you know whats even crazier!!!, the 07 gsxr750 is may be the fastest production motorcycle, lol. faster than even the zx14, if both were at last gear, and at redline, and totally stock, the 750 would be about .3mph faster!, now we all know the zx14 would get to top speed quicker, but its just crazy that the 750 is stock geared for a higher top speed! this is using the rear tire dimensions, and sprocket, and transmission ratios, and redline info for each bike, lol. 07 gsxr1000 top speed stock: 197.306 mph at redline 07 gsxr750 top speed stock: 206.405 mph at redline 09 zx14 top speed stock: 206.129 mph at redline
