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]. This motorcycle is affected by Kawasaki/the federal safety agency safety recall campaigns involving the #5 crankshaft bushing and crankcase bolt loading, including the federal safety agency Recall 25V376 and the subsequent related recall 25V798 / Kawasaki MC25-11. Recall 25V376 had reportedly been performed before I purchased the motorcycle new on XXX. The motorcycle was subsequently subjected to the later recall remedy while I owned it. Kawasaki issued these recalls because insufficient oil clearance/excessive loading at the #5 crankshaft bushing could cause crankshaft seizure, engine stalling, and sudden loss of motive power. Despite the recall remedies, my engine suffered catastrophic internal failure and breached the crankcase. I am reporting this because the failure occurred after recall-related repairs and appears potentially related to the same engine/crankshaft defect addressed by the recalls. A sudden engine seizure or catastrophic engine failure on a motorcycle can cause loss of control, crash, serious injury, or death. I request that the federal safety agency investigate this as a possible post-recall remedy failure and evaluate the effectiveness of the recall repairs.

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?

This motorcycle has been recalled twice. The first recall my bike passed and was good to go. I received another letter about a 2nd recall. Was told it did not pass recall and is out of spec. I am now being told that my bike is passing kawasaki's new spec numbers for the recall. I do not feel safe riding a bike that was deem unsafe to ride and failing a recall. Now all of the sudden new numbers come up and is just aye okay to ride. How would is the consumer supposed to feel about this? A motorcycle is life or death.

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 can buy the motorcycle back from me for what I owe on it. I will not ride this bike untill the engine is replaces and a notorized letter stating that if I die my wife can sue Kawasaki if related to the recall and they will not dispute the lawsuit.

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.

Safety recall exists for engine stall risk but manufacturer has not provided parts or remedy for over two months. Motorcycle cannot be used.

I own a 2025 Kawasaki Ninja ZX-6R. 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. My motorcycle underwent the recall repair, which resulted in an extended loss of use of approximately two months. In November 2025, Kawasaki issued a second safety recall (25V798) stating that the prior repair may not have properly addressed the defect and again instructed owners not to ride the motorcycle. Kawasaki further stated that parts are not currently available and no repair timeline has been provided. As a result, my motorcycle has now been rendered unsafe and unusable on two separate occasions for the same defect, despite prior recall repair. I am continuing to make payments on a vehicle I am prohibited from operating, with no clear resolution or response from the manufacturer. I am submitting this complaint due to repeated safety-related defects, failed recall remedy, extended loss of use, and lack of manufacturer response.
