TopEnd piston kit VERTEX VTK23630A-2 Cylinder 66,4mm Piston 66,34mm

PISTON KIT

• 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
• 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
