I think you are too late Steve - just followed the link and they are sold out
I have tried various chains over the years and keep coming back to Renthal. Their R3 is currently favourite. I have a couple of mates that I ride with regularly. WR450F and CM604 - and they seem to eat chains compared to the TTR. The bikes are used "enthusiastically" and the R3s seem to outlast all the others.
The chains come with both a split and a rivet link and a handy pair of gloves to keep your hands clean whilst doing the replacement
DID X rings are availble at about the same price.
I will be interested in what other owners think.

PS A simple mod that doubled the life of my chains was to put the chain guard back on and take off the front sprocket cover where earth and stones build up and rub on the chain

Thanks Brian, I was afraid that may happen if I didn't get in quick, Oh well, bad luck
I'm still a little unsure about chain size though, when it says 520, there isn't anymore measurements like link length or whatever ?
so I would just have to order a R3-2 O-Ring Chain and that would fit ?
also when you say the chain guard, you mean the one that sits on top of the swing arm ?
If so Bugger, my bike did't come with one, the front sprocket cover is a good tip though, when I got the bike the whole area was packed with dirt and sludgy stuff, not any more though.
Thanks
Steve

A 520 O ring is all you need to look for - you can always see if you can beat the prices here
There are some very cheap O ring chains available occasionally on eBay but the experience of a couple of Devon TRF members who tried them is that they are a waste of money and wore out very quickly.
The chain guard is the black plastic part that attaches to a couple of tabs on the top of the swing arm. As the rear wheel goes around in mud and grit, it will deposit a good helping of the clag right onto a bare chain which then immediately feeds it into the front sprocket - unlesss you have the guard fitted. The blue TTRs had a longer and more effective guard than the white ones.
Regarding chain and sprockets, it is always a good idea to change them as set but expect that two front sprockets will be needed for one chain and rear sprocket as they work so much harder. It is also a good idea to buy an extra split link to carry on the lanes and fit it when you put on the 2nd sprocket as the spring link wears with use and can ping off if left too long! That's one reason I stick to the same make and type of chain so that I don't have to faff around getting a spare split link at chain change time.
