Welcome. I have a little Italian beauty in my stable.
5 speed, 6 speed. It all depends on the gear ratios. My Voyager has 6 speeds and you can't get into 6th until you are on the interstate. My Versys has 6 speeds and I am in 6th at 40 mph.
Out of the Sport Touring bikes with drive shaft, the Concours is the most sport oriented. Many here do risers and cruiser seats, etc. to make it more Goldwing like. Some of us prefer the sportier riding position.
I recommend you test ride as many as you can. Don't forget the Norge, Trophy, and Beemer's offerings when you are test riding.
