  • Primary Drive 520 ORH Gold X-Ring Chain

    Primary Drive 520 ORH Gold X-Ring Chain

    Joe in CA

    Good deal if you really, absolutely don’t have $50 ...

    I’m torn. First, it’s super cheap. Second, if you really maintain it, it’s sort of a good value. Third, it actually doesn’t stretch much. All these are goood things! But, it’s super heavy, too wide (rubs on aftermarket chain guide which means it’s WIDE), definitely has more rolling resistance than other xrings, and gets beat up and seemingly rusted quickly (used the same chemicals and cleaning regime on this chain as I have on DID narrow xring chains for years). All these things are bad. So, I’m still torn. Think I’ll pay the extra $50 some odd and go back to DID narrow Xring chains, especially on the 250F. 3 stars for me but 4 stars if you just want a cheap chain that should last.

    Better then stock on any bike.

    I was not sure if this would mount up without the plastic OEM sprocket cover. I did not want the stock cover because it traps mud and rocks. The TM replacement comes with new bolts and mounts in seconds without the OEM cover. PERFECT!!! Now if I have a mud ride or race I don’t have to worry about buildup in the front sprocket and more protection Incase of a chain break.

  • Primary Drive Steel Kit & Gold X-Ring Chain

    Primary Drive Steel Kit & Gold X-Ring Chain

    William in CO

    Had some doubts, because of the low price! BUT A FI...

    Very strong! I could feel the difference between the stock sprockets and chain and the primary drive parts! I really noticed on launching from a jump ,no outright chain slap, while lugging the motor you don't get that annoying chatter type sound!! Love this SET! I will be buying this recipe for my old XR TOO!!! P.S. NEED TO USE THE FAST TRACK 1MM SPACER ON COUNTER SHAFT SPROCKET! VIA CHAIN IS WIDER! WORKS PERFECTLY!!

    Looks great!

    Perfect fit! Looks great!! Has a quiet sound compared to the stock parts, I would always hear a little metal clank sound with the original! Not anymore!!
