Beam setting
(fig. 51)
When checking beam setting, put the motorcycle upright.
Tyres should be inflated at the correct pressure and one
person should be sitting astride the motorcycle, keeping it at
right angles to its longitudinal axis. Place the motorcycle
opposite a wall or a screen, 10 meters apart from it, then
draw a horizontal line dictated by headlamp centre and a
vertical one in line with the longitudinal axis of motorcycle.
If possible, perform this check in dim light.
Switch on the low beam.
The height of the light spot (measured at the upper limit
between dark and lighted-up area) should not exceed 9/10th
of the height from ground of headlamp centre.
Note
The procedure described here is in compliance with
the Italian Standard establishing the maximum height of the
light beam.
Owners in other countries will adapt said procedure to the
provisions in force in their countries.
Beam vertical setting is carried out by turning the screws (1,
fig. 52) that secure it to the side supports.
