The contact was unaware if any warning lights were illuminated. The vehicle was towed to a tow yard and deemed a total loss by the owner's insurance provider. A police report was filed, and injuries as well as a fatality were reported.
My 2025 Kawasaki Ninja ZX-6R ABS KRT Edition suffered a catastrophic engine failure at approximately 2,300 miles, resulting in a physical hole/breach in the engine crankcase and loss of engine oil. The motorcycle is currently at the selling Kawasaki dealer, Motorcycle Mall in [XXX].
The motorcycle is subject to multiple safety recalls related to crankshaft bearing/bushing seizure that can cause sudden engine stall and crash risk. In June 2025, Kawasaki issued Recall 25V376 and instructed owners not to ride the motorcycle until an authorized repair was completed.
Was notified by my local motorcycle store Classic Powersports of Rockwall TX that my motorcycle has been recalled for the second time in less than 3 months for possible engine failure and the manufacture has not remedy.
