I'm in the market for a 450.06 to 08 model and I'm wondering which brand from the factory is better for shorter riders? I don't want to shave the seat and I don't want to mess with suspension. I'm 5'10 and I know that's not short but i prefer shorter sitting bikes. Is there enough difference between brands to even matter? Any answers are appreciated. Also this question is for a friend of mine looking at getting a 450 and he is fairly short.
