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 Polini Primary Transmission 14/39 Piaggio Diesis / Zip SP LC after 2000. Best combined with a 50cc or 70cc sport cylinder, for increasing top speed while preserving excellent acceleration.
