I'm a function over form guy. I've drag raced on 2 wheels at Norwalk. I never got the drag racing bug, but if I did and I thought I could do better w/ext swingarm...I would probably do it. I don't get when people do it for looks, it's like bringing the custom chopper factor to sportbikes. Sportbikes are purpose built. Why have the committed riding position of a sportbike but eliminate the handling capability that comes with it? I don't get it, but I don't get custom choppers either. And no, you can't corner just was well with an extended swingarm. That's just physics.
