2025 Kawasaki Ninja ZX-6r: engine stalls while driving

Filed Aug 30, 2026 · Engine · NJ

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 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.

My 2025 Kawasaki ZX-6R was recently included as a part of a federal recall concerning a defective crankshaft bearing. A critical engine component, the failure of which could lead to engine seizure, stalling or loss of power - posing a very serious risk and likelihood of a crash. After learning of this recall, I contacted my authorized dealer who confirmed that my VIN was affected, but advised me to CONTINUE RIDING, until I got a letter which would give more information on getting it repaired. I am currently unable to use the motorcycle as a mode of transportation or recreation, significantly affecting my mobility. Given the nature and severity of this defect, I do not accept any resolution that involves partial disassembly or reconstruction of the engine. That is not what I paid for when buying a new motorcycle. I believe the only fair and reasonable remedies are either: Option A: A full engine replacement with a new factory-built, unblemished engine installed by an authorized dealer, with a full reset of warranty coverage from the date of installation. Option B: A complete refund of the original purchase price of the motorcycle, including all dealer fees and taxes, while allowing me to retain title and possession of the bike given the substantial non-recoverable investment in modifications made in good faith." I have requested they confirm a resolution by July 10th and, according to '49 CFR Part 573', and whereby the federal safety agency interprets 'reasonable timeframe' as 60 days, that the remedy is completed by Aug 5th, 25.

I contacted Kawasaki customer care on two separate occasions via their chat option, copies of these interactions is included hereto whereby they proceeded to give conflicting responses that provided little to no information. I have also sent them a letter containing the following: "I am currently unable to use the motorcycle as a mode of transportation or recreation, significantly affecting my mobility. In addition, I have made over $9,000 in aftermarket modifications, which are rendered useless unless I’m willing to endanger my safety by ignoring the recall." and "Given the nature and severity of this defect, I do not accept any resolution that involves partial disassembly or reconstruction of the engine.
