Engineered by Athena, a leader in motorcycle spare parts for over 40 years, this piston kit is designed for high-performance applications. Each piston is forged using a special high-performance aluminum alloy with a high silicon content, ensuring both reliability and enhanced durability.\n\nUtilizing cutting-edge CNC machining tools, Athena guarantees dimensional tolerances of less than 0.01 mm for precise fitment. This piston features a perfectly smooth profile for optimal air flow and flame propagation. Some pistons include a molybdenum disulfide coating on the skirts, applied via screen printing, to further reduce friction and boost performance and longevity.\n\nThe piston rings in this kit are produced in Japan and feature wear-resistant coatings (PVD or chromium nitride) to increase durability and lifespan. These rings are designed to perfectly adapt to the cylinder liner even under low tangential load, minimizing friction and maximizing performance.\n\nThis comprehensive kit includes the piston, piston pin, circlips, and piston rings. All components are replaceable and interchangeable, providing flexibility for maintenance.\n\n**Key Features:**\n\n \n- Forged piston for superior strength and performance.\n \n- High-performance aluminum alloy with high silicon content.\n \n- Precision CNC machining for tight tolerances.\n \n- Smooth profile for improved flow and combustion.\n \n- Optional molybdenum disulfide coating on skirts for reduced friction.\n \n- High-quality piston rings made in Japan with wear-resistant coatings.\n \n- Complete kit includes piston, pin, circlips, and rings.\n \n- Designed for Athena Big Bore cylinder kits.\n\n**Technical Specifications:**\n\n \n- Big End Pin Diameter: 16x9x40 mm\n \n- Bore Diameter: 81.96 mm\n \n- Compression Ratio: 13.5:1\n \n- Displacement: 250 cc\n \n- Net Weight: 0.22 Kg\n \n- Number of Segments: 2\n \n- Piston Pin Type: Biconical\n \n- Piston Type: Forged","weightGrams":null,"fitments":[{"make":"HUSQVARNA","model":"FC 250","cc":null,"notes":null,"years":"2014–2021"},{"make":"HUSQVARNA","model":"FE 250","cc":null,"notes":null,"years":"2014–2019"},{"make":"KTM","model":"250 EXC-F","cc":null,"notes":null,"years":"2014–2019"},{"make":"KTM","model":"250 SX-F","cc":null,"notes":null,"years":"2013–2021"},{"make":"KTM","model":"250 XC-F","cc":null,"notes":null,"years":"2016–2021"}],"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-82mm-ktmhusky-250-13-22-athena-s4f08200005b-276cc-big-bore-kit-b","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/c5ca242260c7:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/c5ca242260c7:1"}},"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.
