Have you given any thought to some of the japanese twins, such as the TL1000R, RC51, or superhawk?
I own a 'Hawk and I love every minute of it. Very reliable, easy to ride, a ton of fun, and now that I have the new D&D pipes, it scares the shit out of people when I pull up to a light (Ok, so I like loud vehicles, so what? haha my first car was a camaro with a 454 big block in it.)
I am biased, because I was raised on american musclecars, so I love big sound. But if you want a bike with a very large usable powerband, you cant go wrong with some of these twins.
