The Regina ORE narrow O-ring chain is recommended for bikes where case clearance is an issue, such as the Honda CRF 450
Light and strong, the 520 ORE O-Ring sealed chains are engineered to withstand severe stress and provide superior wear resistance in all conditions seen by road or off-road riders
Extended bushings and solid rollers, alloy carbon steel pins, and shot peened plates offer increased tensile strength and fatigue resistance
Constructed with specially shaped bushings designed to eliminate the barrel distortion that occurs when a standard bushing is assembled
Exceptional surface hardness is achieved with a special chromizing treatment of the pins, translating into maximum wear resistance
