Checking engine oil level (fig. 71)
Engine oil level can be checked through the sight glass (1)
on the clutch cover on the right side of the engine.
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 next to 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).
