Designed for enhanced power and reliability, this kit is a direct replacement for specific applications, ensuring a precise fit and optimal function. Athena, a leader in motorcycle spare parts for over 40 years, utilizes advanced manufacturing techniques and high-quality materials to deliver exceptional engine components.\n\nThis piston is crafted from a special high-performance aluminum alloy with a high silicon content. This material ensures the same level of reliability as Original Equipment (OE) pistons while providing superior resistance and excellent performance gains. The piston's perfectly smooth profile promotes regular airflow and ideal flame propagation for improved combustion efficiency.\n\nSome Athena pistons feature a molybdenum disulfide coating on their skirts, applied using screen printing. This treatment further reduces friction, enhancing both performance and durability for extended engine life.\n\nAthena's commitment to quality is evident in their rigorous testing process. Each piston is engineered in Italy by the Athena R&D department and undergoes extensive testing on engine dynamometer benches and on-track validation in extreme conditions to ensure peak performance and unwavering reliability.\n\nThis piston kit includes the piston, pin, circlips, and piston rings. All components are designed to be replaceable and interchangeable, offering convenience and ease of maintenance.\n\n**Key Features:**\n\n \n- Piston Type: Forged\n \n- Bore Diameter: 79.97 mm\n \n- Compression Ratio: 13.5:1\n \n- Number Of Segments: 2\n \n- Piston Pin Type: Biconical\n \n- Big End Pin Diameter: 16x8x44 mm\n \n- Displacement: 250 cc\n \n- Weight: 0.22 Kg (Net)\n \n- Coating: Some skirts may feature a molybdenum disulfide coating to reduce friction.\n \n- Piston Rings: Produced in Japan with wear-resistant coatings (PVD or chromium nitride) for increased durability and retention.","weightGrams":null,"fitments":[{"make":"KTM","model":"250 EXC F CHAMPION","cc":null,"notes":null,"years":"2010"},{"make":"KTM","model":"250 EXC F FACTORY EDITION","cc":null,"notes":null,"years":"2011"},{"make":"KTM","model":"250 EXC-F","cc":null,"notes":null,"years":"2006–2013"},{"make":"KTM","model":"250 EXC-F SIX DAYS","cc":null,"notes":null,"years":"2009–2013"},{"make":"KTM","model":"250 SX-F","cc":null,"notes":null,"years":"2005–2012"},{"make":"KTM","model":"250 XC-F","cc":null,"notes":null,"years":"2006–2012"},{"make":"KTM","model":"250 XCF-W","cc":null,"notes":null,"years":"2006–2013"}],"collections":[{"name":"Engine","url":"https://www.2brosparts.com/api/agent/collection/GB/engine"},{"name":"Pistons & Kits","url":"https://www.2brosparts.com/api/agent/collection/GB/pistons-kits"}],"links":{"page":"https://www.2brosparts.com/products/piston-kit-b-80mm-ktm-exc-fsx-f-250-06-13-athena-s4f08000004b-for-290cc-big-bore","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/5538bbde48e8:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/5538bbde48e8:1"}},"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.
