RK rates the 520 Max O at 8500 lb (37.8 kN) tensile strength and lists it for street engines to 800 cc and off-road engines to 650 cc, far beyond what an e-moto drivetrain asks of it.\u003c\/p\u003e\n\u003cp\u003eChain size 520, 120 links, carbon alloy steel, gold finish, O-ring seal type, master link in rivet or clip form as supplied.

Cut the chain to the length your sprockets need and fit the master link with the closed end of the clip facing the direction of travel.\u003c\/p\u003e","brand":"RK","offers":[{"title":"Default Title","offer_id":67874412036325,"sku":"520MAXO-120-GG","price":118.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0511\/3964\/1496\/files\/rk-520-max-o-drive-chain-gold-120-links-1.png?v=1792846455","url":"https:\/\/gritshift.com\/products\/rk-520-max-o-drive-chain-gold-120-links","provider":"GritShift","version":"1.0","type":"link"}
