Designed for compatible Kawasaki and Suzuki motorcycles, this 51-tooth black sprocket helps reduce rotating mass while providing dependable performance in demanding riding conditions. Part number 1120-520-51GPBK identifies this specific Renthal Twinring configuration.\u003cbr\u003eThe outer steel ring is manufactured with the minimum amount of material needed for strength and durability. During assembly, it is expanded with controlled heat and fitted over the aluminum inner ring. This interference fit, combined with the wave-pattern design, creates a permanent bond intended to remain secure throughout the service life of the chainwheel. Flat socket-head screws further reinforce the sprocket during side impacts while reducing the chance of contact with the chain guide.\u003cbr\u003eSelf-cleaning mud grooves between the teeth help prevent dirt buildup, reduce chain and sprocket wear, and maintain consistent chain engagement. Compared with a standard all-aluminum sprocket, the Renthal Twinring is engineered to last up to three times longer, while remaining considerably lighter than an all-steel rear sprocket. The black finish and precision construction make it a practical upgrade for riders seeking durability, weight savings, and reliable drivetrain performance.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003e7075-T6 aluminum inner ring provides high strength with reduced weight\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eElectroless nickel-coated steel outer ring is engineered for long-lasting durability\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePermanent interference-fit construction combines the inner and outer rings securely\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eWave-pattern design reinforces the bond between the aluminum and steel rings\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFlat socket-head screws add strength during side impacts and help prevent chain-guide contact\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSelf-cleaning mud grooves reduce dirt buildup, chainwheel wear, and weight\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDesigned to last up to three times longer than a standard all-aluminum sprocket\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eLighter than an all-steel rear sprocket\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003e51-tooth black rear sprocket for compatible Kawasaki and Suzuki applications\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eBrand: Renthal\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePart Number: 1120-520-51GPBK\u003c\/li\u003e\u003c\/ul\u003e\r\n\u003cp\u003eShips from Parts Unlimited.\u003c\/p\u003e","brand":"Renthal","offers":[{"title":"Default Title","offer_id":60116993769758,"sku":"1120-520-51GPBK","price":152.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1091\/7884\/7518\/files\/184298.png?v=1791096800","url":"https:\/\/shoplepier.com\/products\/renthal-twinring-rear-sprocket-51-tooth-black-kawasaki-suzuki-1120-520-51gpbk","provider":"LEPIER POWERSPORTS","version":"1.0","type":"link"}
