  • Primary Drive 520 ORH Gold X-Ring Chain

    Primary Drive Chain and Sprocket Kit

    This kit is awesome. Fit completely up to my bike with no issues. This was the first time that I have bought a chain and sprocket kit that I did not have to take links out of the chain. It comes ready for your ride. And the Steel sprockets are holding up well. The chain holds lube really well and rolls really nice. I have always ran other race chains and always took care of them but this chain seems to move freely and with ease. I race every weekend and ride trails and such during the week and I have only had to tighten my chain one time! Great product, great price and even better fit up.

  • DID 520 Chain

    DID 520 Chain

    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 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.
