Built in the popular 520 chain size, this non-sealed design reduces rotating mass and helps deliver direct power transfer from the engine to the rear wheel. The gold finish adds a distinctive appearance while providing a professional look suitable for performance-focused builds and replacement applications.\u003cbr\u003eThe 520ERT3 chain is supplied in a 120-link configuration with a rivet-style connection identified by the RB designation. Its non-sealed construction is intended for applications where low friction, efficient power delivery, and frequent maintenance are priorities. Without sealed rings, the chain allows for straightforward cleaning, lubrication, inspection, and adjustment, making it a practical choice for riders who regularly service their motorcycles or replace chains as part of a race-preparation routine.\u003cbr\u003eUse the D.I.D 520ERT3 Gold chain as a replacement for compatible motorcycle drivetrains that specify a 520 non-sealed chain. Always confirm the required chain size, link count, sprocket compatibility, and master-link installation method before installation. Proper alignment, tension, lubrication, and regular inspection are essential for maximizing chain life and maintaining reliable performance. The D.I.D brand is recognized for motorcycle chain engineering, making this part a suitable option for performance maintenance, track preparation, and off-road applications where drivetrain efficiency is important.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eBrand: D.I.D motorcycle chain engineered for performance-focused drivetrain applications\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePart Number: 520ERT3120RB\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eChain Size: 520 chain size for compatible motorcycle sprockets and drivetrains\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eChain Type: Non-sealed construction for low-friction operation and simplified service\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFinish: Gold-colored finish for a distinctive, professional appearance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eConfiguration: 120-link chain supplied with an RB rivet-style connection designation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eApplication: Suitable for compatible performance, track, race-preparation, and off-road motorcycle applications\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMaintenance: Supports regular cleaning, lubrication, inspection, and tension adjustment\u003c\/li\u003e\u003c\/ul\u003e","brand":"D.I.D","offers":[{"title":"Default Title","offer_id":44771484663850,"sku":"338592","price":154.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/2285\/8794\/files\/338527_1738094893_b7b01165-1b75-4b36-acfc-393095d12b79.jpg?v=1788225851","url":"https:\/\/atticusgoods.com\/products\/d-i-d-520ert3-gold-non-sealed-motorcycle-chain-120-link-part-520ert3120rb","provider":"Atticus Goods","version":"1.0","type":"link"}
