Description
Higher or lower gear ratio might be the deciding factor in how your scooter will perform. A higher ratio (shorter transmission) will make the engine reach maximum horsepower more quickly, meaning acceleration will be improved, sacrificing a bit of top speed. A lower gear ratio (longer transmission) has the opposite effect - higher top speed and slower acceleration.
This is the Malossi Secondary Transmission 15/47 (gear ratio = 3.13) Vespa ET4 / LX / S 2V / LX / S 4V 50cc with straight teeth for reducing friction and heat.
15/47 -> gear ratio: 3.13 = +17% for 2V / +25% for 4V
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!
