  • DID 520 Chain

    Nick in AZ

    DID chain did not last

    I purchased this as an extra, longer chain to occasionally run a paddle tire in the dunes on a 2021 KX450. I usually run an oring chain, but have used non-oring in the past. I could usually get a few trips out of a non-ring with proper maintenance and trusted that D.I.D makes quality stuff. However, this chain was by far the worst I have ever used. I had to re-adjust it after every ride during my trip, and I could not get it to stop stretching. Despite constant adjustments, it stretched so far that it damaged my paddle and the frame on my new bike. It also destroyed my new sprockets. This chain has less than 4.5 hrs of run time on it and it's not serviceable at all. Additionally, I'll have to replace all my drive components prematurely because of this chain. This may work on a smaller machine or in a less abrasive riding environment, but this chain was an expensive learning lesson for me.

  • Primary Drive 520 ORH Gold X-Ring Chain

    Staci in OR

    Durable product.

    It's gold. Lmao. But it's a good, durable chain for a great price. Does the job even if it doesn't match anything else on the bike.

  • Primary Drive 520 ORH X-Ring Chain

    DAN in UT

    WIDER THAN OEM

    Appears to fit 2008 CRF250X but haven't been able to look for interference with the crankcase cover yet. However, the stock DID chain (not available) width is18.5mm. The Primary Drive I installed is 20.90mm. This measurement is made on the pins, end to end. I believe DID makes a chain with the same width as the OEM.
