I can't comment on stock tire mileage because I picked up a screw and replaced both the front and rear tires at 600 miles with Dunlop 208's. I barley got 3,000 miles on the last rear tire. Had to limp home from a day trip when I noticed thread showing through. I replaced both the front and rear at that time because I'm stupid and have too much money. I'm watching the current rear tire carefully, and I'm going to order a new set on the web well before it wears out.
I'd love to order the Metzler Sportec M-1p for the busa, but there was a serious recall on the front tire a while back, the only sportbike tire recall I've ever heard of, and a serious one, where the front tire blows. Imagine that at 160 mph.
