i am working on gettting an 2003 rm250. i am coming off of a 2001 cr125. is there that much of a difference in power delivery? because the cr is terrible on the bottom end. the rm250 has an 8 oz flywheel though. i ride mostly trails though so am not on the pipe all the time but i do like to go to the track. does anyone have an rm250 that can chime in on what i should expect, power wise?
