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.

GMy name is Duane Willett and I filed a Lemon Law claim Dec 8th and was referred to make a complaint to NHTSA by the Texas DMV.The vehicle is coming up on three months of non use due to the Manufacturer issued stop ride which was issued on two separate occasions. I purchased the 2025 Kawasaki ZX-6R vin number [XXX] brand new with zero miles [XXX] and its been subject to NHTSA's recall campaign number for this issue is 25V376 which the vehicle was not available to operate safely for over 30 days due to the #5 metal crankshaft bushing failure. Kawasaki is advised all owners of these bikes to immediately stop riding their affected 2024 through 2026 Ninja ZX-6Rs until the repairs could be completed. The manufacturers solution was not successful, failures continued and another recall was issued for the same problem. NHTSA's campaign number for this recall is 25V798. Bike was take to Family Powersports and the following are the technicians notes. 25-11 CRANKSHAFT BEARING SEIZURE INSPECTION Description SMC 25-11 CRANKSHAFT BEARING SEIZURE INSPECTION Resolution:E FAILED INSPECTION 3 SUPPOSED TO MEASURE 11.

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.

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.

Manufacturer communications
A bulletin sent by a manufacturer to its dealers. Not a recall, and repairs are not necessarily free.
ENGINE
2024 ~ 2025 ZX636J/K OIL & FILTER CHANGE (Factory Authorized Repair). This bulletin only applies to motorcycles that were eligible for recall MC25-08 and not repaired. Owners that did not have recall repairs completed under recall MC25-08 require an oil change under recall MC25-11.
Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
