  • Renthal 520 R-1 Works Chain

    Renthal 520 R-1 Works Chain

    TOM in PA

    Stretched out alot quickly

    Maybe it's because I ride a 450 and ride alot and in the woods, but this chain sucks, it stretched out alot each ride, always had to tighten it and it only lasted about 4 weeks before it was stretched out way too much. Also it was barely lighter than the Primary Drive x ring chain that I went back to that last much much longer. Fast Vet A rider.

    Benjamin in OR

    Strong, light, looks good.

    This chain works awesome and it lasts for a long time. I milked it for 3 seasons, then used it as my dune chain. Its toast now, but I got more than what I paid for.

    Primary Drive 520 ORM O-Ring Chain

    Garrett in PA

    With steel sprockets, this combo is unbeatable!

    Longest lasting chain I've ever used. Unless you're a pro supercross racer, the extra weight won't kill you!

    skyler in CA

    Worth the money

    It is a great product for the price. It has lasted me over 4,000 miles. I run Baja with this chain. I have not even have seen any signs of wear. Never have to tighten the chain after use. Best chain I have had. I will buy others.

    Kevin in CO

    Worst chain ever

    I would say I got about 12 - 15 hrs of freeriding out of this. Maybe less. I have never had a chain die this fast. I mean my TM Racing 300MX is really powerful but this is ridiculous!
