I loved the Ducati Multistrada Gran Turismo. I had the dealer down to $18,000 on a leftover and backed out thinking I'd rather keep my 2 Concours' instead of losing both of them for the one bike.
Of the 3 in your choices. I would go with the Indian Chieftan.
And since you are in this direction take a good look at the Victory Cross Tour (the better American tourer), and the Moto Guzzi California line is awesome. They have Custom and Touring and two newer models called Eldorado and Audace. All shaft drives too. Even the Griso 8V SE is a sick bike.
