I've ridden just about every sport bike there is...
The Hyabusa isn't any faster than the other front runners up to 120mph, in some cases it's slower. Plus, it corners like a slug in comparison to the Yamaha R1 and Suzuki GSXR1000. You sort of have to "throw" it into the corners due to it's weight. I currently ride a Triumph 955i Daytona, so I'm used to the whole cornering like a slug thing.
However, after that Hyabusa hits 120, it just keeps right on pulling like a freight train up to 200mph and is as smooth as a sewing machine all the way on up. I'd venture to say it's the fastest bike from 120mph to top speed and definitely the smoothest and most solid at those speeds.
I liked it. I liked it a lot.
