What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Handlebar became rusty and snapped off. Seems to be common among 2007 ninja 250s.
Tl* the contact owns a 2007 kawasaki ex250. The contact stated that the mounting screw punctured the left side of the fuel tank. Upon investigation, the contact linked the failure to nhtsa campaign number: 07v003000 (fuel system, gasoline).
My husband, an experienced rider, was ridding home from work on our 2007 kawasaki ninja ex 250. As he started up our driveway the throttle stuck resulting in his crashing the bike and breaking his ankle. This failure had occurred at least 2 other times, at least once during the break in period.
The lower engine mounting bolt nut had apparently loosened from vibration, and at some point actually fell off. The nut is not secured (does not use a cotter key or any other method to prevent backing off).
Brand new motorcycle had a oil leak which cause me to nearly have a major accident on the a freeway and nearly die. I spoke with an attorney who advised me this is a common problem on the model of my bike but kawasaki has done none to fix the problem.
