Naraku Racing V2 90cc Cylinder Kit GY6 / Kymco 4-Stroke 52.4mm incl. Head

The Naraku Performance POWER-RACING V2 90cc cylinder kit is one of the most powerful upgrades available for GY6 and Kymco 4-stroke scooters. Displacement is increased from 50cc to a massive 90cc, delivering significantly more torque and power.

The main advantage over standard GY6 cylinders is the optimized cylinder head with larger valves, ensuring maximum intake and exhaust flow and improved cylinder filling.

The supplied low-friction coated piston features two additional CNC-machined oil grooves that retain oil for improved lubrication and better protection during break-in.

The kit is designed for easy installation and fits directly onto the original crankshaft. For best performance, a 24mm carburetor is recommended.
