No....but I've read the the Driven product line from RMATVMC is pretty good stuff, plus it is priced right!
I have on for my EC200 after the rebuild is complete.
I went non o ring 520x120 links.
I hate to admit I'm still running the original o-ring chain that came on my bike. 2nd set of sprockets though
I don't get to ride as much as I wish I could (obviously). I bought this bike new and it's the first that had an o-ring chain, I think I'll stick with the o-ring. But that's worked well for me.
As info, I use chain wax as apposed to a lube. And never pressure-wash.
