This allows RK to design a sealed chain with the weight of a non-sealed chain. MRU will feature 4 times longer chain life than comparable non-sealed 420 chains and will require less chain adjustments compared to non-sealed 420 chains. MRU is available in RK’s black scale finish with black inner and black outer side plates with gold pins and gold rollers. \u003cbr\u003e \u003cbr\u003e \u003cul\u003e\n\u003cli\u003eTensile strength: 4,540 lbs\u003c\/li\u003e \u003cli\u003eMax CC rating: 150cc Street\u003c\/li\u003e \u003cli\u003eMax horsepower: 35 HP\u003c\/li\u003e \u003cli\u003eWeight: 1.74 lbs\u003c\/li\u003e \u003cli\u003eMax chain width: 17.1mm\u003c\/li\u003e \u003cli\u003eMaster link included: clip type\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RK EXCEL","offers":[{"title":"Default Title","offer_id":48130881618075,"sku":"RK BL420MRU-120","price":213.29,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0669\/9742\/0187\/files\/423323.jpg?v=1784085226","url":"https:\/\/grmotorcycle.com\/products\/rk-excel-420mru-120l-bk-rk-chain-bl420mru-120","provider":"GR Motorcycle","version":"1.0","type":"link"}
