I've got an 07 tiger. Almost bought an FZ6. The FZ1 is a great great bike. It makes a pretty good sport tourer too.

To me it seems the XR is kinda close to what you've already got. The Versys is a cool bike, and if I was going to have one bike (and couldn't afford my tiger) I'd consider it, but any one of those other bikes is going to be WAY more fun.

If you want a sport bike, get the daytona (Check out the ltd ed white with blue powder coated frame, gorgeous).

Other wise, I'd go Tiger or Fazer. Which ever fits you better.
