This high-strength material is specifically designed to withstand the intense pressures and rigorous conditions found in modern high-performance four-stroke engines.

Precision is at the core of the Vertex design. This Grade C piston features a 78.98mm diameter and a 14.4:1 compression ratio, providing an optimized combustion environment to maximize output and efficiency.

Key Features

  • Forged 2618 Aluminum Alloy: Offers superior strength and durability under extreme operating temperatures and high engine loads.
  • MOS2 Skirt Coating: Each piston is finished with a Molybdenum Disulphide (MOS2) coating. This advanced treatment aids the break-in process and significantly reduces friction and wear on the piston skirt.
  • Precision Sizing: Vertex pistons are engineered with specific profiles to ensure an exacting fit within the cylinder, resulting in enhanced engine performance and improved seal.
  • High Compression Ratio: Designed at 14.4:1 to provide an immediate boost to engine performance and throttle response.
  • Grade C Specification: Meticulously measured at 78.98mm to allow for the perfect cylinder-to-piston clearance required for peak performance.
