UNKNOWN OR OTHER
I am worried about my safety while riding this bike. There has been two different recalls associated with this bike. The first recall my bike passed and was deemed safe to ride. The second recall my bike failed and the dealer was in contact with kawasaki for a week. The dealership is now stating that since so many bikes were being failed, kawasaki had changed the spec numbers for the crank bearing. My bike is now passing the second recall after it already had failed. I do not feel safe getting on this bike. How is the consumer supposed to feel about this?

ENGINE
There has been two recalls on my motorcycle. My bike passed the first inspection, i took my bike in two weeks ago for the 2nd inspection, per my Kawaskai dealer my bike did not pass. They informed me that my bike required a new engine. On saturday I call my dealer and was told that Kawasaki re worded the recall fix solution and that my bike passed. My dealer said that the reworded statment makes no sense and that they would not trust the motor on this bike. So if the techs at the dealer are saying that this bike is unsafe to ride why should I just take that this bike is not affected by the recall when I was told it was. I request that Kawaskai replace the engine if they want replace it they

UNKNOWN OR OTHER
This is a follow-up to my prior complaint regarding my 2025 Kawasaki Ninja ZX-6R (VIN [XXX] ). In December 2025 I received another recall notice for Recall 25V798 stating that the prior recall repair may not have properly addressed the crankshaft bushing defect and again instructing that the motorcycle not be ridden. I attempted to schedule the repair but the dealer stated parts are unavailable with no timeline. The motorcycle remains unsafe and unusable despite prior recall remedy.

Where these numbers come from

A complaint is one owner's account and has not been verified by NHTSA or by us. A vehicle with more complaints is not necessarily worse: models that sold in larger numbers collect more of them. How this is counted.
