2025 KAWASAKI NINJA ZX-6R Engine Problems

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.

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.

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. I've requested a buy back of the vehicle to purchase another model and I haven't received no response from the manufacture. I'm making payments on a brand new motorcycle that has possible engine ceasing while riding.

Currently the bike is under a "Do not ride" and is inoperable and will continue to be for an extended period of time for myself and many others, with no compensation or alternative during the downtime. Myself and many other riders are stuck with loan payments and/or insurance payments on a bike that is not even a year old in many cases with no word from the manufacturer other than the recommended fix we will be waiting in queue for. This fix is extremely damaging to our value of the $13000-$14000 many of us paid and it will be worth only a fraction of that to resale from here on. Not to mention the reliability of having our engine opened but local mechanics and serviced by them.

While riding at normal speed, I heard a loud popping noise from the engine, followed by immediate power loss. The motorcycle shut off without warning and coolant began leaking heavily near the front wheel. There were no warning lights or symptoms beforehand. The bike had fewer than 3,000 miles on it and was well maintained. I had to tow the motorcycle to the dealership, where a teardown revealed catastrophic engine failure—including internal damage to the crankcase, pistons, and transmission holder. The issue was later confirmed to be related to a manufacturer-issued recall, which had never been disclosed to me prior to the failure. Despite the severity of the issue and the recall connection, the dealership was unable to complete the repair for over two months due to parts delays and poor communication. The vehicle was non-operational the entire time. This failure created a serious safety risk and resulted in over $1,900 in financial losses due to towing, alternate transportation, and financing costs.

Told my 2025 ninja was unsafe to ride.

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 NHTSA interprets 'reasonable timeframe' as 60 days, that the remedy is completed by Aug 5th, 25.

Spent an hour waiting to talk to a Kawasaki rep and was told this about the 24/25 recall. "Currently, the recall affects all bikes. There is no current fix on the way BUT Kawasaki is confident (lol) that one will be on the way soon. Do not ride your zx6r for your own safety, but also because if the mechanical failure happens, your bike will take much much much longer to fix." People are spreading so much BS about this issue and a lot of it comes from being overly hopeful that maybe we all aren't screwed. Well, we are. This fix WILL affect every bike, or at the least every bike will need to be inspected, the recall is still not inbound to dealers, and even when it will be (like many have mentioned) this major repair will be done by some kid who's a technician at your local dealer...that's frightening in it of itself. I'm pissed about all this. I'm pissed I bought the bike 2 months before this, I'm pissed I won't have a rideable bike for maybe 6+ months and MOST OF ALL I'm pissed that this will forever be a huge black eye on my $13000 bike.The 24/25 ZX6R's will go down as the "BAD YEAR DONT BUY" bikes. That's the worst part. Even after the fix these bikes will all be bikes that have been cracked open for inspection/fixes. I've been living in limbo with this for weeks now going between hopeful, trying not to care and being angry that about the situation. People are rightfully extremely disgruntled owners of useless $13000 bikes that we just bought for right now. Riding season isn't year round for a lot of us. Anyway, hope I'm wrong. Hope the kawi rep I talked to is wrong. Hope this ends up being something that only affects 1% of the almost 18,000 25/25 ZX6r bikes even though I think we aren't getting accurate info from that document either.

2days after I bought this bike Kawasaki issued a stop sale and DNR due to faulty #5 crank bushing, and refused to buy the bike back but instead expected me to sit and pay payments and insurance on a bike that I can’t ride for possibly a year with no fix in mind so I had to trade it in and take a big loss on a brand new bike, kiss off Kawasaki that will be my last purchase from you.

Recall due to crankshaft bearing.

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 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.

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.

I have a 2025 kawasaki zx6r and I went into get my first service yesterday and they told me they just got a stop sales order from the manufacturer and that I will soon get a stop ride order in the mail and they didnt wanna service it since a recall is next. The issue is for a #5 crankshaft bushing failure.
