Designed to withstand the rigors of both off-road environments and street riding, this high-carbon steel sprocket offers a significantly longer lifespan compared to standard alloy alternatives.\n\nBy choosing this premium steel construction, you protect your drivetrain components. A worn sprocket can prematurely damage your chain, but the high-strength build of the Supersprox racing sprocket ensures consistent performance and reduced maintenance over time.\n\n### Key Features and Technical Specifications\n\n \n- High-Carbon Steel Construction: Built with a core strength of 400MPa, ensuring the teeth resist bending or deformation even under high-torque applications.\n \n- Precision Machined: Manufactured using state-of-the-art laser cutting, CNC milling, and grinding processes to ensure absolute flatness and perfect roundness for a smooth power transfer.\n \n- Advanced Corrosion Protection: Features a dual-layer finish. A zinc carbonate barrier provides the initial foundation, while a Trivalent Chromium outer layer bonds to the surface. This creates a superior, durable black finish that resists corrosion far better than standard paint.\n \n- Engineered for Longevity: Designed to provide extended service life compared to alloy sprockets, making it the ideal choice for riders looking for a reliable, low-maintenance upgrade.\n \n- Superior Finish: Unlike competitors who rely on easily worn-off paint, the technical bonding process ensures the sprocket retains its professional, high-tech appearance throughout its life.\n\nWhether you are replacing a worn component or upgrading for increased reliability, the Supersprox steel rear sprocket provides the perfect balance of strength, precision, and corrosion resistance for your motorcycle.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/suzuki-rm-rmz-125-250-450-1985-2022-steel-rear-sprocket-49-tooth","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/b3970ed9081e:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/b3970ed9081e:1"}},"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.
