Hello, I recently purchased a 2012 Ninja 1000. I have worked for a Kawasaki dealer for 6 years now and when this bike rolled in I had to have it, like new with only 1300 miles. The previous owner installed a Brocks alien head full system and a power commander v. The pipe is a little loud for my liking, I guess I'm just getting old . I have had a couple other kawasaki's over the years, I sadly had to sell my ZRX1100 to afford this one, but it was well worth it. As I am sure ya'll know it blows my old ZRX away. I have ridden a ton of bikes but I can't think of any other bike I would rather have simply for the comfort, speed, and look of this bike.
