Whilst awaiting the arrival of certain parts on the current resto, ive been reading various Topics on A4 A5s. Which started me wondering what is mine.
When i took possession of mine there was no paperwork only the Nova registration. I was informed it was a 76 A4, and the headstock stated 08/76.
Engine number Z1E-133420
Frame number Z1F-512431
However reading various articles it could be an A5 due to the late month of the build in 76. This is Confused .com, i know theyre basically the same, but what would DVLA assigne it to when i get it registered

The frame is a a5 from what littl knowledge I have

your frame number doesn't appear to listed in any of the z900a4 or a5 frame number range?

1977 KZ900-A5

KZ900-B1 LTD



Z1F-500001 through Z1F-510340 for bikes assembled in Lincoln Nebraska

THE KZ900 LTD FRAME NUMBERS RAN FROM KZ900B-500011 THROUGH 505514

Article from another forum, worth a read - re frame number.

A5 from the frame number as they started from 500001 as far as I know.

a5 frame numbers only exist up to Z1F-510340 & your frame number is beyond that

Thanksfor that Adrian, that makes interesting reading. If all A5 frame numbers range from 510341 -515578, that would make mine an A5 frame. I think! !!!!

as you can see the frame numbers are known, the specific numbers of the engines that were factory build in not, only the range is known.
