Ducati Diavel Service Manual: Adjusting the rear shock absorber
The adjuster (1) located on the lower connection holding the shock absorber to the swingarm adjusts the damping during the rebound phase (return).
The knob (2), located on the left side of the motorcycle, adjusts the preload of the shock absorber external spring.
Turn the adjuster (1) clockwise to increase damping h; or counter clockwise to reduce damping s.
Standard setting from the fully closed position (clockwise): -unscrew adjuster (1) by 8 clicks.
Spring preload: 15 mm.
The two nuts (2) on the upper part of the shock absorber serve to adjust the preload on the external spring. To change spring preload, slacken the upper locking ring nut. Then tighten or slacken the lower ring nut to increase or decrease spring preload.
Important
The knob (3) located on the expansion reservoir of the shock absorber adjusts the damping during the compression phase.
Turning the adjusters (1) or the knobs (2) and (3) clockwise to increase preload damping; they decrease turning them in the opposite direction.
Standard setting: from fully closed (clockwise) loosen: register (1) of 12 clicks; knob (2) fully open (counter clockwise); register (3) of 25 clicks.
Spring preload: 18 mm (max.18 Mm - min.25 Mm
Warning
The shock absorber is filled with high-pressure gas and can cause injuries if inexpertly dismantled.
Important
If the motorcycle is to be ridden with a pillion rider and luggage, we
recommend setting the rear shock absorber spring
preload to the maximum to ensure the best handling and proper ground clearance
at all times. It may also be necessary
to adjust the rebound damping accordingly.
Adjusting the front fork
The front fork used on this motorcycle has rebound, compression and spring
preload adjustment.
This adjustment is done using the outer adjusters:
Rebound damping;
Inner spring preload;

Refitting the cylinder/piston assembly
If new units are used, it is necessary to couple the cylinders and pistons of
the same selection (see paragraph "overhaul Of the cylinder
barrel/piston components" of this section).
If the pistons have been separated from their cylinders, before reassembling
these components, position the p ...
Key-on/key-off using the red key on the handlebar with the active key
A key-on can be performed by pressing the red key (6) on
the handlebar in the hands free on/off position and in
the presence of the active key (3, fig. 77).
Note
The active key (3, fig. 77) Has a range of approx. 1.5 M,
therefore it must be located within this range.
Key-off can be performed ...
Absolute pressure sensors
Introduction
The engine control system of the diavel is equipped with two absolute
pressure sensors, with one connected to the intake
duct of each cylinder (map 1 cylinder 1 - horizontal - map 2 cylinder 2 -
vertical). They are used by the control unit to
determine the quantity of fuel to be ...
