Which part number to order

DELETED as I do not want to mislead anyone.
This is the correct R3 cam chain. I think the other model Triumphs may use a smaller chain in link number. I would disregard all sources that suggest they are interchangeable.

thats what we use in the transmissions.
So Borg-Warner 'Morse' cam chains, would you put them in our R3s instead of the stock roller chain and would they match the same with our Roller chain sprockets?

I have a set of APE ACST2300 - Triumph Rocket Three alloy adjustable timing cam gears too and will have to check compatability with BW 'Morse' chain.

The chains r very strong they r pulling the vehicles. They would have to have matching cam gears and crank gear.
There r many different chains.
One popular one is a double chain that looks like the pic u posted.
Some have round pins and some have d pins.
