Ducati MULTISTRADA 1100 S Use And Maintenance Manual page 10

Arrange your luggage or heavy accessories in the lowest
possible position and as close to centre of the motorcycle
as possible.
Secure the luggage firmly to the motorcycle structure.
Luggage incorrectly secured may cause the motorcycle
to become unstable.
Never attach bulky or heavy objects to the top yoke or front
mudguard, as this would cause dangerous instability.
E
Do not insert objects into gaps in the frame, where they
could interfere with moving parts.
When fitting panniers (available from the Ducati parts
service):
arrange personal effects and accessories according to
weight and distribute them evenly in both panniers;
lock the panniers with the key provided.
Make sure the tyres are inflated to the proper pressure
indicated at page 78 and that they are in good condition.
