In owners' own words

Quoted from NHTSA's complaint file. These are unverified accounts by the people who filed them, not findings of fault.

ENGINE

1 death · crash · towed

Unknown. Fatal motorcycle accident. Based on the police report, one witness said he blew a tire and all witnesses state that he and the bike went airborn. The motorcycle was part of the group of ZX6R's recalled by Kawasaki though its since been salvaged. The officer at the scene confirmed the bikes tire was intact so there's some suspicion that something else happened such as other parts coming off of the bike or the wheel smoking such as if it had locked up.

Recall was issued for crankshaft bearing failure and recall was performed and completed. Kawasaki performed the inspection and repair, however kawasaki had failed to adequately fix the issue causing prolonged headaches and paying for something that is unsafe to opperate. All kawasaki is telling people is dont ride but not providing an adequate fix to make the bike safe again or theyre also refusing to buy the bikes back.

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.
