Designed to withstand the rigors of off-road riding, this sprocket provides a high-strength alternative to lightweight alloy options that wear down quickly. Whether you are hitting the track or riding for pleasure, this sprocket ensures your drivetrain remains robust and consistent.\n\n### Advanced Manufacturing and Material Quality\n\nConstructed from high-carbon steel with a core strength of 400MPa, these sprockets are built to resist bending and deformation, even under the stress of high-power engines. Every unit undergoes a precision manufacturing process, including laser cutting, CNC milling, and surface grinding, to ensure perfect flatness and roundness for optimal power transfer.\n\n### Technical Corrosion Resistance\n\nUnlike standard sprockets that rely on paint, the Supersprox steel sprocket features a specialized dual-layer finish. The process begins with a zinc carbonate barrier to prevent rust, followed by a Trivalent Chromium layer. This technical bonding process provides superior corrosion protection while maintaining a sleek, professional black finish that will not flake or wear off after a few rides.\n\n### Key Features\n\n \n- 52 Tooth Configuration: Precision-cut for smooth chain engagement and efficient power delivery.\n \n- High-Carbon Steel: 400MPa core strength prevents tooth deformation under heavy load.\n \n- Precision Machined: Manufactured using CNC technology and surface grinding for maximum accuracy.\n \n- Advanced Surface Finish: Trivalent Chromium coating offers high-level corrosion resistance and long-lasting aesthetics.\n \n- Extended Lifespan: Designed to outlast traditional alloy sprockets, helping to preserve the life of your chain.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/suzuki-rm-rmz-125-250-450-1985-2022-steel-rear-sprocket-52-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.
