Beam setting (fig. 74)
When checking the beam setting, set the motorcycle
upright. Tyres should be inflated to 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 away.
Draw a horizontal line at the height of the centre of the
headlamp and a vertical one at the longitudinal axis of the
motorcycle.
If possible, perform the operation in dim light.
Switch on the low beam.
the upper edge between the dark area and the lit area
should not be more than 9/10th of the height of the
headlamp centre from the ground.
Notes
This procedure is the one specified by Italian
regulations for checking the maximum height of light
beams.
Owners in other countries should adapt this procedure to
the regulations in force in the country where the
motorcycle is used.
The vertical setting of the headlamp can be adjusted by
turning the adjusting knobs (1, fig. 75) on the left side of
the headlamp. Rotate the knobs clockwise to lower the
beam or anticlockwise to raise it.
Notes
To access the lower knob, you must first remove the
headlamp fairing as described on page 57.
