Manufactured using cutting-edge CNC machining, it ensures precise dimensional tolerances for optimal engine function. The piston is crafted from a special aluminum alloy with a high silicon content, offering the reliability of original equipment (OE) pistons with enhanced durability and performance.\n\n The smooth piston profile promotes regular airflow and perfect flame propagation. Some piston skirts feature a molybdenum disulfide coating, applied via screen printing, to further reduce friction, boosting performance and longevity. Athena's commitment to quality means this piston meets or exceeds OE production standards, validated through rigorous engine dynamometer and track testing.\n\n Included piston rings are designed for reduced friction against the cylinder, contributing to higher performance. These rings are produced in Japan and feature wear-resistant coatings like PVD or chromium nitride for increased durability. The rings are designed to adapt perfectly to the cylinder liner, even under low tangential load.\n\n This comprehensive kit includes the piston, pin, circlips, and piston rings. All components are replaceable and interchangeable for convenience.\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- Precise CNC machining with dimensional tolerances of less than 0.01 mm.\n \n- Molybdenum disulfide coating on some piston skirts to reduce friction.\n \n- High-quality piston rings made in Japan with wear-resistant coatings.\n \n- Designed for excellent reliability and enhanced durability.\n \n- Engineered and tested in Italy for extreme conditions.\n \n- Includes piston, pin, circlips, and piston rings.\n\n **Technical Specifications:**\n\n \n- Bore Diameter: 76.76 mm\n \n- Compression Height: 19.10 mm\n \n- Compression Ratio: 13.5:1\n \n- Displacement: 250 cc\n \n- Number Of Segments: 2\n \n- Piston Type: Forged\n \n- Big End Pin Diameter: 16x10x41.5 mm\n \n- Piston Pin Type: Standard\n \n- Net Weight: 0.17 Kg","weightGrams":null,"fitments":[{"make":"HONDA","model":"CRF 250R","cc":null,"notes":null,"years":"2010–2016"}],"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-77mm-honda-crf-250-14-15-athena-s5f07680002b","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/48b9f5a4ef99:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/48b9f5a4ef99:1"}},"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.
