That and simply having a 6 speed does not automatically make it better than having a 5 speed. There are a LOT of people, good example is the AutoX world who would rather have the 5 speed for the wider gear ratios. Many times the 6 speed and 5 speed final drive is the same between models, the 6 speed simply has an extra gear somewhere between 1 and 2 or 2 and 3 or whatever.
