Try to arrange your luggage or heavy accessories in the lowest possible position and close to motorcycle centre. Be sure to secure the luggage to the supports provided on the motorcycle as firmly as possible. Improperly secured luggage may affect stability. Never fix bulky or heavy objects to the handlebar or to the front mud guard as this would affect stability and cause danger. Do not insert any objects you may need to carry into the gaps of the frame as these may foul moving parts. If you install the side panniers (available from Ducati Spare Parts Department): sort luggage and accessories so to distribute weight evenly and then arrange them in the panniers so that they are well balanced; lock both side panniers using the suitable key lock. Make sure the tyres are inflated to the proper pressure indicated at page 86 and that they are in good condition. E 9
