Back after my test ride, and I've made a decision.
I got to ride a Ninja 650r, GSXR-600, and the ZX-6R; all 2012 year models. I'll list my immediate impressions as a new rider below.
Out of the three my favorite was the ZX-6R. It seemed to have a better mid-range than the GSXR-600, and once you get it over about 6-8k rpms you better be holding on. The 650R was far better for cruising around and normal accelerating (i.e. getting to highway speeds in a normal manner) seemed far easier. Much like with a Super-Car, with a Super-Sport you are either accelerating slowly or far too fast for the road. Although I feel you'd get use to it, and it would soon become easier to modulate with 100% precision. The GSXR-600 seemed to fair about the same as the ZX-6R, but the power seemed to kick in a bit later from my testing.
Wow! I thought my car stopped hard on pavement, all of these bikes have amazing brakes. Obviously the SS's have a higher initial bite, but all felt very linear on the road.
Again, I'm going to be limited by my impressions of these bikes as I had about 20 minutes of road use on each of them. From what I felt the 650r is better on the road, where its ability to turn sharper corners at low speed is useful. Both of the SS's are hard to manage around town, and obviously don't really like being there. I mean they can do it, but the entire time you are wishing you were on a track. Don't get me wrong, they are completely manageable, and you can if you wanted use them as a DD, but they are obviously far more at home on a circuit. I took all three bikes onto the highway, and threw a bit of power down on the on-ramp, and all three performed excellently. The 650R wasn't as responsive or fun to push as the SS's, and the SS's didn't seem much different here.
No contest, the 650R is the winner here. You are mashed onto the SS's and pushed as far down as possible to get the best control, while the 650R lets to sit up and look around.
So ultimately my decision came down to what I wanted from a bike. I already have a fast daily driver, so it isn't a quick spurt of speed and ability I was or am looking for. I've decided to get the ZX-6R for a number of reasons. I plan to track this bike, as I already track my car, and do motocross. Comfort isn't important to me, as I won't be using this bike to commute anywhere. So there, after much deliberation, research, and test rides, I'm getting the ZX-6R.
Thanks all for your suggestions, input, and help; I hope you all have a very merry holiday season.
