- 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
