This is my first Busa that I have ever ridden. I just gave my wife my R1. Let me just say how impressed I am by this bike. From what everyone said I thought it was going to be a dog in the corners. I am impressed at how easy this thing turns into the corners for being such a big bike. And this is coming from a previous R1 owner. And it accelerates effortlessly. I really love this bike and I am glad I made the switch. The only small complaint that I have is that it is pretty buzzy at about 5000 rpm. I am sure that it will get better as I get some miles on it. I went for a 150 mile ride today and was smiling the whole time. Now it is time for the moddin to begin!!!
