1969  

Development of the "Z1" had begun in 196x, but when Honda released their CB750 it crossed all of Kawasaki`s plans. Now it had to be something even bigger, stronger and faster. So deplacement was increased to 903cm which was 66mm stroke and bore. The countershaft was placed in needle bearings, two overhead camshafts throned on the massive block and four elegant mufflers . .
