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 17/49 (gear ratio = 2.88) Vespa GTS Super / GTS Super Sport 125cc with straight teeth for reducing friction and heat.
17/49 -> gear ratio: 2.88 = +10%
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!
