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.
