The photo will be a handy reference, I also have a k0, UK bike but its in bits in the loft as I bought it to break for parts - for my younger cb500/4 but wound up deciding it's better left for a future restorer when I 're assemble it. I'll not tackle a restoration as the bank balance wouldn't stand that plus I prefer my bikes to look their age and not worry about them picking up a few marks or rust spots.
Got a 500/4 with rust and a sidecar and loadsa bits. nice and original and been round the clock

That's fantastic Trigger and something to aim for. I have the same engine crash bars and a period 'screen flow' topbox (think i'll give that a miss)
Should i rechrome the rims which are corrosion (and chrome) free, or go for new with stainless spokes? Now the questions have started ha ha.
 Huge gratitude for all your input. David M

The K0 in the picture was built as a usable bike, rebuilt the engine as the gear box had failed. The crash bars were a extra and the non STD parts are the stainless spokes, painted black hubs and the mirrors and it is still regularly in use today.

The vin quoted was probably BUILT in 11/71 as one starting 1048 was (US bike confirmed by vin plate)

That means it could be a late K0 or an early K1 as the model build year usually started late the year before so they could be on the sales floor early in the model year. My ID book gives start of model year numbers but i don't got it to hand

EDIT 2

Just found book, anything starting 1 is K0, 2 is K1 (starts 4/72), 21 is K2(unless in UK)

The VIN quoted is 1014 Bryan, I would put that in around May 1971 build. Out of interest as you have number 36, what is the VIN build on your bike mate.

No 36 was 2/71 and I misread the post number as 104 so 1013 was 5/71 and 1016 7/71 so yes may would be somewhere handy. Apologies for mistake, i had been awake 28 hours by then!!

Is this numbering scheme and dates only applicable to UK bikes?  If not, I'd like to throw my bike's numbers into the mix so to speak!

No it isn't just UK bikes, in fact later UK bikes are bloody awkward as they are all K1's made alongside K2's for the rest of the world and what looks like a 72/73 number is in fact 75/76.

Please add your details, obviously you wont have a build date only a registered date but I can give you an estimate of build date although with the new rolling 40 year exemption it is now getting a bit academic as all the 500's are over 40 years old except for maybe a few imported 500K3(which never was officially imported to UK)

Engine: 2153097
Frame:  2064562

Seems to suggest I have a K1 frame with a K2 engine, but I honestly have no idea how AUS bikes were originally set up.
There is no compliance plate on the steering yoke, but I believe these didn't come into play until 1973 in AUS.

I don't think you had a K2 in Australia ? So, the numbers worked the same as the UK. Frame 20 identifies it as a K1 and the Engine 21 is because it is a 1973, 1974 or 1975. Very common to see this and is original   ;)

Thanks for that Graham!  It's nice to know the bike isn't a "bitser"!
According to CMSNL's list, only the US got the K2.  I don't know how accurate that list is.  I imagine Bryan would have a pretty good idea though. :)

CMSNL's list is not perfect. For instance, there was a CB500K2 (ED, F, G) marketed in continental Europe in 1976 that is different from the earlier CB500K2 marketed in the US in 1973. Unfortunately CMSNL doesn't provide the fiches nor the Parts List, but... there's Honda4Fun that does: http://www.honda4fun.com/pdf_parts_list/pdf_spac500/CB500-76/CB500-76_1.pdf
When I compare the numbers you posted to the serial numbers on p.4 of that Parts List, yours is not a CB500K2 (ED, F, G). Nevertheless I thought it a good idea to inform readers there was such a model. At http://www.honda4fun.com/materiale-documentazione-tecnica/parts-list/parts-list-cb500 you'll find all CB500 Parts List. The serial engine- and frame numbers are in the first few pages of every list, so you can pick the right one. When you go through the list, there's the area code to observe. They are also listed in the first few pages of every list. The area code for Australia is "U".

Just out if interest Delta, do you own Honda4fun or work on a commission from them?, as you reference them regularly. I have rarely found anything on the site that I haven't been able to find elsewhere, and as with most other sites their information can be totally misleading at times.
Im a Nurse, trust me, this won't hurt.....much !!!

No, I don't own it and as far as I know nobody works on a commission. It's a site just like this here. IMO they're best in providing documentation. They have proved me to take this very serious from the beginning. What a strange question, if you allow me to say.

O, there's lots. Here's an example: scroll down http://www.honda4fun.com/home/faq/generali/111-cb500-differenze-k0-k1-k2 Apart from that, they offer the most comprehensive collection Parts Lists for the CB500/550 series. Most of them are in paper edition on my desk, btw. But maybe you're right. By now a lot must have been copied by others.

I'm confident you'll give us examples to substantiate you allegation. In the meanwhile can I be of any assistance with a specific question you have right now? Do you happen to  speak/read Italian? French maybe? I have a very good 100p. document about the CB500/550 in French. It's 163.879 kb however.
