FULL DESCRIPTION

Vertex High-Performance Four-Stroke Piston

Upgrade your engine's performance with the Vertex four-stroke piston. Engineered for riders who demand reliability and power, this piston is forged from premium 2618 aluminum alloy. This high-strength material is specifically chosen to withstand the intense pressures and demanding conditions found in modern high-revving four-stroke engines.

To ensure optimal longevity and a smooth break-in period, every Vertex piston features a specialized Molybdenum Disulphide (MOS2) coating on the skirt. This advanced coating significantly reduces friction and wear, protecting your engine components during operation.

Key Features

  • Precision Engineering: Manufactured from high-quality 2618 aluminum alloy for superior durability.
  • Advanced Coating: Molybdenum Disulphide (MOS2) skirt coating minimizes friction and aids in engine break-in.
  • Optimized Performance: Designed to provide a standard compression ratio of 13.5:1 for consistent power delivery.
  • Exact Sizing: Grade B piston measuring 76.95mm, engineered to maintain perfect tolerances within the cylinder.
  • Efficiency: Helps reduce blow-by and oil consumption, ensuring your engine runs cleaner and more efficiently.

Vertex pistons are designed to maintain internal tolerances, allowing for a perfect fit that maximizes compression and overall performance. Whether you are replacing worn components or performing a top-end rebuild, choosing a Vertex forged piston ensures your machine operates at its peak potential.
