As far as i know, yz 125's are built primarily for riders 140-180 pounds, so you could say the normal wieght is 160 pounds. However, heavier or lightersprings can be used to drastically increase this range. With aftermarket springsthe acceptablewieght could be 120-200 pounds. To little or too much wieght will be a dis-advantage on the track.
