Oh, Fausto, I have ridden with R1's and Gixxers. They certainly can out corner me, however the Busa is much faster.
It may feel faster by the seat of your pants because of the torque, but the new Gixxer 1000 is faster through the 1/4 mile. Power to weight ratio.. The R1 is no slouch either.. I've owned a Blade (CBR900RR), ZX11 and now a R1. The R1 is definitely the fastest of the 3, but the ZX11 had the most torque and torque makes the bike feel faster, especially when you're not revving the bike.
It was sad that they clipped the wings on the Hyabusa and ZX12 when they were both trying to be the first bike to hit the 200 mph barrier for a production street bike. Actually, I'm not that sad that they killed the top speed because I don't spend that much time above 120 mph anyway on the street. You shouldn't either if you want to stay alive and keep your license. I do like that they continue to make the bikes faster to 186 mph..
I have been as fast as 197 mph.
Speedo indicated or actual? There's about 15 mph difference at those speeds due to speedo error.
A word about KM/H vs MP/H. I don't have any problem with the metric system. I've been learning both for most of my life now. The problem is that the US keeps holding onto MPH. If they'd switch over or at least start posting the speed limit in both, there would be no problem with me or most anyone switching over. It's just a pain to have to convert it in your head all the time when the signs are marked in mph.
