Naraku Racing secondary gearbox NK900.98 +25% for 125/150cc 4-stroke scooters with GY6 152/157QMI engine

Have you already installed a tuning cylinder in your 4-stroke scooter, but are still not satisfied with the top speed?
Normally, the transmission ratio of the drivetrain is too short for the increased power despite de-throttling the variator and the top speed can otherwise only be increased by a higher engine speed, which is not the optimum solution.

We have the right product for this!

The Naraku secondary gearbox increases the transmission ratio by 25% for a higher top speed.
