In Berlin I paid about 300 Euro for the 1year/15.000km service.
Now I got 23.000 on the bike and the 30.000/2 year service will cost me about 800Euro in Berlin.
But I asked an open dealer and he told me that the big service does cost nearly the same, does not matter if you go to ducati or to an open ducati store.
This was important because when I buy the 3-4 year warrenty I have to do the service at ducati official
