I saw a 2nd hand black CX500 this morning with the thought of purchasing as a rebuild project.



At first sight it looks like a CX500 but someone has put a larger nose cone on the front, leaving the original behind it. The handle bars looked more custom shape than I expected and the front brake cylinder was "round" and not rectangular.



I took the list of Frame numbers and Engine numbers along with me, just to make sure that things match up. The engine number CX500E- fell outside the range that was on my sheets.....so it was onto the Frame number to see if that shed some more light.



The Frame number started with GL500- so I've walked away from the deal until I can work out what's happened.



As I say....Looking at the bike it's a normal CX500E (except for the handle bars). Did frame numbers ever have GL500 codes? If there are another series of numbers that I've missed would someone post a link.



Is the GL500 frame the same as the CX500 Frame?



This could well be scrapped bike that has been rebuilt but I don't have the history.

I took this document CX-GL PartsFinderhelp from here: PartsFind



The Engine serial started with CX500E- (Wish I'd written it down now) but it was out of the range of the CX500B (Between Italy and Germany range)...where it says This type is not produced.



Then to have the Frame Serial begin with GL500 with no match to the Engine number at all.

If you had a picture of the bike and told us the frame number we could probably hunt it up.



When you say nose cone do you mean a fairing or a nacelle?



Here's the nacelle version which you're probably familiar with in the UK.

If there where ever frames with a GL500 serial number, then I'll try and get the owner to send the serials to me.



This was the advert picture







The original nacelle cone (as you've shown in your photo) is behind the larger cone.

Looks like a cx standard or deluxe frame to me.



It has the 78-80 cx front end on it.



And unless someone welded shock mounts on the rear it's a cx frame.



Under the tank on the cx frame it's a single tube backbone. On the gl it has 3 tubes.



In 81 both frames started with JH2.

It´s a Japanese bike. They were called GL 500 over there and both frame- and engine number say GL 500.....(with an E for Engine, of course).



There was no GL 500 (Silver Wing to us) that had anything else than PC02 as model code. Hence their frame- and engine No:s start with "PC02".



I have some sort of listing of the very few GL 500 (Jap) that have been "grey" imported to Sweden. Maybe interesting as a reference??



I´ll try to dig it up.

Hi,



This is an excerpt from a registry list of all CX/GL:s in Sweden some years ago.



The bikes below are those who didn´t fit into the models we know as regular imports (also 650 models, that were never imported here due to very unfavourable insurance classification).

It´s obvious that there is some discrepancy between year of manufacture (from frame number) and listed year model in the list above.



Some years ago I imported a German CX 500 standard with frame number, indicating manufacturing year 1981. Because it was listed as an -82 in Germany (well known for having many bikes listed as later year models), I had to argue with

the Swedish inspector a lot, to convince him the bike was in fact an -81, which he finally accepted.



All those GL 500 (standard model) I have seen (4 or 5) have had single front brake rotor/disc, round m/c fluid reservoir, black plastic radiator cowl (seems to have been painted silver on your bike).



The fact that "GL" was used for Japanese variants of many CX models as well as for the Silver Wing varieties has created some confusion. Not least for unwary owners or intending buyers.



I´ve seen grey/private import GL:s (manufactured 1978 or so) advertised as "Silver Wings" of later models. If you haven´t done your homework, it´s easy to get scammed.



I even pointed that out to a decently well reputed bike dealer who had one for sale when I visited his shop. He looked like I came from Mars and seemed to understand nada. The bike found a buyer shortly after. Hope he´s happoy with his "Silver Wing".

At last, can any one shed some light on these:



Frame Number : GL500-1001988

Engine Number : CX500E-2304910



So now I have questions:



Are the numbers even valid?

Does the Engine belong in this Frame?

What year should the bike be?

What model is this bike?



Is the bike suppose to be a CX500?



If anyone has an original picture of the bike that would also help (If not a standard CX500)



The results will be the deciding factor if this is going to become by restoration project.



The radiator was not painted silver, it's original crome and the reflectors have been stolen.

The easy part first:



Your engine is for a 1981 standard model. Only the standard model had the model code "CX500". The others had like PC011 (Custom), PC014 (Deluxe), PC02 (GL 500 Silver Wing), PC06 (Euro) etc, etc.... How does the crankcase vent look? One design for early models, another for the later ones.



"E" stands for "Engine" - therefore you´ll always/only find the letter "E" in engine numbers. The second digit tells which year the engine (or frame) was made - starting with "0" the first year of the model´s life (1978 for the standard model). "3" indicates the fourth year / 1981.



So - CX500E-2304910 would be a pretty early 1981 standard model CX 500 engine.



The frame number is more difficult. From my listing in an earlier post it seems that "GL 500" could mean the standard- as well as the Custom model.

You´ll have to check the actual bike. Headlamp nacelle, 18" rear wheel, large tank, big "sofa", , etc,, looking like the one in "Stitch":s post above - then the frame is from a Japanese CX 500 standard. Probably 1978, as the second digit in your frame number is "0". I believe they made them for the Japanese market too, from the very beginning (1978). But it´s more like guesswork, from my part. If your sidecover emblems say "Wing" instead of "CX 500" if fits the picture well.



I think, but can´t tell for sure, that your bike got a "new" engine instead of its original one. Not necessarily a bad thing..



We don´t know much about the Japanese variants of these bikes.

From the pic, it's a standard first year CX500. From info in the previous posts in this thread, it was probably a Japanese market bike, which aside from the frame numbering were almost identical to the US market bikes. That's an aftermarket mini fairing.



Are there any tags or stickers left on the bike, such as tire pressure, loading etc?



I recall some old posts out of South Africa about some very unique bikes being sold there, IIRC the CX Custom was available in SA as a "GL400", and the frame number started with "GL" even through it was marketed as a CX just about everywhere else.



South Africa has had unique vehicles built for it as far back as I can remember, in the "old days", people in the know would track down old Mercedes made to S. African specs, these cars had triple row radiators, heavy duty suspensions, special rear diff. ratio's etc. and lasted longer than the ones built for the rest of the world. Especially so in hostile environments where their price could be double what a "normal" Mercyless Benz sold for. Some real oddball engine/chassis combinations only found in SA too.



So, the bike could also be a model made specifically for the SA market, have you tried contacting Honda.za, or better yet, have a local Honda bike dealer check his fiche to see if he can shed any light on the numbers?

Oh, sorry!



Didn´t read all post back, when I did my latest one! So, it seems my posts are somewhat confusing. Info repeated and so forth...



Your bike has the -78 79 wheels, and is basically the same model as the one we recognise as CX 500 standard.



Sorry again!

First thank you all for you help, so here is an update....



I contacted David Silver Spares, Identify my model, this was an email that provided the same information as already posted here.



Tim Whiting from David Silver Spares replied with:



The frame number is that of a GL500 1978 Wing, Japanese home market model

The Engine is from a CX500B 1981 model



So thanks Tim.



On my way home from work I went via Honda, who are less than helpfull, would just say the Engine is a 81 model and wouldn't comment on the frame.



The outcome....



The bike has probably been either stolen and recovered with the Engine missing or some other fate perhaps a front end smash and the bike rebuilt using parts from various models. Even if I did take the bike and rebuilt it, I could have problems with Police clearance (Could take a day here, going from pillar to post) and then find they won't issue a clearance certificate. (If engine and frame numbers where OK this would be easier)



So I'm going to walk away from the deal and wait for the next one.



Thanks Cobram and Sture.



I'll be back.

Just so you know. Although the engine and frame numbers don't match as you said. The numbers on them won't match in the future either on any of these bikes. As the frame came down the line and the engines met up if the engine was ready to go it went into the frame. If it wasn't ready to go then the one that was ready went into the frame.

Very true, but this engine is 3 years newer than the rest of the bike. In the US we're kind of spoiled (well except for Kalifornia) in that the authorities could care less about engine swaps, especially so when the power plant is newer than the original. In most other countries it's a very different story, if chassis numbers don't match up with engine and transmission numbers, many times you're stuck with an uninsurable, unregisterable white elephant only useful for parts.

I agree on both counts. (Both above posts)



The current owner has not put the bike into his name, not paid license fees for the last year, regardless if the bike was a runner or not.



He mentioned when I saw it last week someone else was interested etc........but then as I left it was "Make me an offer". I could probably pick up this bike for $200 or less in sterling.....I could rebuild it and then get stuck with it! (Not that that might be a bad thing).



I'd rather pick up a bike, pay a little more but know the Egnine and frame are within the Honda ranges noted in the above postings, should I want to sell it etc, I know I won't have problems.



These bikes don't come around often.....but sometimes it pays to wait.

Does anyone know the length of the backbone from the neck to the bend on a CX500?

Hi. Does anyone know more about this Frame and Engine number. I'm assuming because it's a Cafe Racer and I'm in the UK it's a cx500 A. Any tips or pointers would help thanks. Obviously engine doesn't match the frame.

Frame Cx500-2010848 or 648... difficult too see.
Engine CX500E-2105877.

Thank you.
