Combining the rugged strength of steel with advanced manufacturing techniques, this sprocket is an ideal upgrade for high powered machines that face intense riding conditions.\n\nConstructed with a focus on longevity, these sprockets feature extra thick teeth. This design choice provides superior engagement with the drive chain, reducing wear and extending the lifespan of both your sprocket and chain set. Despite the heavy duty steel construction, the sprocket utilizes a lightened core design to reduce rotating mass by as much as 20 percent compared to standard steel replacements, ensuring your bike remains responsive.\n\n### Advanced Tri-Zinc Coating Technology\n\nSuperSprox utilizes a unique Tri-Zinc plating process to protect against the elements and maintain performance. This three stage finishing process ensures your sprocket stands up to the harshest racing environments:\n\n \n- Corrosion Resistance: The base layer consists of a silver and nickel mixture designed to prevent rust and oxidation.\n \n- Black Passivation: This step seals the micro pores in the steel surface, preventing abrasive debris and road grime from lodging in the material and causing premature wear.\n \n- Slick Top Coat: A final layer provides a smooth finish that resists dirt buildup and maintains a high quality aesthetic over time.\n\n### Key Features\n\n \n- CAD designed and precision laser cut for an exact fit and optimized geometry.\n \n- Steel construction offers superior longevity over aluminum alternatives.\n \n- Tri-Zinc plated finish provides industry leading corrosion protection and a sleek black aesthetic.\n \n- Extra thick tooth profile ensures better chain contact and component durability.\n \n- Lightened core design reduces rotating mass to improve handling and acceleration.\n \n- Engineered to retain stock pitch requirements for seamless integration.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/kawasaki-kxkxf-125250450500-1980-2022-black-50-tooth-rear-sprocket","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.
