Designed as a superior alternative to alloy sprockets, this steel sprocket provides the longevity required for both street and off-road applications without compromising on strength or precision.\n\nConstructed from high carbon steel with a core strength of 400MPa, this sprocket is built to withstand high-torque environments without bending or deforming. By replacing worn sprockets with this high-quality steel component, you help preserve your chain life, as a worn sprocket is a primary cause of premature chain failure.\n\n### Key Features\n\n \n- Precision Engineering: Every sprocket undergoes an extensive manufacturing process, including laser cutting, CNC milling, and surface grinding, to ensure perfect flatness and roundness for smooth power delivery.\n \n- Superior Durability: Offers significantly longer service life compared to standard alloy sprockets, capable of covering high mileage on the street when paired with a quality chain.\n \n- Advanced Corrosion Resistance: Unlike competitors who use standard paint that wears away, this sprocket features a dual-layer treatment. A zinc carbonate base provides structural protection, followed by a Trivalent Chromium layer that creates a durable, high-tech black finish that resists rust and wear.\n \n- High Carbon Steel Construction: High-tensile material ensures the teeth maintain their integrity under the stress of powerful engines.\n \n- Versatile Application: Ideal for riders who prioritize reliability and maintenance intervals over the weight savings of aluminum parts.\n\nWhether you are replacing a worn drivetrain or looking to upgrade to a more reliable setup, the Supersprox Steel Rear Sprocket provides the technical performance and resilience needed for demanding riding conditions.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/suzuki-rm-rmz-125-250-450-1985-2022-steel-rear-sprocket-42-tooth","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/6dcb088ae170:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/6dcb088ae170:1"}},"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.
