Limited data — recalls on file
NHTSA has just 6 complaints on file for the 2004 Kawasaki Ninja ZX-10R — too few to judge reliability from owner reports alone — but one recall campaign applies to this year, so any used example should have its VIN checked for completed recall work. Reports tied to this model year include one death, per the complaint records themselves.
