Kawasaki Ninja 650R Street Sport

The key to the Kawasaki Ninja 650R's slender size is its compact liquid-cooled, fuel-injected, DOHC, 8-valve 649cc parallel twin engine, which permits the use of a narrow, lightweight frame. Fuel injection and ignition settings on this torquey engine are carefully chosen to boost bottom-end torque, smooth low-mid rpm response and allow it to rev more quickly.
