Storing the bike away
If the motorcycle is to be left unridden over long periods,
it is advisable to carry out the following operations before
storing it away:
clean the motorcycle;
drain the fuel from fuel tank;
pour a few drops of engine oil into the cylinders through
the spark plug seats, then crank the engine by hand a
few times so a protective film of oil will spread on
cylinder inner walls;
E
place the motorcycle on the paddock stand;
disconnect and remove the battery. Battery should be
checked and charged or replaced whenever the
motorcycle has been left unridden for over a month;
protect the motorcycle with a suitable canvas that will
protect paintwork and let condensate breathe out.
The canvas is available from Ducati Performance.
