secondary transmission gear up kit -NARAKU- racing 18/36 +35% for GY6 125/150cc 152/157QMI

Who does not know it? Performance tuning with big bore cylinders, the scooter accelerates significantly, but it does not get much faster. As a rule, the end is at 90-100 km / h. Variomatik still brings something, but the final speed is not enough. The reason for this is the too small transmission ratio of the original gearbox. So that the relatively weak original engine can achieve the required power, it is translated too short. NARAKU offers a 35% longer gearbox, which achieves the optimal gear ratio extension in coordination with the power development of 4-stroke engines. Prerequisite is at least a 160cc cylinder kit.
With the NARAKU gearbox, the scooter now achieves a significantly increased top speed without sacrificing acceleration.
Simply replace and you're done. No special tools required. A new gearbox cover gasket should be ordered separately.

Fits all 125 and 150cc GY6 engines._{AI-translation}
