Production of the 73 model Z2 finished in October to be replaced by new Z2A model. Manufacture started in November (frame number Z2F03688) so that official sales could commence for January 1974.
As to be expected, changes to the model closely followed that of Z1 to Z1A, and accordingly the bike looked like a 750cc Z1A, for example the Z2A got the Z1A type tachometer and warning light cover. In fact all of the Z1A changes were applied to the Z2A, the only difference being that the Z2A engine remained painted black. This was a feature that was to stay throughout the life of the model. Clearly the Japanese biking public liked their black engines.
The model went on sale for 448000 Yen but was only made available to the Japanese market in the Candy Green with White/yellow stripe option. It is interesting to note that in the Z2A parts book the brown/orange version (2E code) is listed, so for those with deep pockets, the option of buying the 2E parts & standing out in the crowd was a possibility. The only other noticeable change was that the rear dampers reverted back to the customary red reflector type that we all associate with the (USA) Z1. The speed warning set up remained the same, but the additional wiring required (as mentioned on the Z2 page) was now incorporated into the instrument loom (Z2A Part No: 25011-044)
Production continued throughout 1974 until around February 1975 where at this time that things become a little bit messy regarding model designation. While the rest of the world was witnessing the demise of the Z1A and birth of the Z1B, in the Japanese market this change of model designation never happened for the Z2 range and so accordingly the Z2A model continued through to the same time (approximately) as that of the change to the Z900, that is, there never was a Z2B model.
It is not entirely clear why Kawasaki chose not to re-brand their model, but reference is made in most Japanese publications to a change of model during Jan / Feb / March 1975 with the accepted cut off frame number in the region of Z2F10336. Some publications do refer to the new model as a Z2B while others do not, but since KHI officially do not, I will refer to this bike as the 1975 model Z2A.
