The gearbox - tuning via gear ratio

The gearbox or transmission is a mechanical device that transmits a motion from one part to another, with the possibility of changing speed and torque by gearing up or gearing down. In a scooter, there is the primary transmission (input shaft to torque drive + intermediate shaft) and secondary transmission (intermediate shaft + output shaft to wheel). The gear ratio has a great impact on acceleration and top speed. A short gear ratio gives good acceleration, but is a little weak on speed, which can be compensated by a longer gear ratio.

Since the gearbox is a very complex subject, here we have a gearbox tutorial for you that will help you choose your new gear ratio.

The complex world of gear ratios

Do you simply want to replace gearbox components because they are defective or worn? Or do you want to adjust the gear ratio after upgrading to a more powerful cylinder? In both cases, we recommend replacing both primary and secondary gears at the same time.

For very powerful engines, we recommend selecting the gears in a way that the final drive ratio can adequately convert the power delivered by the engine. Using a longer gear ratio may actually worsen acceleration, so you should always match the gearbox to the available RPM. Longer does not always mean better, it is best to get enough information before installing new gears!

In our online store we carry a wide range of individual gears and complete gearboxess for most scooters, mopeds and maxi scooters. Leading brands such as
