The things that stand out to me are the Power to Weight Ratio and the 0-100 times. The GSX-R1000 is a rocket pure and simple. One Two ... your at 60mph, Three Four Five and your at 100mph.
The fastest bike I've ridden is the FJR1300, and it pulled like a freight train riding 2-up. The GSX-R750 is faster.

And just for fun:
$1,000,000 McLaren F1 Road Car
0-60: 3.2sec
0-100: 6.3sec
1/4 mile: 11.1 sec
So the GSX-R750 is in the same league as one of the fastest production cars ever built, and the GSX-R1000 is quite a bit faster.
