We are a family of 6, our youngest is 4 he has been riding with a restrictor on the 50 since he was 2 years old riding in the forest his whole life. Now there are no classes offered to him until he is 6?!?!? What now do we risk the fine?!?!? also my 15 year old son is 6ft.170lbs. our LT80 wont even go with him on it, what if the instructor refuses him, will they let him ride a larger atv to take the safety course. thanks!
