At least the 250 only has one. (And no fuel filter as standard, you be surprised at the tiny size a bit of grit needs to be to jam the float) Not a good example, btw. Bikes tend to be conservative in their design. Anything 'odd' rarely lasts a model or two. Hey, it works, people buy them, why change? (I think I just described Harley Davidsons business plan.)
