Manufacturers spend hours in the design of bikes, test bed monitoring, in order to achieve recommendations for owners.
synthetic is great ONCE your bike has been run in, but before that mineral oils should be used, as per their recommendations.
stick to what the book says and you cant go wrong !!

Fair enough, but it's best to actually read the book first or you can put your foot in it!
According to "the book" by which I mean the Owners Manual for my ST4S and the Factory Workshop Manual for the same beast, the recommended oil is Shell Advance Ultra 4
If you then go on to read it in full you will see that although the standard oil mentioned is 10W-40, it is also permissible to use 15W-50 providing that the average ambient temperature does not drop below -7 Centigrade.
So unless you live in Central Europe or other such cold areas, using 15W - 50 Shell Advance Ultra 4 is something that Ducati are quite happy with.....
10W-40 is only needed for temperatures below an average of -7 Centigrade.
Accurate information sometimes baffles bullshitters.........
