1989 was the last year of production of the model, after which it was finally replaced by the [[Kawasaki_GPX600 | Kawasaki GPX600R]], which has been on the market since 1988. By the way, in the American market there was no division of models into GPZ and GPX - there both models bore the same name Ninja 600R, therefore, to distinguish American versions, it is recommended to compare the factory designation of models:

* '''Kawasaki GPZ600R''' (Ninja 600R) - ZX600A

* '''Kawasaki Ninja 600RX''' (with aluminum frame) - ZX600B
