Ducati Diavel Service Manual: Headlight aim

The motorcycle must be perfectly upright with the tires inflated to the correct pressure and with a rider seated, perfectly perpendicular to the longitudinal axis.

Position the motorcycle 10 metres from a wall or a screen.

On the wall or surface, draw a horizontal line at the same height from the ground as the centre of the headlight and a vertical line aligned with the longitudinal axis of the motorcycle.

Note

If possible, perform this check in conditions of low ambient light.

Switch on the low beam. 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 headlight from the ground.

Note

This is the procedure specified by italian regulations for checking the maximum height of the light beam.

The vertical alignment of the headlamp can be adjusted manually by turning screw (1).

Turn the screw (2) to set beam height.
