I know I asked about different dirt bikes before...but now that I went to the bike show and looked at some of the bikes...I was thinking of the CRF450R as a first dirt bike for me. I am nuts? Is that too much bike for me? I am a big guy, so I would need some power to get around, plus I don't want to out grow it too fast. My wife sat on the CRF125 and likes that one for her. I mean, besides the CRF450, what else can I choose from?
