A sports tourer type motorcycle sold by Kawasaki in 1984. An American in Kawasaki's North American sales department said of the GPZ900R, "Oh, it looks like a Ninja!

For this reason, Kawasaki equipped the GPZ900R with a newly developed liquid-cooled four-cylinder engine that is lighter and more compact, with the aim of improving athletic performance. New technologies were introduced one after another, such as a full fairing that suppressed aerodynamic drag, which was revolutionary at the time, and GPZ1100 easily surpassed its predecessor, which had excellent horsepower, in overall performance The new technologies used in the GPZ900R not only laid the foundation for Kawasaki's subsequent high-performance motorcycles, but also greatly influenced the technical direction of many subsequent supersport models, making it a milestone machine that opened the door to the modern supersport era. The product was sold for 19 years from the start of sales in 1984 to the end of sales in 2003. It was also a machine loved by many fans for many years.
