In summary, the Ninja 400 could be described as the perfect entry into the supersport world. You can't get more power with A2, the looks suggest much more power, the vehicle is playful to ride, is forgiving in every respect and still allows a really sporty riding style. Those who had legitimate concerns about the lack of power on the various 250 cubic machines now have no more excuses. Ninja 400, it's good to have you!
