Designed to outperform lightweight alloy alternatives, this high-performance steel sprocket is built to withstand the rigors of off-road riding while maintaining exceptional durability for street use.\n\nUnlike standard aftermarket options, this sprocket is manufactured using high carbon steel with a core strength of 400MPa. This robust construction ensures the teeth remain resistant to bending or deformation, even when subjected to the high torque of powerful engines. By choosing a durable steel sprocket, you also protect your chain investment, as worn alloy sprockets are known to accelerate chain wear and shorten component life.\n\n### Key Features\n\n \n- Precision Engineering: Every sprocket undergoes an extensive manufacturing process including laser cutting, CNC machining, and surface grinding to ensure perfect flatness and roundness.\n \n- Superior Corrosion Protection: The signature black finish is achieved through a technical process that forms a zinc carbonate barrier, finished with a Trivalent Chromium layer. This is not paint; it is a chemically bonded coating that prevents corrosion and maintains a technical look over time.\n \n- High Carbon Steel Construction: Built for maximum strength, the 400MPa core ensures the sprocket teeth maintain their integrity under heavy load.\n \n- Long-Lasting Performance: Designed to offer a significantly longer service life compared to traditional aluminum sprockets, making it the ideal choice for riders who want to spend more time on the track or trail and less time on maintenance.\n\nWhether you are riding off-road or on the street, the Supersprox steel rear sprocket provides a reliable, high-quality solution that keeps your motorcycle running smoothly while offering excellent value for money.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/suzuki-rm-rmz-125-250-450-1985-2022-steel-rear-sprocket-51-tooth","buyOneNow":null,"basketWithThis":null}},"market":{"country":"GB","countryName":"United Kingdom","locale":"en-gb","currency":"GBP","exchangeRateFromGbp":1,"pricesIncludeUkVat":true,"checkoutTax":null,"delivery":[{"name":"Standard","description":"Orders £15.00–£59.99 · 2–4 business days","carrier":null,"estimatedDays":"2–4 business days","price":{"amount":4.99,"formatted":"£4.99"},"free":false,"minimumOrder":{"amount":0,"formatted":"£0.00","gbp":0},"weightGrams":null},{"name":"Standard","description":"Orders £60.00 and up · 2–4 business days","carrier":null,"estimatedDays":"2–4 business days","price":{"amount":0,"formatted":"£0.00"},"free":true,"minimumOrder":{"amount":60,"formatted":"£60.00","gbp":60},"weightGrams":null}],"storeUrl":"https://www.2brosparts.com"},"navigate":{"start":"https://www.2brosparts.com/api/agent","search":"https://www.2brosparts.com/api/agent/search/GB/{words+joined+with+plus}"},"howToBuy":{"summary":"Build a basket for the shopper and give them one checkout link.
