After the revolution Honda CB 750, it was in 1972 that Kawasaki lays first brick of the race for power with its Z900. It is immediately a success that the machine confirms its reliability, both in everyday life than on circuits.

Compared to the Honda CB 750, it provides a larger engine thus more power (82 hp instead of 67), and more torque and argument, dual overhead camshafts. While keeping the 4 exhaust pipes traditional at the time (the devil pounds), it has a look of hell, especially in color Tobacco with its orange flames and black engine mat. The cooling fins of the breech but keep a sharp color aluminum. This dress will be taken over by the 750 Zéphir at its latest development. For practicality, the chain is lubricated from an oil tank located under the seat in the left side of the frame.

The machine will be distributed from 1972 to 1976 and each year suffer a slight change. In 1974, 900 Z1A is distributed with a new decoration (less beautiful than the original) and the engine loses its matte black paint. In 1975, technology evolves, the machine (Z1B) comes with a chain to O-rings, where abandoned oil pump. In 1976, the machine (A4 series) is now shipped standard with dual front disc.

In 1977, the machine disappears from the catalog of the manufacturer, victim of the war to the power it has triggered. It is replaced by the Z1000.
