Vertex pistons are manufactured using Low-Ex aluminium alloys with 12%, 18%, or 21% silicon content depending on the application. They are produced using gravity casting or hydraulic forging, followed by a heat treatment process. Machining is done with the latest CNC machines and diamond tools, achieving specific surface finishes. Each piston undergoes rigorous quality control. Vertex pistons feature a black Molybdenum Bisulphite coating for break-in and friction reduction, and a newer Phosphate Coating for increased hardness, porosity, and durability. This piston is 80mm with a 270cc displacement and a 13.5:1 compression ratio.

FULL DESCRIPTION

Vertex 270cc Big Bore Piston Kit 80mm

Upgrade the performance of your machine with this precision-engineered Vertex Big Bore piston kit. Designed to increase displacement to 270cc with an 80mm bore and 13.5:1 compression ratio, this piston is manufactured using exotic Low-Ex silicon-charged aluminium alloys. Through advanced gravity casting and hydraulic forging processes, Vertex ensures a refined material structure that delivers superior strength and reliability under demanding riding conditions.

Every piston undergoes a high-tech heat treatment process using automatic HT implants and hot water quenching to optimize the alloy properties. Machining is performed using state-of-the-art CNC technology and diamond tooling to ensure precise surface finishes tailored specifically for high-performance engine applications.

Key Features

  • Advanced Alloy Composition: Utilizes low-expansion silicon-charged alloys (12 percent to 21 percent) for consistent thermal stability.
  • Precision Machining: CNC machined with diamond tools for exact tolerances and superior surface finish.
  • Dual-Layer Coating: Features a Molybdenum Bisulphite black coating to reduce friction and assist with the initial break-in period.
  • Enhanced Durability: Incorporates an all-over Phosphate coating inspired by Formula One technology, providing increased hardness and improved adhesion for the Molybdenum layer.
  • Rigorous Quality Control: Each piston is subjected to thorough manual and automatic testing to meet the highest industry standards.
  • Compression Ratio: Engineered for a 13.5:1 compression ratio to maximize power output.

This big bore kit provides the perfect balance of increased displacement and long-term durability, making it an ideal choice for riders looking to enhance engine power while maintaining the quality and reliability expected from Vertex components.
