I got to ride a friends 2006 GSXR 1000 this last weekend. Man is that thing a machine. It feels real light and its pretty comfortable. The last gixxer I rode was an 96 750 and I didnt think that was very comfortable. The only complaint that I had about it was the tires. It has a Battleaxe on it and it makes it feel real tippy to me. I only drove it for about 20 minutes but when I was done, I didnt want to get off. Very NICE bike.
