1976 KZ900
KZ900-A4 (Made in Japan) Frame Number Range: Z1F-85701 to Z1F-117060
KZ900-A4 ( Made in USA ) Frame Number Range: Z1F-500001 to Z1F-510340
The engine number range is the same for both (all engines were made in Japan): Z1E 086001 to Z1E 138846

​
1976 KZ900 began production June 1975 In Japan (9/75 for the American made KZ900, 10/75 European Z900)
Unlike the previous Z1 900 models the KZ900 was made in Japan and in USA's new assembly plant


Colors: Diamond Dark Green or Diamond Brown

The Fourth 900 model was re-designed and named the KZ900 (Z900 for Europe)


KZ900-A4 ( K for Kawasaki, Z for the Z model line, 900 size, A standard, 4 4th year of production)
​European Model Designation: Z900-A4 KZ was not used for any Kawasaki models sold in European countries. The "KZ" abbreviation was used as the German word Konzentrationslager (Concentration camps that operated in Nazi controlled Europe less than 25 years earlier). The European continent did not need to see "KZ" again.
All Kawasakis were badged with "Z" in Europe Z900, Z750, Z400 etc.


The KZ900 had a $2475 suggested retail price.

There was a KZ900 built in Japan and one built in the USA. The U.S. market received both, all other countries only got the Japanese made KZ900. Japan did not sell the KZ900 because the sale of motorcycles over 750cc were banned domestically.
The easiest way to tell them apart is by checking the frame number:
If the 6 digit frame number begins with 5, it was made in the USA.

​If it begins with 0 or 1, it was made in Japan.

1976 KZ900 (MADE IN JAPAN)
Frame Numbers Z1F-85701 to Z1F-117060
Engine numbers Z1E 086001 to Z1E 138846

Mass production began in August 1975 for the KZ900 (Production began October for the Z900, which had different features)


KZ900's made in Japan continued the frame numbering sequence of the Z1​
​The KZ900 made in Japan did not typically have close matching numbers like the Z1 because it was also made in USA's new assembly plant. All
 engines were assembled in Japan, when they were completed, some were loaded and sent to the US, while others were sent directly to the assembly lines. There was no specific frame/engine pairing sequence.
​

1976 KZ900 (Made in USA)
1976 KZ900-A4 frame numbers Z1F-500001 to Z1F-510340
​Engine Numbers Z1E 086001 to Z1E 138846


The U.S. made version of the KZ900 Started Production in September of 1975.
Frame identification tags have Made in USA and Frame numbers begin with the number 5

Since frames were in the 500,000 range and engines were a continuation of the Z1 Numbering system
Close matching numbers for the USA made KZ900 was never possible.


In October 1974 Kawasaki opened a new assembly plant in Lincoln, Nebraska.
Kawasaki became the first Japanese company to produce motorcycles in the USA.
Production began with the KZ400, First one rolling off the assembly line in January 1975. 9 months later came the KZ900.
 

All engines and most components were still made in Japan.
Parts were shipped to Kawasakis Factory in Lincoln, Nebraska for assembly with the U.S. made frames. 
Engines were shipped assembled. When they arrived,
 whichever engine was available was sent to the assembly line.
All Models (KZ900, KZ900 LTD & KZ900 Police) have the same (Z1E086001 to Z1E138846) engine range.


1977 KZ900-A5 Frame numbers Z1F-510341 to Z1F-515578
​Engine numbers went up to 
Z1E 138846

Assembled in Lincoln Nebraska 
September 15, 1977 NBC broadcast the first episode of C.H.I.P.S. Ponch and Jon (Erik Estrada & Larry Wilcox) rode the KZ900. Later in the TV series they rode the KZ1000. In one episode Ponch had a chance to win a brand new 1978 Z1R on Name Your Price, a parody of The Price is Right. Ponch's guess $3697 was $2 over the correct price & lost to a little old lady.
