Sporting the same quality as all DID chains, the 520 ATV is a robust design with thicker plates for increased strength and heat dissipation. Perfect for hard on the throttle quads. Don’t worry about increased friction. With the "X" type sealing ring, friction is kept at bay with sealing surfaces that hold more lubrication in against the rollers and pins. With design like this, DID has made an ATV chain you’ll adjust once and then keep on your bike for seasons to come.
