Do motocross racers have assigned numbers?

Answer 1

yes they do.

These are the American Motorcyclist Association (AMA) 2012 national numbers for pro-licensed riders competing in Monster Energy AMA Supercross, an FIM World Championship, and the Lucas Oil AMA Pro MX Championship for the 2012 season.

All riders must use the assigned national 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, the rider must use the assigned national number.
