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.

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.

A recall has been issued and the motorcycle deemed unsafe to ride. My local dealership has been told to expect at minimum 3 weeks to receive the kit required to conduct the inspection. This issue has been so widespread that the wait time will be substantial. Even then, there will be a substantial loss of resale value as well as risk of further malfunctions after having a local mechanic disassemble and reassemble the engine.

I own a 2024 Kawasaki KRT ABS ZX6R. They want to do an inspection that will not be sufficient to ride my motorcycle safely. The absolute only way for Kawasaki to do that would be to open the engine up to where they could see the actual crank shaft. I feel we are all being jerked around with this. They won't be able to deem it safe simply by inspecting the outer bearing. My motorcycle doesn't even have 300 miles on it. I haven't been able to ride it for almost a month now. It sitting can cause further damage. I'm not sure if my State of Nevada will be one of the States that offer a refund. I am making payments on a motorcycle that I cannot ride. Which is unexceptable.

Manufacturer issued a Do Not Ride recall (25V376) but failed to provide a safe alternative or compensation. This has created a transportation hardship. I also felt very worried that I had been riding this motorcycle which had this serious issue. There is no timeline from the manufacturer on when the problem will be fixed. I'm extremely disappointed with this situation on a one year old bike. -thanks [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am submitting a formal safety complaint regarding my 2024 Kawasaki Ninja ZX‑6R. June 22, 2025, I received two official “Do Not Ride” letters from Kawasaki. These letters state that, due to a possible internal engine defect, the motorcycle is unsafe to operate. My authorized Kawasaki dealer has confirmed that my unit is affected by a manufacturing issue that can cause engine seizure without warning, leading to serious risk of crash, injury, or death. It’s also important to note that Kawasaki notified dealers of this issue on June 4, 2025—over two weeks ago. Despite this, I only received my first formal customer notice on June 22. In the meantime, I was unknowingly operating a potentially dangerous motorcycle. Kawasaki has not provided a fix, recall repair, or buyback option. The bike is currently parked and unusable, while I continue to incur insurance costs, loss of use, and storage burden. The issue appears to stem from an over-torqued crankshaft bolt or related internal engine component — a known problem on other 2024 ZX‑6R units already recalled. I am requesting that NHTSA investigate this case further and ensure all affected motorcycles — including those not yet officially listed by VIN — are promptly included in the recall campaign and made eligible for full safety repair, buyback or additional compensation.

I purchased a brand new 2024 Kawasaki ZX-6R. At just 3,500 miles, the engine catastrophically failed while I was riding. The bike seized and shut off suddenly without warning. This was months before Kawasaki issued their official “do not ride” notice for this known issue. I received no prior warning and had no opportunity to prevent the failure. The dealership confirmed the failure and linked it to a known internal defect affecting this model, which has since triggered a recall. My bike has now been sitting at the dealership for over 7 months with no resolution, no ETA, and no support from Kawasaki. Despite this being a critical safety issue, Kawasaki has offered no compensation, replacement, or meaningful update. I’ve been forced to continue paying insurance on a bike that was brand new and is now completely unusable. Their “do not ride” letter arrived after the engine was already blown. This is a serious manufacturer defect with real safety consequences. The lack of accountability and customer support is unacceptable.

As you are probably aware of this issue, there is a "do not ride" order in place for my 2024 Kawasaki ZX6R. The dealership confirmed that my VIN has been involved. I just got it, and I am paying for a motorcycle that cannot be used. The issues are below. This is unacceptable. safety recall report revealed certain vehicles may lose engine power during operation due to a seizure of the No. 5 metal crankshaft bushing leading to certain vehicles losing engine power and increasing the chance of a crash. "The bolts holding the crankshaft together in the crank case were over-torqued, and as a result the #5 metal crankshaft bushing can be damaged by improper oil clearance between the crankshaft and the bushing," a description of the issue read. Riders won't receive a warning before the potentially catastrophic issue arises, according to the document.
