Ducati Diavel Service Manual: 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:

1. Rebound damping;
2. Inner spring preload;
3. Compression damping.

Park the motorcycle in a stable position on its side stand.

Turn the adjuster (1) on fork leg top with a flat screwdriver to adjust rebound damping.

On the carbon model, adjustment is done using the knob (b) on the fork leg, without a screwdriver.

Turn the adjuster (3) on fork leg bottom with a flat screwdriver to adjust compression damping.

As you turn the adjusters (1) and (3), you will hear them click. Each click corresponds to different damping setting.

The stiffest damping setting is obtained with the adjuster turned fully clockwise to the "0" position. Starting from this position, turning counter clockwise, you can count the turns.

To change preload of the spring inside each fork leg, turn the hex. Adjuster (2) with a 22 mm hexagon wrench, starting from the fully open position (clockwise). From reference (a), every full turn clockwise corresponds to 1 mm of preload of the spring, up to a maximum of 15 mm, corresponding to 3 full turns.

Standard settings, from fully open position, are as follows: compression: 1 turn and a half; rebound: 1 and a half turns.

Spring preload: fully open (counter clockwise).

Important

Adjust both fork legs to same settings.
