Total Crash Protection Pack for Kawasaki Ninja 400 2018-2023
Total Crash Protection Pack for Kawasaki Ninja 400 2018-2023
No one wants to field test crash protection, but am happy to day that these worked amazingly. Got run off the road into a construction wall, and aside from a chewed up clutch lever and some road rash on the fairings my bike is back in action.
