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 unreasonabl

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.
