I'm looking at going up from a crf230 to a crf450x. Is that a bad idea? I know it has way more horsepower but I figured i could stick to low gears if I need to. But I've outgrown my other 2 bike very quickly. (xr100 and crf230.) So I was thinking that I would get used to the 450x quick enough. Any thoughts or personal experience? I'm 6ft and 135lbs. I'd say i'm an intermediate skill level.
