Bore: 51.96mm
Compression: Standard Compression
Sizing: Standard Bore

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.
