I had the new DVT to ride for 10 days out in Sardinia, and the engine is great but Urban mode is just dreadful! I found it far easier to ride in Sport mode than Urban, even in town!
Take the bike out and switch it into Sport or Touring mode, you'll find it much, much better. After a couple of days in Touring mode I switched it into Sport mode and left it like that. The only time it went back into Touring was to save fuel on a long motorway slog from one end of the island to the other.
Given that the bike is so new, I would expect that Ducati will release an update to the fuel maps to help smooth things out a bit and make Urban mode worth using.
