  • Primary Drive Rear Aluminum Sprocket

    Primary Drive Rear Aluminum Sprocket

    Dave in PA

    Surprisingly high quality

    Okay so here's the thing, I have a street legal KTM and it's tough to find a rear sprocket that gives me top end but still has juice through the woods. I'm running a 45 tooth and that fits the bill for my riding style. Honestly though, I'm worried that the aluminum construction won't last as long (duh) as a steel sprocket but I couldn't find a 45 in steel that fit my bike. For the price though, I won't be heartbroken if I go through a sprocket a season.

  • Sunstar Works Z Rear Sprocket

    Sunstar Works Z Rear Sprocket

    Rocky in New Jersey

    Sunstar Z

    I have 124 hours on this sprocket it is still not worn out, slightly heavier than aluminum. Because the Z sprocket is thinner than conventional sprockets I had some concern about chain wear, that was not a issue at all. Excellent sprocket.

    Slid right on

    Seems to be a decent sprocket. I threw it on an old KTM 520 to freshen it up a bit.

  • Renthal TwinRing Rear Sprocket

    Renthal TwinRing Rear Sprocket

    Matt in CA

    Good sprocket. Not sure I'd buy again tho.

    Great sprocket but fell recently and the sprocket hit a rock and the outer ring of the sprocket got knocked off the main portion of the sprocket. Had to remove the wheel and knock it back into place just so I could get home. Scrapped it after that. Previously used this sprocket on 3 different wheels.
