I have a few bikes in my stable, all late models R1, gsxr full road race over 30k in bike, and now the ZX, my race bike has a Kyle racing motor with 10k in it and I must say the ZX would give it a run for its $$$$$ power wise. I have had over 10 bikes in the last 4 years and the ZX is hands down the best, you could race this bike STOCK out of the box and do well. The thing is so far ahead of the rest it is not even funny.....
