YES! In recent years the rules have been changed to make it harder for the skaters to score a medal.
The racer must be a member of the AMA to be allowed to race. Then they must be at least twelve years old. The bike being entered in the motocross has to be AMA approved. Each rider must wear a full face helmet, shatter proof goggles, protective pants, jersey and motocross boots that are at least eight inches tall.
