Ok guys, so I bought an 01 426 about 5 months ago and the guy tha I bought it from put the clip on the master link on backwards so that a rock could pop the clip off. I rode it untill now and would like to get a new link and clip. So I know the chain is an RK and it has o-rings but do not know if it is an x ring or just an o-ring chain. There is a number engraved into the chain and it is either X501 or Xs01. Most likely X501 though is what it looks to me. Any imput on what chain this is will be much appreciated. Thanks all.
