Athena engineers all components internally, ensuring perfect tuning between the piston and gaskets for superior results.\n\n The forged pistons are manufactured using state-of-the-art CNC machinery from a special aluminum alloy with a high silicon content. This provides excellent strength and durability comparable to Original Equipment (OE) pistons, while also offering enhanced resistance and improved performance. The smooth piston profile promotes consistent airflow and efficient flame propagation. Some pistons feature a molybdenum disulfide coating on the skirts to further reduce friction, boosting performance and longevity. The included piston rings, manufactured in Japan, feature wear-resistant coatings (PVD or chromium nitride) for reduced friction against the cylinder wall, leading to higher performance and extended durability.\n\n Athena's gasket kits are built upon over 40 years of industry experience, guaranteeing exceptional reliability. Developed by an in-house team of engineers and designers, and produced to strict manufacturer parameters, these gaskets ensure a perfect seal. Advanced laser cutting technology guarantees precise fitment, and Athena utilizes a wide range of raw materials, including surface treatments to address irregularities and material stress-relieving processes for improved sealing in critical areas.\n\n#### Key Features:\n\n \n- Forged 4-stroke piston for high performance and durability.\n \n- Top end gasket kit included for a complete engine rebuild.\n \n- Special high-performance aluminum alloy with high silicon content.\n \n- CNC machined for precision and consistent quality.\n \n- Smooth piston profile for optimal airflow and flame propagation.\n \n- Molybdenum disulfide coating on select piston skirts to reduce friction.\n \n- High-quality Japanese piston rings with wear-resistant coatings (PVD or chromium nitride).\n \n- Gaskets designed for maximum reliability and seal integrity.\n \n- Precise cutting quality achieved through advanced laser technology.\n\n#### Technical Specifications:\n\n \n- Big End Pin Diameter: 16x9x38.2 mm\n \n- Bore Diameter: 77.95 mm\n \n- Compression Height: 19.40 mm\n \n- Compression Ratio: 13.9:1\n \n- Displacement: 250 cc\n \n- Number Of Segments: 2\n \n- Piston Pin Type: Biconical\n \n- Piston Type: Forged","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/top-end-piston-gasket-kit-78mm-ktm-exc-f-250-14-16-athena-p5f0780074001a-set-a","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/b9afe148c3aa:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/b9afe148c3aa: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.
