What year is my cb 550 please

(1/4) > >>

Rolfbulmer:
Hi guys,
I have recently acquired a honda cb550F.
The V5 says it was registered in 1979.
The frame No. is CB550F-2113328
Engine No. is CB550E-1153025
My research makes me think it is an F3 from 1977
Could anybody please let me know if this is correct. Also does it look like the frame and engine are 'matching'.

Nurse Julie:
Welcome to the Forum. If its an original 1st registered UK bike (ie, not a USA import) it can't be a F3 as we only ever had F1 and F2 in the UK model range. Also, if it is a UK model, its no good looking at USA engine / VIN numbers, which is what is generally found on the Internet. Is it an import or a 1st registered UK bike?

deltarider:
There was no F3. It's an American 'invention': the US market is used to a new model every year, for marketing reasons, but Honda never produced a F3. If you want to identify your model exactly, there's p.4 in the Parts Lists: https://www.honda4fun.com/dwnload/Part-List/CB550/CB550-F2-Parts-List.pdf

Bryanj:
Similarly it has to be late registered if 79 but there were a lot left in crates

Rolfbulmer:
Thanks for the replies.
Nurse Julie: I believe it is a first registered UK bike.
Deltarider: thanks for the link - It would appear that the frame and engine number could be any of the options on the list on page 4, so confusing for me.
Bryanj: Yes, I thought that also, all adds to my confusion.
