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 durabiltiy.
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.
