  • DID 520 Chain

    DID 520 Chain

    Jesse in FL

    It works but stretches bad.

    Worked fine until after the first ride stretched. I thought its Okay its normal so I adjusted and rode again. Stretched again okay so I adjusted again. Rode it again and kept on stretching. This was all with 5 hours on the chain lol. I highly recommend getting a chain a little better if you have a built motor with a lot of power.

  • Primary Drive 520 ORH Gold X-Ring Chain

    Primary Drive 520 ORH Gold X-Ring Chain

    Trevor in UT


    This is an amazing chain! Fits well on my WR450 but I had to move the wheel in a fair amount with 15/50 gearing. The looks are one of the best features. I know aesthetics should not be a prime concern when choosing a chain, but it can't not hurt either :) I have wanted a quality x-chain for some time and decided to get one. I will be using x-chains from now on. This chain is quite and so far after about 50 miles of riding has not needed any adjustment.

  • Primary Drive 520 RDO O-Ring Chain

    Primary Drive 520 RDO O-Ring Chain

    false economy

    This was a cheap looking chain when I pulled it out of the box. Have never seen a chain with cut-outs in the side plates. It looked weak and sure enough it was. Every one of the inner plates cracked at the pin. This was on a DR350, not exactly a high HP chain abuser type of bike. Probably lucky in that respect because a more powerful bike might have broken the chain, which could have ended badly. Waste of money and potentially dangerous, I will never buy one of these chains again.

    Good O-Ring Chain

    I have used this chain on various bikes from wr450f, yz450f, wr250f, and drz400s. From the street to the dirt, through the mud, and back on the street this chains has held its own !
