If you plan to run with MS just follow the rule book. All Novice riders are required to have a black number on a yellow background. Number Plates must be clear and easily readable from 100 feet. All motorcycles must display three separate number plates; one on the front and one on each side, tail section preferred. Numbers must be as large as possible to fill required Number Plate areas. Numbers must be a minimum of 4" tall with a minimum 1/2" spacing between numbers and the background border. For Novices this does not mean outline, a continuous yellow background must encompass the entire number group with no voids so that there can be no confusion to be mistaken as an expert custom color. Side number plates not able to fit properly on the tail section must be visible when the rider is in riding position on lower fairings.
