History Behind the Lawsuit

Kawasaki Motors Corp., USA is facing a proposed class action lawsuit following a recall of thousands of 2025 KX450-series motorcycles over an alleged crankshaft defect that poses a serious crash risk. The lawsuit, Melendez v. Kawasaki Motors Corp., USA (Case No. 8:25-cv-00910), was filed on May 1, 2025, in California federal court.

According to the complaint, Kawasaki marketed the motorcycles as safe and effective while allegedly knowing that a faulty crankshaft primary gear could fail during operation. The crankshaft plays a critical role in converting piston movement into rotational motion. Plaintiffs claim that failure of this component can cause the engine to stall suddenly while riding, exposing riders to potentially life-threatening crash hazards.

Which Motorcycles Are Affected

The lawsuit follows a recall announced on April 24, 2025, by the U.S. Consumer Product Safety Commission (CPSC) involving approximately 3,400 motorcycles, including:

• 2025 Kawasaki KX450
• 2025 Kawasaki KX450SR
• 2025 Kawasaki KX450X

The recalled motorcycles were sold at authorized Kawasaki dealerships between June 2024 and March 2025, with prices ranging from $10,500 to $13,600. Affected units carry model numbers KX450MSFNN, KX450PSFNN, and KX450NSFNN.

The recall instructs owners to stop using the motorcycles immediately and contact a Kawasaki dealer for a free repair.

Claims Made by the Plaintiffs

Plaintiffs allege Kawasaki failed to adequately warn consumers about the defect and instead concealed or ignored the need for stronger safety warnings, allegedly prioritizing sales over rider safety.

The lawsuit argues that the motorcycles are “crash prone” and that no reasonable consumer would have purchased them had they known the vehicles were unsafe and susceptible to sudden engine failure. The case seeks class certification, damages, and other relief on behalf of all U.S. purchasers of affected 2025 KX450-series motorcycles.

What Kawasaki Owners Should Do Next

Owners of recalled motorcycles are urged to stop riding immediately, retain purchase records and recall notices, and arrange repairs through authorized Kawasaki dealers. Documentation may be important if the lawsuit expands or results in settlements or reimbursement programs.

Why You Should Consider Opting Out

While class actions may offer limited relief, individual claims often result in significantly higher compensation, particularly for riders who experienced dangerous stalls, near-misses, or extended downtime. Opting out preserves your right to pursue a claim based on your specific experience.

How Kawasaki Owners Can Take Back Control

While this class action lawsuit has begun, thousands of Kawasaki owners may be affected by the same alleged crankshaft defect, with many expressing frustration over safety risks and delayed remedies. These types of issues often lead to broader legal action, underscoring the importance of protecting consumer rights.

History Behind the Recall

In a rare move for the Japanese motorcycle giant, Kawasaki has issued one of its largest recalls in recent years, urging owners of the Ninja ZX-6R to stop riding immediately. Nearly 18,000 units of the popular supersport bike are affected, spanning 2024 and 2025 model years.

According to documents filed with the National Highway Traffic Safety Administration (NHTSA), the recall stems from a manufacturing defect involving over-torqued crankshaft bolts. This issue can lead to damage in the crankshaft bushing, potentially causing sudden engine failure during operation. Posing a serious safety risk for riders.

The Cause and the Consequences

Kawasaki reports that the crankshaft bolts in certain ZX-6R engines were tightened beyond specification at the factory, resulting in improper oil clearance and potential internal damage. If the bushing wears out or fails, the engine could lose power instantly, increasing the risk of a crash.

Given the potential for sudden loss of propulsion, Kawasaki has issued a strict “Do Not Ride” advisory until repairs are completed.

What Riders Need to Know

The recall covers Ninja ZX-6R, ZX-6R ABS, ZX-6R 40th Anniversary Edition, and ZX-6R KRT Edition motorcycles built between April 3, 2023, and April 28, 2025. While Kawasaki has confirmed the defect, the company has not yet announced an official repair remedy or VIN range for affected bikes.

Owners are urged to stop riding immediately and await further instructions from the manufacturer. Once available, repairs will be performed free of charge by authorized Kawasaki dealers.

How Kawasaki Owners Can Take Back Control

While this recall has been communicated to owners, many continue to be unhappy with the solutions provided by vehicle brands. These problems have the potential to escalate into further action, underlining the importance of protecting consumer rights.
