Product Info:

  • Exact fit A, B, or C pistons match your cylinder bore perfectly to maximize power and performance while reducing blow-by and oil consumption.
  • 2-stroke pistons have an 18% silicon content which decreases wear and thermal expansion, allowing for tighter running tolerances for more power, less noise, and longer lifespan.
  • High-tech Molybdenum Disulphide (MOS2) skirt coating for reduced wear and improved break-in.
  • 4-stroke pistons are forged from either 2618 or 3032 alloys for superior strength and durability.
  • All piston kits include piston, rings, wrist pin, and circlips.
  • Cast and Forged Replica pistons are OE replacements with stock OE compression ratios.
  • Cast and Forged Race pistons are unique with only one compression ring.
  • Forged Hi-Comp pistons increase compression and power over Replica pistons.
  • Forged GP Racer's Choice pistons have T-box forgings, unique dome profiles, surface treatments, and increased compression ratios to produce more power, strength, and durability.
  • Big Bore pistons increase displacement and power while maintaining stock compression ratios.
