Kawasaki Motors Corp., U.S.A. (Kawasaki) is recalling certain 2024-2025 Ninja ZX-6R motorcycles. The motorcycles may lose engine power during operation due to seizure of a metal crankshaft bushing.
An engine stall increases the risk of a crash.
Owners are advised not to ride their motorcycles until the repair has been completed. The #5 metal crankshaft bushing must be inspected on all eligible units already in operation. If there is no abnormality with or damage to the bushing, the bolts holding the crankshaft together in the crank case must be re-tightened with proper torque. If there is any abnormality with or damage to the bushing, the parts must be replaced and the crankshaft properly tightened, or the engine must be otherwise repaired or replaced. The manufacturer has not yet provided a schedule for recall notification. Owners may contact KMC customer service at 1-866-802-9381. This recall was replaced by 25V798.

Engine and engine cooling, Mar 5, 2026
See attached document for complaint. The undersigned is legal counsel representing XXXXXXXXXXX in the above-mentioned matter. Please be advised that XXXXXXXXXX purchased a new Kawasaki 2024 motorcycle model ZX636JRFBN on May 9, 2024 with total purchase price of $13,981.92. On or about April of 2025, XXXXXXXXXXX received a recall notice with follow up notice in June of 2025 NHTSA Recall No. 25V376 “Crankshaft Bearing Seizure” causing the engine to potentially “lose engine power unexpectedly due to a seizure of the #5 crankshaft bearing” that may lead to an increased risk of a crash. Given the nature of the recall, the notice is marked with a “DO NOT RIDE” advisory until the repair is made and that the customer is to contact a dealer for such repair. Sometime on or about late August of 2025, the motorcycle was inspected at a Kawasaki dealership in an effort to address the recall. This was the earliest that the dealership could address the recall nearly three months after getting the “DO NOT RIDE” notice. The mechanic who examined the motorcycle indicated that it did not appear that the bike had the defect. In November of 2025, an additional recall notice “Crankshaft Bushing Seizure” was issued under Recall # 25V798 since the notice acknowledges that a prior repair on the vehicle may not have addressed the defect. A second letter was issued in November of 2025 under the same recall notice indicating the parts needed for the repair are not available. Finally, another notice was issued under the same recall, 25V798. Again a “DO NOT RIDE” warning is issued on this notice. The letter advises that the “method used to torque the crankcase bolts will be different than the one used in the prior recall “and that the recall applies to “vehicles already remedied under recall campaign MC25-08 (NHSTA Recall #25V376). Once again there are instructions to contact a dealer for repairs. It is presumed that parts are now available to attempt another repair. Due to the critical safety issue relating to the recalls, the unreasonable amount of time, seven months since the first notice, XXXXXXXXXXX has not been able to operate his motorcycle. In fact it only has 1000 miles on it because of this inability to safely ride it. Further, now with this additional recall, it is the middle of winter in Upstate New York and my client has missed the motorcycle season rendering the bike useless through this lengthy repair and recall process that is still not remedied. Despite being unable to operate his new motorcycle, he continued to have automatic monthly payments to Kawasaki finance (Synchrony Bank) made of $137.57 per month on a vehicle that he cannot use. An additional $4776.48 remains owing under the finance agreement. Given this unreasonable length of time to remedy the defect under the recall and serious nature of the defect with a “Do Not Ride” warning, we ask that my client be compensated for the monthly payments under his finance agreement that he has incurred thus far since the recall ( $962.00) until which time the bike can be fully assessed and determined safe to ride and if it cannot , in addition the balance of the loan payout ($4776.48) . Should we be unable to reach an amicable solution, we will be prepared to invoke all rights and compensation as provided under the New York State Lemon Law. Please advise as soon as possible to avoid further action. Thank you.
