Walt, the 250f may be a little stronger down low than my cr, I dont think it has the mid range that my cr does but it revs to the moon, the biggest differnce is that the track was really hard pack, and the lil thumper would hook up and accelerate out of the turns with no drama. I weigh 215, (yeah I know) and the bike would let me clear anything i clear on my CR, and it felt more stable on the jump faces, I think I might have to pop for new fork springs, since the bike wasn't mine I didn't mess with the clickers all that much, but the shock will be OK. I had an absolute blast on it! The guy I was riding with stepped off of a crf450 for it and swears he's faster on this one, I do know he can do more laps without pulling over, I dont know if he's much faster on this one a(fter the first two laps he gaps me anyway), but he is definitely not slower. :aj:
