Just read enough to understand, as we all often do, is asking for justification to support our bias. I can't give you that, sorry, as to the Duc or probably BMW, not even a contest, the BMW. I'd say it much like comparing a jeep to a full size truck, a hot rod to a sedan. The Duc will out perform the Beemer on the street. I've owned both manufactured bikes, not the ones in question here but had the badges.
Buying a bike is an emotional experience, the less you really know about them the more emotional it will be. Pick what you like.
But, from a subjective point of view: How long have these models been on the road? How dependable are they" How successful is the design the bike, the engine and parts? How is dealer service, will you be waiting for a week for a turn indicator to be shipped in or are parts really in inventory at a dealership? How easy is it to work on while on the road or out in the boonies? Is there after market gear made for the bike or are we to fabricate things to attach items. How do bags fit, what can they hold, who makes them? How many models have been sold of each, what's the popularity? Which one has the better history of endurance, reliability and success for the type of riding you'll really be doing? What's the range of these bikes on a tank full? I'd think from all of these aspects, it's hands down the Beemer. Are you riding in Italy or Africa? The more common a machine is the more parts there will be available, the more mechanics too.
If you want sex appeal for your bike sitting outside the café or bar, want 0-60 check flapping acceleration the Beemer might not be it, but I had more gals want to ride my Beemer than all my other bikes excluding cruisers and Harley chicks.
Corbin makes pretty good seats, better than most stock saddles, I wouldn't buy a bike because of the seat alone.
If you want a proven dual sport, you won't go wrong with a Beemer. Resale will be higher too with a Beemer, that says something about demand of those who actually ride.
Enjoy your Ducati.
