I had a 2005 ZRX1200r (the last year offered in the US) and it was one of my favorite motorcycles of my 45 years of riding. It was a beast out of the box, but I uncorked it with a complete Muzzy Street comp header/exhaust, re-jetted carbs, a set of K & N filters and hotter ignition. After that it was a torque monster. I could barely keep the front wheel on the ground and roll on's pushed my eyeballs to back of my skull. I loved that bike.
