I have a 2006 Limited Hayabusa with a little over 18,000 miles on it and can tell you it ranks as one of my favorite bikes of all time. It does everything well, from commuting, to canyon riding, to multi state 2 up trips and even track days. I had to modify the suspension for track day use (the forks are too soft) but beyond that it is fully capable of doing whatever you want it to do, comfortably. I don't know who the fool is that said it is slow (I don't care what kind of slow you are referring to either) but he obviously hasn't spent any real, objective time on a Hayabusa. I have a 2008 GSXR 1000 and as long as you have the revs up in the meat of the powerband it will outrun the Hayabusa by a little bit (with both being stock of cours). Never by much though. But ride two up and see what happens. I love all of the bikes I have in my stable, but the Hayabusa is definitely a bike the design team for Suzuki got right. Even out on the track it is extremely capable. It's bettter on fast, flowing tracks but it can still go pretty fast on tighter more technical tracks, you just have to be smooth. Keep in mind, most bikes today are better than most riders so it really just comes down to personal preference. My wife has told me under no circumstance am I allowed to get ride of the Hayabusa, unless of course I am buying a new Hayabusa. My FZ1, Bandit and GSXR 1000, she could care less about. Oh, with a full exhaust, intake came swap, airbox mods and some minor tuning an my Busa is pulling 174 hp to the rear wheel, while my pipe and tuned GSXR 100 is only laying down 161 hp. Where the 1000 doesn't start really running until 8,000 rpm, my Busa is pulling hard at 5,000 rpm. In the 1/4 mile my Busa is typically 9 mph faster than my 1000. Oh, my Hayabusa is typically in the 42-45 mpg range.
