None of those are sport touring machines, and everything you have mentioned can get you in trouble really fast. You realize that those 600's are all putting out 100hp? Not gonna be highway friendly at all unless you are in the twisty bits..... think racebike friendly. Seriously consider what I have mentioned, might also look for an SV650 "they are stupid fun" and I doubt you would get bored with it. The FZ6 is comfortable, powerful, fast, smooth, and as reliable as a hammer. Have a friend that tours everywhere on his, and can really hit it hard when the road gets crooked. Something to think about is all, the supersports are race bikes with a headlight and turn-signals, and are not practical or smart for probably 80% of riders.
