Supplier's note

  1. Technical Breakthroughs:

    • Forged Aluminum/Steel Alloy: Reduces weight by 20% compared to cast pistons while maintaining structural integrity.
    • Triple-Layer Ring Coating: Achieves 40% lower friction than standard cast iron rings, enhancing power delivery.
    • DLC-Coated Pin Bores: Extend lifespan by 50% in high-temperature environments.

  2. Optimal Version Selection:

    • Base Model: Ideal for street-legal bikes requiring reliable performance without extreme modifications.
    • Advanced Model: Targets high-revving engines (e.g., racing bikes) needing improved thermal and wear resistance.
    • Pro Model: Designed for professional racers, with a 15:1 compression ratio enabling 25% higher horsepower output than stock pistons. With its 350°C thermal tolerance, it safely handles sustained high-RPM operation. Pair it with forged connecting rods for peak efficiency.
