and automatic quality control. Vertex pistons feature a Molybdenum Bisulphite black coating for break-in and friction reduction, and a Phosphate Coating for improved durability and adhesion. This piston is grade C and has a 71.96mm diameter with a single ring.

FULL DESCRIPTION

High-Performance Vertex Single Ring Piston

Upgrade your engine performance with this precision-engineered Vertex single ring piston. Designed for riders who demand reliability and power, Vertex pistons are crafted using advanced gravity casting or hydraulic forging processes to ensure superior structural integrity and longevity.

Vertex utilizes exotic Low-Ex silicon-charged aluminium alloys, with silicon content ranging from 12% to 21% depending on the specific application. This material is further refined through a state-of-the-art heat treatment process involving automatic solubilization and hot water quenching, resulting in a piston that can withstand the intense internal pressures of high-performance engines.

Key Features

  • Advanced Manufacturing: Produced using the latest CNC machining and diamond tooling technology for exact tolerances and superior surface finishes.
  • Dual-Layer Coating: Features a Molybdenum Bisulphite black coating to reduce friction during engine operation and assist with a smooth break-in period.
  • Enhanced Durability: Incorporates a specialized Phosphate coating developed from Formula One engine technology. This creates a harder surface with microscopic porosity, significantly improving Molybdenum adhesion and doubling the coating's lifespan.
  • Strict Quality Control: Every piston undergoes rigorous manual and automated testing to ensure it meets the highest industry quality standards.
  • Specifications: Grade C, 71.96mm diameter single ring configuration.

Whether you are rebuilding for maintenance or looking to restore peak performance, this Vertex piston provides the professional-grade consistency needed for your machine.
