In November 2024 Kawasaki Motors Corp., U.S.A. filed safety recall '''24V-680''' covering approximately 1,150 U.S.-market 2024 Ninja 7 Hybrid ABS and Z7 Hybrid ABS motorcycles produced between November 29, 2023 and August 26, 2024. The defect described in the filing is that the shift-control ECU may unintentionally select neutral during a 1st-to-2nd upshift, causing a loss of drive power and increased crash risk.<ref name="nhtsa-573" /><ref name="advrider-recall">Adventure Rider, "Kawasaki Recalling Certain Ninja 7 Hybrid and Z7 Hybrid Motorcycles," 2024. https://www.advrider.com/kawasaki-recalling-certain-ninja-7-hybrid-and-z7-hybrid-motorcycles/</ref> The remedy in the recall is a software reflash of the ECU; no mechanical part is replaced.<ref name="mc24-13" /> | In November 2024 Kawasaki Motors Corp., U.S.A. filed safety recall '''24V-680''' covering approximately 1,150 U.S.-market 2024 Ninja 7 Hybrid ABS and Z7 Hybrid ABS motorcycles produced between November 29, 2023 and August 26, 2024.
