2012 FIM Technical Rules Motocross

The color scheme for the background of the side number plates and the numbers
is free. However, there must be a clear color distinction between the color of the
number and the color of the background. The FIM logo must be in black or white.

The figures must be clearly legible and like the background must be painted in
matt colours to avoid reflection from sunlight. In general, the following minimum
dimensions must be respected on front number plates:
Height of figure: 140 mm
Width of figure: 70 mm
Width of stroke: 25 mm
Space between 2 figures: 15 mm
However, the following minimum dimensions must be respected on the side
number plates:
55.08
Height of figure: 100 mm
Width of figure: 70 mm
Width of stroke: 25 mm
Space between 2 figures: 15 mm
The English form for numbers must be used. That is single vertical line for the “one”
and a simple sloping line without a horizontal line for the “seven” (see diagram O).
55.09
All other number plates or markings on a motorcycle liable to cause confusion with
the number must be removed before the start of a competition.
Whenever official time keeping methods (transponders) are being used in the
FIM World Championships and Motocross of Nations events, competitors will be
allowed to put publicity on:
• the front number plate (for dimensions, see Art. 55.03). Publicity may be put
within a space, 50 mm from the top or bottom section of the number plate,
(See diagram O, the shaded area is reserved for publicity).
