The Kawasaki Ninja 650 combines new aggressive looks with improved performance and livability. The Ninja 650 comes with some high-end components that don’t normally see on middleweights, such as an assist and slipper clutch, six-speed transmission with positive neutral finder, Kawasaki’s Air Management System (which redirects hot engine air down to the ground and away from the rider), semi-high-quality brakes, adjustable clutch and front brake levers, Kawasaki’s Horizontal Back-link suspension system (ala ZX-10R), and a gull-shaped swingarm.
