Winning dyno plots are far from the only thing that makes a motorcycle fast. There's gearing, there's confidence, there's braking, there's chassis, there's suspension, there's wheel weights, there's mass centralisation or lack of it, there's geometry, there's the whole package... and some bikes have it more than others.
That said, you know why the S1000RR and CBR 1000RR (last two gens) are so great? Because the original bada$$ is the 05/6 GSX-R and they were built to beat it... frankly as streetbikes, they didn't do the job, although the Honda came close.
