Keep in mind that ET is largely a function of the launch, and from a roll that all changes. Bikes hook hard off the line, even on street tires, so from a stop that would change the picture. How much horsepower/weight you have is much more important once the tires are hooking, and that's relative to trap speed. And I don't think a 750 is all that much faster than a 600, if at all. I don't see any reason to doubt rbatson either.
