Crafted using advanced reverse extrusion and cutting-edge CNC machining, these pistons ensure exceptional dimensional accuracy. They are constructed from a specialized high-performance aluminum alloy with a high silicon content, providing OE-level reliability alongside enhanced resistance and superior performance.\n\n The piston's design features a perfectly smooth profile for optimal flow and efficient flame propagation. Select piston skirts are treated with a molybdenum disulfide coating, applied via screen printing, to further reduce friction, thereby increasing performance and longevity. Athena's commitment to quality is evident, with pistons engineered in Italy and rigorously tested on dynamometer benches and tracks under extreme conditions to validate their performance and reliability.\n\n This piston kit includes the piston, pin, circlips, and piston rings. The included piston rings are designed for reduced friction against the cylinder wall, contributing to higher performance. These rings are manufactured in Japan with wear-resistant coatings (PVD or chromium nitride) to boost durability and longevity, ensuring a perfect seal against the cylinder liner even at low tangential loads. All components in the kit are replaceable and interchangeable for convenience.\n\n **Key Features:**\n\n \n- Forged piston construction for superior strength and performance.\n \n- High-performance aluminum alloy with high silicon content.\n \n- Precision CNC machining ensures dimensional tolerances of less than 0.01 mm.\n \n- Smooth piston profile for optimized gas flow and combustion.\n \n- Molybdenum disulfide coating on select skirts reduces friction for improved performance and durability.\n \n- High-quality piston rings manufactured in Japan with advanced wear-resistant coatings.\n \n- Kit includes piston, pin, circlips, and piston rings.\n \n- All components are replaceable and interchangeable.\n\n **Technical Specifications:**\n\n \n- Bore Diameter: 76.75 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 (Piston Rings): 2\n \n- Piston Pin Type: Standard\n \n- Big End Pin Diameter: 16x10x41.5 mm\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-a-77mm-honda-crf-250-14-15-athena-s5f07680002a","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/7087293aa3f4:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/7087293aa3f4:1"}},"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.
