Upgrade your scooter's performance to Power levels with the MAIC-R Racing Cylinder Kits,  Amasterpiece of engineering designed for those who demand the ultimate in power and precision. This kit, available for both 125cc and 200cc engines, represents the forefront of MAIC-R innovation in high-performance scooter upgrades.

Cylinder Innovations:

• Dragster 125 Upgrade: Achieves a displacement of 191.36cc over the standard 124cc with a bore of Ø 72 mm and stroke of 48 mm. 
• Dragster 200 Upgrade: Achieves a displacement of 236.15cc over the standard 180cc with a bore of Ø 72 mm and stroke of 58 mm. 
• 
  
• Advanced Material: The cylinder is crafted from a primary Iron alloy enriched with a high content of hardened and tempered steel, ensuring durability and resistance to wear. The liner features a silicon carbide coating in a galvanic nickel die, finished with crossed smoothing and two diamond passages for optimal surface integrity and minimal tolerances.
• Optimized Heat Dissipation: Both the cylinder and piston have recalculated and enhanced heat exchange surfaces, promoting efficient thermal management for sustained performance and a higher Compression.

Piston Perfection:

• Compact Design: The ultra-compact FORGET piston, equipped with three rings, is engineered for maximal efficiency and power output.
• Superior Material: Made from a special aluminium alloy with a high silicon content, it features low thermal expansion and a tin facing on the sliding surfaces to reduce friction and enhance durability.
• Lightweight & Strong: The piston is both lightened and reinforced, benefiting from numerical control machining for precision and upgraded surfaces for improved heat dissipation.

 MODIFICATIONS ON ENGINE BLOCK ? :  NO, you need to bore the original engine block to 74,5mm/75mm
