Piston Kit, Piston weight: 334g Piston Pin weight: 97g

  • Lightweight A2618 aluminum alloy billet piston with high temperature strength
  • Bridge design improves structural rigidity.
  • Profile optimization has shortened the Piston skirt height and reduced weight.
  • Short piston pit with lightweight boss part.
  • 2 layers of molybdenum coating to eliminate friction and improve initial functionality of the whole system.

Crankshaft Stroke 77.7 mm

  • Billet full counter crankshaft
  • Counterweights are efficiently located to decrease overall weight and improve overall balance.
  • Response is improved by reducing the weight of the pin journal and the center section by cutting the core of the pin journal to reduce the weight.

Connecting rods

  • Nickel Chrome Steel Billet H-Beam Connecting rods.
  • WPC treatment to improve strength
