Chain On Triumph Tiger 100P From 1972

[Serge1952]

Hello there
I want to change my chain on the final drive but do not know what chain to order as it is not mentioned in my workshop manual.
Can anyone help me out?
Thanks
Serge

You should have a parts book for your bike. The specification is on pages 5 and 35 - 5/8 inches x 3/8 inches (also known as 530), 102 links.

If you do not have a parts book - https://partsbooks.britishonly.com/partsbooks/20-10103C.pdf

In my experience, if you buy a Japanese make of chain (DID, RK, etc.), the nearest length is likely to be 110 links.

FWIW, I'm using a DID X-ring drive chain chain on my BSA B44. It fits perfectly and there is no rubbing anywhere. The X-ring allows the chain to be narrower, thus no rubbing.
I'm using a Renold 5/8 x 3/8 drive chain on my Triumph T100S which will not need to be replaced for some time, but when the time comes I'll look into the X-ring.
I think I'm correct in saying that the same drive chain is used on all the 500 models since about 1959/60.

There is only one make of 530 (5/8 x 3/8) O or X ring chain that will fit a Triumph; unfortunately, I cannot remember which make ...

The 3/8 inch part of the chain specification is the width of the sprocket, so O or X rings make the overall width of the chain - over the outer sideplates and pivot pin heads - greater than the same chain without 'rings'; Triumph was not particularly generous with space between the chain and surrounding non-moving parts.

I think I'm correct in saying that the same drive chain is used on all the 500 models since about 1959/60.

I have never come across a Triumph that was not fitted originally with a 5/8 x 3/8 chain. The only other possibility is perhaps 5/8 x 1/4 on some very low power models - Tiger Cub, Terrier, etc.?

Thanks Rudie. I wasn't going to make the leap for an X-ring chain for the T100S until I thought about it seriously. The current Renold chain is barley used so it wouldn't have been for a long while anyway.
I suspected that it might not fit the way it does on the BSA, and I'm quite happy to use a Renold chain.
