If you're a US-based rider and you've recently bought a 2024 or 2025 Kawasaki Ninja ZX-6R, I'm afraid that Kawasaki Motors Corporation USA has some bad news for you. The company is recalling 2024 and 2025 Ninja ZX-6Rs, including the 40th Anniversary Edition and KRT liveries, due to the possibility of the engine seizing while in use. An engine seizure while riding could clearly increase the risk of a crash and possible injury.
Approximately 17,792 Ninja ZX-6Rs in total could potentially be affected, which represents around 1% of the population according to Kawasaki's records. Potentially affected Ninja ZX-6Rs were produced between April 3, 2023 and April 28, 2025.
What's the issue? The #5 metal crankshaft bushing may be damaged due to overtorquing of the bolts that hold the crankshaft together within the crank case of affected motorcycle units. There is no warning that may occur prior to this potentially serious problem presenting itself, according to Kawasaki.
