On a slick with an expert rider running a 9.3Q, I expect 60mph to be coming up around 2 flat But, with a bike like this, it's tough to know, as they literally become rockets at about that speed. It might be running those times thanks to tall lower gears that hook it up, but sacrifice some lower speed numbers to make crazy higher speed acceleration.
With a Hayabusa specifically, it also depends on your tolerance for running into the red zone on the tach. The 1300 can rev much higher than the redline suggests, allowing a longer reach in the lower gears, which can chop those lower speed times.
