Here is my situation:I am 6' about 210lbs with a 30" inseam.
I came from V-twin with a desire to get into the sport bike arena.
I had ridden a Buell so the FJR was my first "sport" bike experience.
I chose it with the fear that a pure sport bike would be hard on my butt and hands with lots of wind.
The FJR is a sport-touring bike. The jump betwen an FJR and a GSXR1000 is about the difference betwen the FJR and a Goldwing.
The GSXR1000 is a sport bike. It's tiny, light, very fast and optimized for track use. I'm selling my GSXR1000 because it's too frustrating to ride on the street. The riding position is too track-oriented and the performance envelope is so great that you use about 10% of the bike on the street.
I figure that even on a track, I can only ride the GSXR at about 40%-50% of the bike's capabilities. The thing is a monster. At 110mph, knee-down, shifting my body weight lets the rear tire spin up. At 120mph it still lifts the front end coming out of turns. Of course, I never set my GSXR up for track use, so I'm a bit reluctant to push it as hard as my track-only ZX-6R. Even so, the GSXR is sooooo beyond my capabilities it's silly.
On the street, I just find the bike just too frustrating to ride. I'd rather get something more comfortable that I can commute on. I'm 5'8 and 160lbs with a 29" inseam, so I'm quite a bit smaller than you. I find the bike really, really uncomfortable. Fine for a 15-30 minute track session, but too painful for street riding. The GSXR1000 does have the lowest seat height of any liter bike, so you may like that. Your height will lessen your reach to the bars compared to me, but you'll be in the wind more.
Compared to the other liter bikes, the GSXR1000 is widely regarded as the best (see Motorcycle Online for the first comparo of the '06 superbikes). But in truth, the bikes are all so similar it comes down to rider skill -- and on the street where the speeds are so far below the performance capabilities of any liter bike, just ignore the performance specs and get what you like (you'll never fully use the bike anyways). The one thing that would make me choose a GSXR or ZX10R over the CBR or R1 is that the Suzuki and Kawasaki have slipper clutches and the Honda and Yamaha don't. For an average trackday rider like me, the slipper really makes it easier to get set up for a turn when you're slowing down from 160+mph.
Here's a pic of me gingerly tip-toeing the bike around the track (I'm too poor to push a bike with OEM plastics hard on the track).
