More about the Kawasaki Ninja
The first model to carry the Ninja name was the 1984 Gpz900R. Developed in secret over a six-year period, it was the first stock street bike to exceed 150 mph. The Gpz900R included technical advances for the day including the world’s first 16-valve liquid-cooled inline four-cylinder motorcycle engine, allowing for more power, and a frame that used the engine as a stressed member for improved handling and reduced weight. It was a marvel in its day and set the stage for all Ninjas that followed.
