Manufactured by Athena.","descriptionMarkdown":"### Athena Forged Piston Kit B 77MM\n\nThis high-performance forged piston kit from Athena is designed for optimal power and reliability. Manufactured using advanced reverse extrusion and cutting-edge CNC machining, these pistons ensure exceptional dimensional accuracy, with tolerances less than 0.01 mm.\n\nCrafted from a specialized high-silicon aluminum alloy, Athena pistons offer superior resistance and performance while maintaining the reliability of original equipment. The piston's smooth profile promotes efficient airflow and perfect flame propagation. Some models feature a molybdenum disulfide coating on the piston skirts, applied via screen printing, to further reduce friction, enhancing both performance and durability.\n\nEngineered in Italy, each Athena piston undergoes rigorous testing on dynamometer benches and on the track to validate its performance under extreme conditions. The included piston rings, produced in Japan with wear-resistant coatings (PVD or chromium nitride), minimize friction with the cylinder, contributing to higher performance and extended durability. These rings are designed for perfect cylinder liner adaptation even at low tangential loads.\n\nThis comprehensive piston kit includes the piston, pin, circlips, and piston rings. All components are designed for easy replacement and interchangeability.\n\n**Key Features:**\n\n \n- Piston Type: Forged\n \n- Bore Diameter: 76.97 mm\n \n- Compression Height: 19.70 mm\n \n- Compression Ratio: 13.5:1\n \n- Displacement: 250 cc\n \n- Number Of Segments: 2\n \n- Piston Pin Type: Biconical\n \n- Big End Pin Diameter: 16x9x40.1 mm\n \n- Net Weight: 0.24 Kg\n \n- Includes piston, pin, circlips, and piston rings.\n \n- High-performance aluminum alloy with high silicon content.\n \n- Advanced CNC machining for precise tolerances.\n \n- Optional molybdenum disulfide coating on skirts for reduced friction.\n \n- Durable piston rings with wear-resistant coatings.\n \n- Engineered and tested for extreme conditions.","weightGrams":null,"fitments":[{"make":"KAWASAKI","model":"KX 250F","cc":null,"notes":null,"years":"2006–2010"}],"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-kawasaki-kx-250-07-10-athena-s5f07700005b","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/9ab95025c509:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/9ab95025c509:1"}},"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.
