Glen,My apologies, I must have misread your post. Will reread.
Yes I'm running 520 on two bikes to save a bit of weight. The sprocket wear rate is very high, might rethink it and switch them to 530.
Perhaps you can explain this part-
"yes I have a IWIS 530 motorcycle chain here and I would not fit it to a Commando even though It meets spec that was introduced long after the Commando was on sale."
Why would you not fit this chain?
Glen
It's too wide and very heavy.
The IWIS 10B Elite chain I use has been adjusted once in the last 5K miles, so why fit a heavier and wider product.
To clarify, the IWIS wassel 530 motorcycle spec chain soley produced for wassel is will be by design heavier than than either the JWIS or Elite chain.According to the IWIS specifications, although a whole 200 grams per metre heavier, the 10 B-1 M106SL overall width is (0.1mm) narrower than Elite.

Andy the original "Chain Man" didn't recommend the IWIS Elite as he considered it an inferior product to M106SL.

I know I bang on about this but having had just had another Enfield owner ring me and state that he has been told the Elite Brand "classic motor cycle chain" is made in Europe. Sorry it is not, it is made in China. I have no objection to people buying budget chain at budget prices but buying a...www.accessnorton.comChain

And I can confirm, at the cost of buying five Wassell Elite chains, that they fit no British bike I've tried them on without hitting something.To clarify, the IWIS wassel 530 motorcycle spec chain soley produced for wassel is will be by design heavier than than either the JWIS or Elite chain.
The specs for both the10-B IWIS Elite and 10B-1 JWIS chain are on the IWIS website.

Ya, since both AN and Wassell sell "Elite" chain and since I'm a Wassell dealer and can get their "Elite" chain for way less than AN, I bought 5. Eventually put them in the recycle bin. On an 850 even with two chaincase to crankcase gaskets the master link hit the inner chaincase sealing plate and with the master link installed from the outside in, was going to dig a groove in the gearbox. In a 74 Trident, the master link could not pass through no matter which way installed. On a 70 Bonneville almost worked scraped randomly.However, the chain sold by Wassell is called 'Elite'.

What are these Elite and IWIS 530 chains for then, Harley Davidson?
Can you explain more? IWIS = JWIS = AN ELITE = Wassell ELITE (but not the same as AN ELITE) - all in name, not specs.The rear chain listed by AN as IWIS 102 links 5/8 x 3/8 came yesterday. AN shipped ELITE 10B chain. It is not IWIS. I'm not sure if I should care. It'll fit between the gearbox and inner primary without any issues.

Why do you say it is 10B? Do you mean 10B-1? I AM NOT saying you're wrong, just trying to understand. I would love to know the width of the chain pins and the width of the master link pins. As long as a chain is nominally 5/8" pin-to-pin and 3/8" wide rollers only the overall width matters in whether it will fit a Norton without interference.
Interesting. Best I can tell, the 10B-1 master link spec is .839" so .835 is very close. All very confusing, but I think that is a JWIS chain, but AFAIK JWIS is another name for IWIS (an IWIS brand). At any rate, made by IWIS as is the Wassell ELITE chain which is much wider, especially at the master link which is .870".10B is stamped on the link plates under the word ELITE. I bought the chain from AN. It is listed incorrectly as IWIS.
I can tell by looking at it that it will fit on my Norton, which is not a Commando. I'll go measure it and get back to you, so you can determine if it would work on a Commando. Measured the master link pin width. It is .835"
I don't mean to spread incorrect information on the interweb, but it could be my superpower, and I can't stop it from happening.
AN shipped ELITE 10B chain. It is not IWIS.
Why do you say it is 10B? Do you mean 10B-1?
Thanks, I've been wondering if that was the case. At any rate, 10B-1 is the original drive chain for the Commando - correct?"-1" just indicates it's 10B simplex. 10B-2 is duplex, 10B-3 is...etc.
