5.3 Number & Display Regulations

D. Colors - all Expert competitors will use black numbers on a white background.
Numbers must be approximately 8” high and 1” wide, of standard block lettering
with no shading or outlining. Novices will use black numbers as specified above,
but the numbers shall be on a yellow background. Expert class champions
from the previous MRA season are permitted to use white numbers on a black
background with the same size and style restrictions.
The height of the numbers should be changed from 8" to something smaller like 5" or 6". It doesn't seem possible on the newer bike to fit an 8" number and have them legible from the front and sides. Thanks!
