Who hasn't experienced it? Performance tuning with big bore cylinders has been carried out and the scooter accelerates significantly, but it doesn't get much faster. As a rule, it stops at around 90-100 km/h. Tasuching the variator still helps, but the top speed is still not enough. The reason for this is that the transmission ratio of the original gearbox is too low. The gear ratio is too short for the relatively weak original engine to achieve the required power. Naraku offers a 20% longer gearbox, which achieves the optimum gear ratio extension in coordination with the power development of 4-stroke engines.
With the Naraku NK901.23 gearbox, your scooter now achieves a higher top speed without sacrificing acceleration.
