Regardless, the 750 is a great bike. I've had one of pretty much everything, and the GSXR750 didn't feel like too much of a compromise. 600s are gutless, but the 750 (to me, at least) leaned closer to a 1k than a 600 in seat-of-the-pants acceleration. Good choice of bike.
There are lots of professional moto journalists who have asked the question of whether litre bikes are now redundant, when 600s are now making over 130hp.
Maybe if we all lived in Germany and commuted on der autobahn, it would matter.
