Mother nature was nice and made for an awesome demo day. I have a new respect for Suzuki motorcycles after today. Granted I'm a noob not really ridden many bikes, but I now have a better appreciation for what will likely be my next bike.
Unbelievably, today I got to test several bikes each seemingly better than the next. I rode in the order listed, the Honda CBR600RRA, Suzuki GSX-R750, HAYABUSA, GSX1250FA ,GSX-R1000 and the GSX-R750 again to confirm.
End result if money were no object I'd probably buy a couple of these bikes or the BUSA if I could only choose one. I felt the BUSA was comfortable and refined ride. It made me think of a luxury sports car able to soak up all the bumps of the road, comfortable to ride for long trips and ready to become very aggressive if you so choose. Very excellent bike! Con is that it's a bigger bike and has weight to it when not moving.
The GSX1250FA, this bike was also good. Comfortable, had plenty of power, maneuverable but I can't say it was very fun. Excellent for long trips for sure but too much of a touring bike for me. Very practical, I must say.
The GSX-R1000, FUN FUN FUN and ohhh did I forget to say WOW! Unfortunately very impractical for everyday riding. Never really needed to get that thing out of second gear. Also felt a little sluggish to the point of stall in first gear at low rpm. Not very comfortable but I did strangely feel more comfortable on this bike than the GSXR750. Go figure.
Honda CBR600RRA was a good bike but after riding the others it really just did not compare. Imagine how I felt after getting back on my Ninja 250. LOL
Overall, I found the GSXR750 the most desirable of the bikes I tested and also very FUN!!! All the bikes ran pretty hot as you guys mentioned. The 750 seemed to run the hottest. That's probably because I found myself revving it more than the others from a pure fun factor. It was more maneuverable than the other bikes and I was playing with the A and B mode to see how the bike would go from Sport Mode to less Sport Mode riding. B mode probably could be compared to riding a 600cc bike. Overall not really noticeable for me other than maybe exhaust noise.
At this point I seem to be leaning toward the GSXR750 for my next bike regardless of my neck strain and numbness in my legs.

) I may just have to keep my 250 for commuting and the GSXR for everything else.
Highly recommend demo days when looking for the right bike! I will do it again.
