Bought a brand new 2017 CRF 250r , had it one year the crank case broke , my son kicked it over and the crank case broke .. he only weighs 140lbs ..we have had many different dirtbikes the last 25 years and have never had this problem ..thinking it is a manufacturer defect ..we have talked to many people ..nobody has seen anything like this .. Honda will not do anything about it or even look at the pictures .
