I don't think you have heard the FZ07 ... it sounds actually pretty good .... opposed to BMW F800 par. twins, especially with an aftermarket pipe.
BTW what exactly are you comparing the FZ07 to??? I am just curious.
I was pretty surprised at how good the FZ07 sounded with the Akrapovic pipe. I normally hate the sound of parallel twins and this one actually sounds good. I was a little disappointed to hear that the R3 wasn't going to be a 270 degree crank. Oh well, can't win them all I guess.
