How about having a peek at that new Suzuki GSX-S1000F or something similar. Similar in nature to the Ninja 1000SX (which my wife rides); which still gives you a more upright position (it's considered a "standard" rather than a sport bike); lots of room for your legs; but also lots of power, light, sporty, and super appropriate for touring and commuting.
As a past cruiser guy (including an H.D. Roadking); I find my back is a lot happier on a sport type bike. Another style could possibly be a naked bike (I was previously on a Triumph Speed Triple); but I prefer having a fairing for touring purposes.
