I ride mostly desert trails on my 400-S. It's pretty much stock except for minor intake and exhaust mods. My chain and sprockets need replacement. I took a look at all the chains last night and figured I need a 520 112 link. I see DID and Renthal seems to have good ratings on their O-ring and X-ring chains. Any thoughts on these brands? What do you run? What tools do I need to install one of these chains? What chain tools should I be riding with as a minimum for longer loops in the desert? Thanks. See you out there.
