Well I raced a bike, but it wasn't a GSXR. I was on my way home from the track yesterday and happened to run into 4 bikes. One GSXR600, and 3 that were Ninja636s'. When I asked who was the fastest one guy stepped up to the plate immediately. It was one of the 636s'. We rolled 4 times from about 60mph. I was very surprised. The guy was an excellent rider and never missed a beat. Every time I would pull up a little bit up to 110mph then he would come back up beside me and usually get the nose until about 125mph. That's the top of my forth gear due to my 3.55 gears. After that I think I would start to pull away if we kept going. He had a very strong 3rd gear and seemed to flatten out some after that. I think I may have done better with stock gears, but it was awesome anyway.
