The first Z900?s came out in the USA in the May of 1972 known as the ?New York steak?. The Z1 were officially out in the UK in 1972-73 and had a distinct black engine, it came in candy brown/orange or candy green/yellow, in 1974 it was known as the Z1A came in the same colours with a different style but now with a silver finished engine, in 1975 the Z1B was produced and was very similar to the Z1A apart from a colour change, it was candy super blue or candy super red and lastly in 1976 the Z900A4 was produced which came out in diamond green or diamond brown but with a braking upgrade as it had twin disks up front, the earlier models all had the lugs on the forks, the twin disk was an expensive option, all variations had a drum rear brakes and this was the end of the run before the Z1000A1 was produced this came out with rear disk brake, twin disks up front and the exhaust was changed from a 4 into 4, to a 4 into 2.

As the Kawasaki Z900 was starting to gain competition in the form of bigger motorcycles, Kawasaki had no option but to increase the capacity of the big four from 903cc to 1015cc. This was achieved by increasing the bore of the cylinders from 66mm to 70mm. Many enthusiasts mourned the passing of the original Z1 style motorcycles when Kawasaki increased the engine size from 903cc to 1015cc. Maybe it was the end of the glorious four into four exhaust system that did it, however the 1015cc motor was basically a progression of the same unit so these motorcycles are included in this website.


The first Z1000, known as the Z1000-A1, was introduced in 1977. It had a four into two exhaust system as standard. This was obviously cheaper for Kawasaki to produce than the four into four system used on the Z1-Z900 series. The Z1000-A1 retained the 26mm Mikuni carburetors, however, the increase in capacity enabled the engine to produce 83 bhp. The Z1000-A1 was available in Diamond Wine Red or Diamond Sky Blue, both with Gold pin striping. As with the Z900, the Z1000 had twin front disc brakes. The Z1000 had a rear disc brake in place of the drum brake that had been fitted to all of the 903cc variants. This was not always the better option. In the wet, the older style drum brake offered more confidence to the rider. The Z1000-A2, introduced in 1978, had the front brake callipers mounted behind the fork legs. The A2 was available in Luminous Green or Luminous Red, both with Gold stripes. U.S. models were also available in Black with Gold stripes. The instruments on the Z1000-A1 and A2 were the same as those on the Z900. The hazard warning light switch was redesigned and incorporated into the left handlebar switch unit.

The Kawasaki Z1000S was made by Kawasaki Germany in 1979 .The most noticeable differences between the Z1000S and Z1-R being the four into four exhaust, the 24 liter touring fuel tank, and the Z1000S bespoke badges.

The Z1000S kit was then offered to German Kawasaki dealers to retrofit onto customer bikes, however only 200-250 kits were distributed

In 1978, Kawasaki introduced the first Japanese custom 'cafe racer' Z1000-D1, better known as the Z1-R. This was a factory customised motorcycle featuring a small handlebar fairing, cast alloy wheels the front wheel was reduced to an eighteen inch one and a four into one exhaust system. The Z1-R had twin drilled disc brakes up front with a single drilled disc at the rear. It was the first of the Kawasaki’s to feature the new angular look. The Z1-R was finished in a light metallic blue described by Kawasaki as Metallic Stardust Silver. The kick-start pedal was considered redundant and fitted as an emergency measure under the seat. The front mudguard was also finished in this colour. The engine of the Z1-R was finished in black and was very similar to the early Z1. A return to 28mm carburetors enabled a power increase to 90 bhp making this the most powerful Z yet. The Kawasaki marketing team listened to dealer feedback and produced a larger 20-litre fuel tank and a sintered metal brake kit to compliment the Z1-R. In 1979, the Z1000-D2 was introduced. This was basically a MkII engined version of the Z1-R and featured a four into two exhaust and a nineteen inch front wheel. It was available in Ebony or Luminous Dark Red. The model was continued into 1980 as the Z1000-D3 when it was only available in Ebony.
