A new profile has been added to the list of Triumph motorcycle models on this site: The Rocket III Touring (2009-2015). No touring bike has had more effortless torque than the Rocket III Touring, with more grunt even at idle than most other touring bikes could muster at full chat.
It has a different state of tune to its Rocket III Roadster stable mate giving even more useable torque lower down the rev range. Capable of between 40 and 50 mpg you aren't going to be filling up the 24 litre tank all that often.
