The American Motorcyclist Association is pleased to announce professional numbers for pro-licensed riders competing in Monster Energy AMA Supercross, an FIM World Championship, and the Lucas Oil AMA Pro Motocross Championship for the 2013 season.
All riders must use the assigned professional number for competition as listed. In addition, the current champion must run the No. 1 plate when competing in the class or region in which the No. 1 plate was earned. When competing in a class outside of the class where the championship was earned, a rider who holds a No. 1 plate in another class must use the assigned professional number.
