520 Chains

520 pitch drive chains from DID, RK and Regina. The 520 is the chain on every full size dirt bike.

Standard (non O ring) chains are lighter and cheaper and suit motocross. O ring and X ring chains keep their lube sealed in and last two to three times longer, which is what you want on an enduro or trail bike.

Chains come in 120 links; cut to the length on your swingarm sticker and fit the sprockets at the same time. Members pay the member price on every product in the store and get free standard shipping on orders over $10. Membership is $5 for the first month.

    Questions riders ask

    Every full size motocross and enduro bike: YZ125 up to YZ450F and WR, KTM 125 to 500, Husqvarna, GasGas, Honda CRF250R and 450R, Kawasaki KX250 and KX450, Suzuki RM-Z. Check the stamping on your current chain's side plate if you are not sure.

    Full size motocross bikes run 114 to 118 links, enduro bikes a little more, minis fewer. A 120 link chain cut down fits anything full size. The manual or the swingarm sticker gives the number.

    Standard for motocross: lighter, less drag, cheap to replace every few months. O ring or X ring for enduro, trail and anything that sees water, where it lasts far longer and needs less care.

    Not sure what fits? Set your bike at the top of the store and every list narrows to parts with confirmed fitment, or message us with your model and year.
