Minimum tread depth
Measure tread depth (S, fig. 40) at the point where tread
is most worn down. It should not be less than 2 mm and
anyway not below the legal limit.
Important
Visually inspect the tyres at regular intervals for
detecting cracks or cuts, on the side walls especially,
bulges or large spots that are indicative of internal
damage. Replace them if badly damaged.
Remove any stones or other foreign bodies caught in the
tread.

Checking engine oil level (fig. 41)
Engine oil level can be checked through the sight glass
(1) provided on the clutch cover.
When checking oil level, the motorcycle should be
upright and the engine cold. Allow a few minutes for oil
to settle to a steady level after stopping the engine. Oil
level should be between the marks near the sight glass.
Top up oil level with SHELL Advance Ultra 4, if low.
Undo the filler plug (2) and top up to correct level. Refit
the plug.
Important
Engine oil and oil filters must be changed by a
Ducati dealer or authorized workshop at regular intervals,
as specified in the routine maintenance chart (see
Warranty Card).
