D's X-Ring chain is designed for high performance motorcycles and Quads. Their patented X-Ring construction creates a chain that is both low in friction and high in wear resistance. Split link provides easy and quick fitment.In developing this new series, D. D focused on improving chain rigidity. Traditionally chain tensile strength has been used to indicate the overall strength and lock dirt out. They are expected to last at least ten times longer than standard chains without significant wear elongation under satisfactory maintenance. The chain length & size supplied is correct to fit the machine listed using standard sprockets (OEM), to be 100% certain please double check your number of links on your existing chain prior to ordering.
