What chain do you guys use?

Car currently has a non o ring DID ERT3 chain and will be replacing it when I delete the chain tensioner. Just wondering if anyone else uses/recommends a o/x ring chain instead if so what are you using? Appreciate any input thanks!

In my D cars I use either Tsubaki sigma o-ring chain, or I think its DID that calls theirs an X-ring. I think they also have a "gold" brand as well. Most, if not all larger than F600 will be using a 630 chain, not sure if the smaller F600s use a smaller size link.

I can't think of a reason not to use a chain with seals. Granted, that doesn't guarantee the chain stays always lubed, but why not go for that extra protection?

Also, I think (and anyone feel free to correct me), most people lube their chains between sessions even if they are x/o-rings. At least that's the advice I've gotten.

Russ, I lube my chain between sessions as well. I also do an inspection for pitted, split, or missing rollers. Once any of those appear the chain is on borrowed time. It also gets a tension check between sessions too.

I use a DID 520 ZVM-X chain. Between sessions, I clean it and lube it with chain wax while it's still warm.

Lighter, cheaper, and less friction.

Trade off is they don't last as long.

I'll chime in as I've done both ends of the spectrum.

When I road raced a 125cc GP bike we ran very small chains, it was some crazy special size (418 I think) because the 3/4-1hp really did matter. The chains didn't last long.

When I had the DSR we started with a cheap 520 chain but they would be really loose by the end of a weekend. Going to a quality heavy duty O-ring chain solved the wear issue.

If I had to choose between the two extremes I'd give up a horsepower or two to have the longer maintenance intervals. If I were choosing a size I'd err on the side of larger. I'm also not ever going to be going to the RunOffs so I an afford to give up a little.
