I have the earlier version, the Bandit 1250. Pretty much the same bike except for the fairing and instrument panel, the blacked out engine, a second radiator fan (to deal with the heat trapped by the full fairing) and slightly stronger fork springs (to deal with the extra weight of the fairing and fan).
I love it. It is an absolute blast to ride, and pulls stronger than any bike I've ever owned. There are plenty of smaller aftermarket cans available, and most of them are reasonably quiet, some can be very quiet (The Holeshot with dbkiller, which I have, and the Delkevic with it's insert, for two). For sport touring, you'll probably want to replace or Spencerize the saddle, and possibly add bar risers or taller bars and a taller windshield. There are many aftermarket shields for the '07 through '09 Bandit, but probably not yet for the 2011 FA. (I'm guessing the shields are not interchangeable, but haven't actually compared.) Assuming it's the same as the 07-09, to add bar risers you'll probably need to replace the brake line from the master cylinder with a longer one.
There are lots of aftermarket parts available, including Givi and Suzuki branded bags, performance and suspension parts, seats, etc.
Unless you're totally enamored of the styling of the 2011, you might consider a left-over '09 GSX1250SA Bandit. Essentially the same bike, and probably $3,000 to $4,000 cheaper. The Bandit was available with or without ABS ($500 price difference), the 2011 FA has ABS standard. Color matched fairing lowers are available for the Bandit.
