Another thing I've noticed is that a lot of racing cars and motorcycles have gear ratios that are very closely spaced. For example, a lot of those Japanese road bikes may have a 5 speed transmission with a overall ratio span less than 3 or 2.5. (if you divide the tallest gear by the shortest, they are usually less than 3). Why is this?
Does anyone know the gear span (and ratios if possible) of a typical F1 car or Rally car?
