Recently purchased a 2025 Kawasaki ninja ZX6R back in April 2025. Been riding and getting use to the bike.(absolutely love it) Got my 1st service done after break-in period just to see rumors of a possible recall on social media a week later. This was late May early June. Today is June 20th and i am just now receiving an Official notice from Kawasaki about the issue that’s been floating around for months. Very disappointed that i can’t ride the Bike and that im still stuck having to pay on the bike even though it’s currently in the DNR stage. Also there is no know possible fix. 1% of the 17.7k units are affected. Which if you do the math that’s roughly around 170-180 bikes. I would feel somewhat better if they could at least narrow it down to the VIN of the bikes that’s truly affected so that the ones who aren’t can enjoy the Bike they purchased. Kawasaki please handle this swiftly

I am the registered owner of a 2025 Kawasaki ZX-6R (VIN: [XXX] ), purchased in New Jersey and registered in Ohio. I am reporting a potentially dangerous engine defect related to the crankshaft bushing or internal bottom-end components. I have received credible information indicating that this model may suffer from premature crankshaft bushing failure, which can lead to catastrophic engine failure while riding. This poses an extreme safety risk to the rider, especially if it occurs at high speeds. I contacted a Kawasaki dealer, but they told me there are no active recall or service bulletins from Kawasaki regarding this issue. As a result, I cannot get the motorcycle inspected or repaired, and I am currently unable to ride it due to safety concerns. To make matters worse, it has come to my attention that Kawasaki has recently halted the sale of the 2025 ZX-6R in the U.S. market, which further suggests that there may be a serious defect the manufacturer is withholding from the public. I request that NHTSA investigate this matter and determine whether a safety recall is warranted before any serious injuries or fatalities occur. This issue affects not just mechanical integrity but rider safety at its core. Please advise on the next steps and acknowledge this report as soon as possible.

Complaint Summary: I purchased a brand-new 2025 Kawasaki Ninja ZX-6R ABS for approximately $15,000, and within one week of purchase, the bike was affected by a safety recall involving a potential engine seizure or rear wheel lockup. I was told by the dealership that the bike should not be ridden due to the severity of the issue. Since then, I have contacted the dealership three times. They have not provided a timeline for repair, no parts are available, and they offered no remedy — other than trying to upsell me another bike for $3,000 more. The motorcycle is not rideable, and I am essentially left with a useless vehicle and no resolution. Kawasaki has not provided a timely or effective fix, which I believe violates federal recall safety laws. I am requesting NHTSA intervene and escalate this issue so that Kawasaki provides a proper remedy, refund, or replacement.
