If you have a method of getting it down to you, and could return it in a week or two, I'd be willing to lend my CB550 out. I took my MC endorsement test on it, and it's damn near cheating compared to the 'busa.
It's only somewhat annoying mechanical issue is the front brake squeaks a bit. But, new tires, new brakes, fresh oil change, runs like a champion. It also sounds magical, the exhaust note and induction noise is a symphony of mechanical awesomeness. Unfortunately, it's about as slow as a Toyota Corolla!
