    Depends....is it a CVT type "automatic"? Or being a pocket bike, it could just be a centrifugal clutch.

    Well, don't expect much longivity with that tranny. With careful lubing and maintenance, they usualy crap out at about 200-300 miles.

    No. Speed is effected most by the total drive ratio and the engine's power.
