The transmission ratio of the gearbox has a major impact on engine performance. The gear ratio is changed it can keep up with the surplus power of a tuned engine and transmit this power into tangible results, be it in terms of top speed or acceleration. A taller gear favors top speed at the expense of acceleration.
This is a primary transmission Polini, teeth = 18 / 69.
Note: Changing the gear on the intermediate shaft requires a hydraulic press or a corresponding assembly tool.
Scooter gearbox
The transmission of scooters and some mopeds is located in a case behind the clutch and torque driver and has the function of reducing rpm and ultimately driving the wheel axle.
The transmission of a scooter has a direct influence on top speed. If the engine develops enough power and torque at low rpm, you can choose a longer gear ratio to achieve a higher top speed without any noticeable loss in acceleration.
Please note: if you don't have a press, better choose pre-assembled gears!
