Can a O or X ring chain be safely fitted to the 500 series bikes,
Or are we limited to standard DID heavy duty

I've had an O-ring chain on my 500 for many many years. However I think that may be because it's a dealer take off from a CBX550 I stripped right out of the crate.
It's not well known but the chains Honda fit although being DID chains are not the same as the DID chains they sell to the public, for some reason they are thinner. I had a mate who bought a OE chain for a CB1300, standard 50 chain, none of the 50 rivet links available on Ebay would fit this chain, all far too thick on the pins. A standard Honda rivet link needed to be ordered in order to use this chain, this was the first time I noticed this.
I still have the CBX550 chain lying around and I intend to measure it and see if it is indeed thinner than the same size chain available commercially.
I do know that DID for some unknown reason keep a massive stockpile of chains which were OE equipment, not sure why but possibly because they were specially ordered by the big 4 companies and they kept stock just in case.
As it turns out I bought the 1300 chain before he fitted it as he sold the bike instead. I'll see how it compares to the standard DID X ring chain in dimensions.
Oddjob:
Any dimensions on the DID heavy duty chain John.
I've found a chain and sprocket set in the loft for the 500, O-Ring version. It's stamped ES530 SDC.
I've also got a NOS OE chain for the CB650/CBX550, also O-Ring.
Let's see how your dimension compare to these.
Johnwebley:
It's a standard 530 chain,
I shall measure the width, and let you know tomorrow

I do know an out of the box aftermarket O ring 530 chain will rub into the blanking seal and crankcase on a 550, saw it a few times so it should do the same on a 500.
530hd chains of today are stronger than 530hd chains in the 70's
