Well first off only the GSXR is mine, I have ridden the R1 and its no joke. Its one fast machine, the R1 is not even broke in all the way and it screams.
We ran them a little and it was random who would pull into the lead. I am about 40 lbs heavier than my buddy, but my bike does have -1 tooth down in the front and a full yoshimura system, although it hasnt been on a dyno to be tuned.
All I can say is I am very impressed, we switched bikes and of course with me being heavier on the R1 the GSXR just ran away, but when we were both on out own bikes It was damn near neck and neck.
I am buying a house, otherwise I would be very tempted to pick up one in Blue.
You guys that are getting the new R1's are going to like it. Awesome bike.
