I got there at 8:45am, and signed up for the GSX750 at 12pm. Also signed up for the DRZ400SM at 4pm, which is the one I really wanted to try, but I had to leave and couldn't make it back, so i called in to cancel it.
The 750 is pretty awesome. Very smooth, linear throttle. I had a bit of trouble with the clutch engagement point, but obviously that's fixed with an adjustment. Once I got the hang of it, I was riding it as comfortably as I ride my 250. First gear tops out at like 130, took it to 150 in 2nd before I had enough. Couldn't redline 2nd, LOL.
Gave it a WOT punch in 1st gear at one point and felt the front end go light and wobble, with the front tire getting squirmy. Interesting feeling! That bike would definitely wheelie very easily if I had a week with it. Brakes were phenomenal, they felt so nice and had great feel. Gave it a good jolt at one point, locking the front very slightly (coming up to a stoplight, no biggie), and it felt like I was going to go over the front! Obviously I wouldn't, but I'm just trying to convey how powerful those Brembos were.
Ergonomically fantastic, I felt very comfortable on it. Too bad there weren't any twisties, as I really would've liked to put that big piston fork through the works. On Heritage Rd., you could really feel the bumps in the road, suspension was very tight. As I would only ever get a SS for the track, I like that, but you would definitely want it softer for the streets.
The only things I didn't like about the bike was the fact that it got VERY hot in the legs (felt it through my 1pc and my boots), and that it seemed difficult to tip into "corners". What I mean is that sometimes, I'll swerve side to side in my own lane, and my 250 does this very easily and smoothly. The 750, I really had to force it to do it. However, this could be due to the steering damper, and it may just need to be turned down for my own tastes.
Awesome bike, but I'd never ride it on the street. That bike feels at home on the track, the street is an insult to its abilities. I still wish I could've tried the DRZ!
