I owned a previous model 09 ZX10 brand new. Was horrified upon first oil change, "low pressure oil Warning" lamp was on for 3 minutes, starving upper engine of oil! Turns out ZX6's, EX500's and Vulcan's also have problems pumping oil after oil changes. I also discovered my bike was pulling to the right because poor engineering allowed a .60th of an inch gap, causing forks to bend in, causing fork seals and bushings to wear premarturely. This also caused bike to pull to the right. All and all, Kawasaki's make great performing bikes but as far as quality and reliability, fit and finish, I would never recommend anybody buying Kawasakis. Kawasaki Consumer services were also nasty and mean, hung up the phone on me. Not to mention this new 2011 model there is a tech hold and rumor has it bad rings and cylinders wear our prematurely. Doesn't surprise me as kawasaki's are the worse bikes in my opinion.
