Clutch system
E
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).
