    Primary Drive 520 ORH Gold X-Ring Chain

    JEFF in CA

    really impressed

    Got this chain to replace my existing RK X-ring. Have put about 10 hours of moto and hare scrambles on it and am highly impressed. I maintain my chains well and they are always adjusted to correct specs. This chain got one very small adjustment after the first hour of riding and it hasn't changed since. It has been through some serious rocks and performs like a champ. The master link fit correctly and was easy to install. This is the only chain I will ever purchase from now on. It is a truly excellent value and matches well with the Primary Drive brand sprockets.

    Std chain 520 x 106

    This chain has no o-rings and is delivered with a clip-type master-link. I will install a rivet-type master-link asap. I will also take care not "sitting on the chain" i.e. verify tension with you seating on the bike, not when up on side-stand. There is a lot of difference. TECH NOTE: We recommend following the manufacturer specified chain adjustment procedure.

    Kyle in WA

    Great chain

    Doesn't stretch too quickly. I get the same life from these as I do the ERT2 which is more expensive.

    Master Link Issue

    I have heard good reviews on this chain and I installed one today. I am anxious to see how it performs in the long term. I will note that the U-Clip on the master link is thin and flimsy. I bent one trying to install it and it would not retain well as a result. Luckily, I ordered an extra master link and was able to get that one on ok. I hope this review is read and forwarded to Engineering/Mftg so that the U Clip can be improved by thickening it.
