Power trainCrash
This issue has been documented on hundreds of KAWASAKI NINJA400 Motorcycles ranging from 2019 to 2023. The clutch will malfunction and slip with miles as low as 200. I personally have a ninja 400 from the dealership with 7000 miles on it and the clutch is indeed slipping abnormally and this has almost caused me in many times to loose control as it creates a very unpredictable situation. for many drivers. This needs to be recalled as kawasaki is avoiding this due to the âcostsâ. This is unacceptable please do your investigation into this further as to see how notorious this problem actually is and how unsafe of a situation it creates to to the general public.
