The problem with a turbocharger is the lag. I have a Sonic 1.4L Turbo, it's got some kick but you can really feel the turbo come in.
People have complained quite a bit about Honda's VFR800 with vvti coming up 'on the cam' so to speak, pretty abruptly which is dangerous in a turn. Honda says with the new Interceptor this is softened up a bit.
It is very difficult to smooth out turbo lag. I rode the Honda CX650 Turbo back in 1984 and it was damn fast, especially for a 650 twin.
Superchargers are a little different situation, they are more linear, but certainly all these bikes are along the lines of the FZ-09 in mission; they haul ass in a straight line but will be handed a big can of whoop-ass in the turns.
Prolly the best overall package for turning and handling in all of motorcycling is the Street Triple R 675; it's got the most desirable combination of real-world handling, power, riding position, and geometry.
It ain't a racebike but in the canyons it's a great handler and will give anything a run for it's money and then some.
I'd still (I think I did!) take the FZ8 as an overall bike as it doesn't give up much at all in terms of handling but is a bigger, more comfy bike while still being well under 500 lbs.
The point of all this is that turbocharged and supercharged bikes cannot put that power to the ground in a turn anyway, and they will certainly be equipped with advanced traction and wheelie controls (something the FZ-09 could have used but let's toss that bolt-up frame first and get it some good suspension!).
