This comprehensive set combines a high-performance forged piston with a meticulously engineered top-end gasket kit, designed to work in perfect harmony for optimal results.\n\nAthena pistons are manufactured using state-of-the-art CNC machines from a special high-performance aluminum alloy with a high silicon content. This ensures reliability comparable to Original Equipment (OE) pistons while offering superior resistance and performance. The smooth piston profile promotes regular airflow and optimal flame propagation. Some pistons feature a molybdenum disulfide coating on their skirts, applied via screen printing, to further reduce friction, boosting both performance and durability.\n\nThe included piston rings, sourced from Japan, are designed for reduced friction against the cylinder walls, contributing to higher performance. These rings feature wear-resistant coatings, such as PVD or chromium nitride, to extend their lifespan and maintain engine integrity.\n\nAthena's gasket kits are built upon decades of industry experience and continuous technological development. Developed by an in-house team of engineers and designers, these gaskets are produced following strict manufacturer parameters, with laser cutting ensuring precise quality. Athena utilizes advanced materials and surface treatments to ensure excellent sealing, even in critical areas, and employs material stress-relieving processes for enhanced reliability.\n\n#### Key Features:\n\n \n- Forged 4-stroke piston for enhanced performance and durability.\n \n- High-performance aluminum alloy with high silicon content.\n \n- Smooth piston profile for optimized airflow and flame propagation.\n \n- Optional molybdenum disulfide coating on piston skirts to reduce friction.\n \n- High-quality Japanese piston rings with wear-resistant coatings (PVD or chromium nitride).\n \n- Precision-engineered gasket kit for reliable sealing.\n \n- Developed and tested internally by Athena.\n\n#### Technical Specifications:\n\n \n- Big End Pin Diameter: 16x10x41.5 mm\n \n- Bore Diameter: 76.76 mm\n \n- Compression Height: 19.00 mm\n \n- Compression Ratio: 13.2:1\n \n- Displacement: 250 cc\n \n- Number of Rings: 2\n \n- Piston Pin Type: Standard\n \n- Piston Type: Forged","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/top-end-piston-gasket-kit-77mm-honda-crf-250-10-13-athena-p5f0768245001b-set-b","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/6bd080b80e51:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/6bd080b80e51:1"}},"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.
