Clutch system
If the control lever has excessive play and the transmission
snatches or jams when engaging a gear, then there is
probably air in the circuit. Contact a Ducati Dealer or
Authorized Workshop, who will check the system and
bleed the circuit.
Warning
The level of clutch fluid tends to increase in the
reservoir as the friction material on the clutch plates
wears out. Do not exceed the specified level (3 mm
above the minimum level).
