Stock chain size is 100 links.
If you don't mind, though, I'll say your reason for wanting an x-ring chain, "I really hate constantly oiling it", isn't a strong one. No matter what chain you get the outside of the chain still needs to be cleaned and oiled just as often as a standard, non o-ring chain.
I used to run o-ring chains on my K1, but switched back to standard chain a few years ago. At $80+ per chain the longevity wasn't nearly enough when I can get a standard chain for $25.
