The ThreeD 520 MXR 3D Drive Chain is engineered for 125cc to 500cc motocross motorcycles that demand efficient power transfer and dependable performance. This non-sealed chain uses a precise forging process to create a stiff structure that supports sharper acceleration and more efficient engine operation. The gold finish provides a distinctive appearance while the chain’s lightweight construction helps reduce drivetrain load without compromising strength.
Features include strategically placed lightening holes that help remove mud and disperse heat, along with special pins drilled at both ends to reduce weight. The edge-cut inner plates minimize friction and promote smooth engagement with the sprocket. A Chromium Carbide surface coating on the pins increases hardness and helps reduce wear during demanding motocross use. The non-sealed design further minimizes friction for responsive drivetrain performance.
This ThreeD chain is supplied in a 520 size with 116 links and is identified by manufacturer and vendor part number 520MXR3D-116G. Verify the motorcycle’s required chain size, link count, sprocket configuration, and fitment before installation. It is designed for compatible 125cc to 500cc motocross applications and should be installed and maintained according to the motorcycle and chain manufacturer’s recommendations.
