Ninja 400 (2018-2024)
The Kawasaki Ninja 400 is a sports motorcycle in production from 2018. The 400 model was brought in to replace the Ninja 300 as it struggled to pass Euro 4 emission standards compliance. All of our motorbike exhaust ranges are available for the Ninja 400 motorcycle models and in a variety of exhaust sleeve lengths, giving you the option to really personalise your ride.
Transform your Kawasaki Ninja 400 parallel twin to emit a rich and distinct sound with one of these exhausts...
