A super heavy-duty non-sealed chain for small-displacement street bikes and mid-size off-road racing — JT rates the 520 HDS to 350cc street and 600cc motocross use. Non-sealed, solid-bush construction with riveted bushes shrugs off repeated shock loading and keeps rolling drag low; it needs regular lubrication rather than relying on sealed-in grease. Heat-treated pins and side plates deliver roughly 8,860 lb tensile strength — a step up from the HDR line. Pre-stretched at the factory so initial slack stabilizes quickly during break-in. Ships with a clip-type connecting link (a rivet link is sold on this page). Spec: type: chain · pitch: 520 · length_links: 120 · finish: gold-black Fitment Universal fit — works on any compatible motorcycle.
Available lengths: 116, 118, 120, 124 links. Finishes: Gold, Gold & Black, Natural. Replacement master links available on this page: Rivet.
