{"product_id":"420-mru-drive-chain","title":"420 MRU Drive Chain","description":"MRU features RK’s proprietary Ultra Thin Seal, U-Rings, where the thickness of the seal is less than 50% of the most common O-ring seal. 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.\u003cbr\u003e\u003cbr\u003eFeatures:\u003cbr\u003e• Tensile Strength: 4,540 lbs\u003cbr\u003e• Max CC Rating: 150cc Street, 150cc Off-road\u003cbr\u003e• Max Horsepower: 25 HP\u003cbr\u003e• Weight: 1.74 lbs\u003cbr\u003e• Max Chain Width: 17.1mm\u003cbr\u003e• Master Link Included: Clip type","brand":"RK EXCEL","offers":[{"title":"MASTER LINK BL420MRU CLIP BLACK","offer_id":47505653596309,"sku":"691-1800BK","price":6.66,"currency_code":"USD","in_stock":true},{"title":"BL420MRU DRIVE CHAIN BLACK 420 X 120","offer_id":47505653629077,"sku":"691-1801BK","price":160.04,"currency_code":"USD","in_stock":true},{"title":"BL420MRU DRIVE CHAIN BLACK 420 X 130","offer_id":47505653661845,"sku":"691-1802BK","price":173.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0771\/8898\/9077\/files\/2655-6936f265aae80.png?v=1782747207","url":"https:\/\/shop.motomavericks.com\/products\/420-mru-drive-chain","provider":"MotoMavericks","version":"1.0","type":"link"}
