Clutch system
If there is too much play at the clutch lever and the
motorcycle jumps or stops when a gear is engaged,
this indicates air in the system. Contact a Ducati Dealer
or Authorized Service Centre to have the system
inspected and the air bled from the system.
Warning
The clutch fluid level in the reservoir tends to rise
as the friction material on the clutch plates wears out.
Do not exceed the specified level (3 mm above the
minimum level).
