Headlight Aim - Ducati MONSTER S4R S Use And Maintenance Manual

Headlight aim

(fig. 61)
To check the headlight aim, place the motorcycle upright
with the tyres inflated to the correct pressure and one
person sitting astride the motorcycle. The motorcycle
should be perfectly vertical, with its longitudinal axis at
right angles to a wall or screen at a distance of 10 metres.
Draw a horizontal line on the wall at the height of the
centre of the headlight and a vertical one in line with the
longitudinal axis of the motorcycle.
If possible, perform this check in conditions of low ambient
light.
Switch on the low beam headlight.
The height of the upper limit between the dark area and the
lit area must not be more than nine tenths of the height of
the centre of the headlamp from the ground.
Notes
Note: 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 aim of the headlamp is adjusted by turning the
screws (1, fig. 62) that attach it to the side mountings.
