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.
