I just got my ATVA news and it talks about rule changes for 2004 for teen quad races. In the 200cc 2 stroke and the 300cc 4-stroke, the age has been lowered to 13 instead of 14. As long as the rider fits the quad. Thats some good news for us, but I think thats going to only apply to mx. I wish there was a hare scramble class for my son. It seems like the lowest age I can find for a 300 is 16.
