I am thinking about stepping down from my 03 crf450 to a crf250. I am a little over 6 ft tall and weigh 150 pounds. I love the power of my 450, but all that power along with the weight of the bike just wears me out to quick. I race at the amateur level and feel that I would be faster on a lighter bike. But I do wonder if I will be disappointed with losing the awesome power of the 450. I went from a 250 2stroke to a 125 2stroke many years ago and hated to 125 due to the pipey motor and lack of bottom end. I fear that I will have the same problem again going from the 450 to the 250 4stroke. If anyone has been in the same situation and stepped down, I would appreciate your thoughts, or anyones thoughts on my situation.
