The Kawasaki Ninja 1000 SX (sold in certain business sectors as the Ninja 1000, Z1000S, or Z1000SX) and is a bike in the Ninja series from the Japanese producer Kawasaki sold starting around 2011. It is not related to the Ninja 1000R or any other Ninja motorcycle, other than its name.
The 1,043cc liquid-cooled, electronic fuel-injected, 16-valve four-stroke inline-four Ninja 1000 shares the same aluminum twin-tube backbone frame as the Z1000 streetfighter. However, it has ergonomics, storage, a larger fuel tank, and other design elements that are more geared toward the sport touring market. The Ninja 1000 also has an electronic speed limiter. This is not because it is capable of exceeding the 300 km/h but because its motorcycle fairings make it more aerodynamic than the naked version and they want to keep its speed the same as the Z100 model

The bike is being marketed by Kawasaki as a “sport bike for the real world.” The Ninja 1000 has an upright seating position, a large fuel tank, and an adjustable windscreen, as well as a transmission designed for street riding rather than racing.
However, it retains the large engine and aggressive styling of a sport bike, and its performance characteristics remain on the sport end of the spectrum, putting its sports-touring type more in competition with bikes like the Honda VFR1200F or Triumph Sprint GT rather than the Kawasaki’s Concours or Yamaha FJR1300.
