What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2003 Kawasaki Ninja, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

I BELIEVE THAT THIS IS A DEFECTED MOTORCYCLE PART[ THIN HANDLE BARS ] THAT MY BODY WEIGHT COULD MAKE THEM BREAK WE HAVE FROM THE ER TO NIGHT THAT THERE HAS BEEN OTHER ACCIDENTS LIKE MINE CAUSED BY THE NINJA BIKES. THAT IS A DIFFIDENT DESIGN DEFECT. *NLM
