Features

  • Forged from high-silicon aluminum alloy for maximum strength and dependability
  • Wiseco offers a complete range of popular piston models and years for both trail and racing applications
  • Durability, longevity and increased horsepower
  • Innovative forging design and piston skirt provide maximum horsepower and torque
  • Features forged pistons, rings, wrist pins, and circlips
  • Now you can own the same race parts as all the top race teams
  • These high-tech piston designs offer maximum compression ratios, ultra-stiff strutted forgings, and titanium nitride-coated rings, which all add up to more power that is sustained longer
  • When blow-by starts to increase on other pistons and power starts to fade, Wiseco Race Series parts continue sealing and performing
  • Have additional features over standard Pro-Lite parts
  • Each piston is E-Coated on the crown, ring grooves, and pin bore, for maximum wear resistance and protection from micro-welding, galling, and detonation
  • GP Series parts generally have less machining on the outside, which helps seal up the bore for increased compression
  • Additionally, boost ports are removed for a more predictable powerband and increased pull on the top end
