At DMG Motorsports, we present the D.I.D SUPER 520NZ-114 Non O-Ring Chain (520NZX114FB) — a professional-grade, high-performance drive chain built for riders who demand serious strength without the drag of a sealed chain. Engineered by D.I.D, a name trusted across MX and Supercross paddocks worldwide, this 520-pitch, 114-link chain is the go-to upgrade for vintage machines and lighter-displacement bikes that were originally equipped with non O-ring chains. Whether you're lining up at the gate or just want a rock-solid replacement for your trail bike, this chain is built to take a beating and keep pulling hard, moto after moto.

The 520NZ's exclusive DHA pin treatment forms a hard chromium-carbide layer on the pin surface, delivering exceptional wear resistance and up to 19% higher tensile strength than conventional non O-ring chains. Combined with solid bushings, quad-riveted pins, and shot-peened components, this chain is designed to handle the punishment of aggressive acceleration and hard-charging riding without stretching or failing prematurely. It ships complete with a clip-style master link, so you can get it installed and ready to ride right out of the box.
