Notes and Safety Scooter gearboxThe 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!
