Kawasaki Motors Corp., U.S.A. (KMC) has announced a recall affecting a select range of its motorcycles, specifically the 2023-2024 ZX400S and ZX400P models. This recall, identified under NHTSA Campaign Number 24V221000, includes the 2023 Ninja ZX-4RR KRT Edition, as well as the 2024 Ninja ZX-4R and ZX-4RR models. The core issue prompting this recall is the potential damage to the motorcycles' spark plugs, which occurred during the manufacturing process.

Risk and Safety Concerns

The damage to the spark plugs can lead to several operational issues for the affected motorcycles, including unstable idling, hesitation during acceleration, and the risk of engine stalling. Such engine failures are critical as they significantly increase the risk of accidents, posing a direct threat to rider safety.

What Went Wrong?

According to the recall documentation, a tool used to tighten the spark plugs during installation may have been tilted, applying lateral force on the spark plugs, causing them to crack.

Details of the Recall Plan

In response to these concerns, KMC is offering a remedy to owners of the impacted motorcycles by proposing to replace all four spark plugs at no additional charge. Although the schedule for this recall's notification process has not yet been outlined, motorcycle owners can reach out to KMC customer service at 1-866-802-9381 for further information and assistance. KMC's reference number for this recall is MC27-04.
