Well I for one think this will hurt the dedicated riders more than the impact they are trying to have on the screwed up parents...
My youngest started on a PW50cc bike because of skill level and physical size at 5yrs old. His next bike was a PW80 because he out grew the 50cc. Long story short.... he now rides a KX65, this is a race ready motocross bike..... it took allmost 5 yrs of riding to get to this skill level. Down in CC up in class....
This sceniaro is something lawmakers can never account for....
