Designed for big bore applications, this kit provides a 284cc displacement with a 13.5:1 compression ratio, offering a significant upgrade for off-road enthusiasts.\n\nAthena pistons are manufactured using advanced reverse extrusion and cutting-edge CNC machining tools, ensuring dimensional tolerances of less than 0.01 mm. Constructed from a special high-performance aluminum alloy with a high silicon content, these pistons offer superior resistance and excellent performance while maintaining the reliability of original equipment.\n\nSome piston skirts feature a molybdenum disulfide coating applied by screen printing, which further reduces friction, enhancing both performance and durability. Each piston is rigorously tested on engine dynamometer benches and on track in extreme conditions to validate its performance and reliability.\n\nThis comprehensive kit includes the forged piston, piston pin, circlips, and piston rings. The piston rings, produced in Japan with wear-resistant coatings like PVD or chromium nitride, are designed for reduced friction and increased durability, adapting perfectly to the cylinder liner even at low tangential loads.\n\n**Key Features:**\n\n \n- Forged piston construction for superior strength and durability.\n \n- Special high-performance aluminum alloy with high silicon content.\n \n- Precision CNC machining for tight tolerances.\n \n- Molybdenum disulfide coating on select piston skirts to reduce friction.\n \n- Includes piston, pin, circlips, and piston rings.\n \n- High-quality piston rings with wear-resistant coatings for longevity.\n \n- Engineered and tested by Athena R&D for optimal performance.\n \n- Designed for Athena Big Bore Cylinder applications.\n\n**Technical Specifications:**\n\n \n- Big End Pin Diameter: 16x10x44.5 mm\n \n- Bore Diameter: 81.96 mm\n \n- Compression Height: 19.00 mm\n \n- Compression Ratio: 13.5:1\n \n- Displacement: 284 cc\n \n- Net Weight: 0.23 Kg\n \n- Number Of Segments (Rings): 2\n \n- Piston Pin Type: Standard\n \n- Piston Type: Forged","weightGrams":null,"fitments":[{"make":"HONDA","model":"CRF 230R","cc":null,"notes":null,"years":"2010–2013"},{"make":"HONDA","model":"CRF 250R","cc":null,"notes":null,"years":"2010–2017"},{"make":"HONDA","model":"CRF 250X","cc":null,"notes":null,"years":"2010–2011"}],"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-honda-crf-250-10-17-athena-s5f08200002b-280cc-big-bore-kit-b","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/c0536230d9e9:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/c0536230d9e9:1"}},"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.
