The D.I.D 420NZ3G72RB Super Non-O-Ring Chain is a lightweight, durable drive chain designed for powersports applications that use a 420 chain size. This gold-finished chain features 72 links and is built for reliable power transfer, smooth operation, and responsive performance on compatible motorcycles, dirt bikes, mini bikes, ATVs, and other small-displacement applications.
Manufactured by D.I.D, the 420NZ3G model uses a non-O-ring design that helps reduce rotating mass and friction compared with sealed chains. Its construction is well suited to riders and technicians seeking efficient drivetrain performance and dependable service in competition, recreational, or replacement applications. The gold finish adds corrosion resistance and a distinctive appearance when properly maintained.
Fitment depends on the vehicle manufacturer’s specified chain size, link count, gearing, and drivetrain configuration. Confirm that your application requires a 420 chain and a 72-link length before installation; additional links or adjustment may be required for certain sprocket combinations. For best results, install with compatible 420 sprockets and follow the vehicle and chain manufacturer’s lubrication, tension, and inspection procedures. The manufacturer part number is 420NZ3G72RB, and the vendor part number is 690-15072.
