Crafted from a special high-performance aluminum alloy with a high silicon content, these pistons offer superior reliability, enhanced resistance, and excellent performance compared to original equipment.\n\n Engineered with cutting-edge CNC machining, this piston ensures dimensional tolerances of less than 0.01 mm. The smooth profile promotes regular flow and perfect flame propagation. Some piston skirts feature a molybdenum disulfide coating applied by screen printing to further reduce friction, boosting performance and durability.\n\n Athena's commitment to quality is evident, with all pistons engineered in Italy and rigorously tested on dynamometer benches and tracks under extreme conditions. This piston kit is specifically designed for Athena Big Bore cylinder kits and includes high-performance piston rings manufactured in Japan with wear-resistant coatings. These rings minimize friction with the cylinder, leading to higher performance and increased durability.\n\n **Key Features:**\n\n \n- Forged racing piston with a 97.97 mm diameter.\n \n- Constructed from a special high-performance aluminum alloy with high silicon content.\n \n- Manufactured using advanced CNC machining for precise tolerances.\n \n- Features a smooth profile for optimal flow and flame propagation.\n \n- Some models include a molybdenum disulfide coating on the skirt for reduced friction.\n \n- Includes piston rings manufactured in Japan with wear-resistant coatings (PVD or chromium nitride).\n \n- Compression Ratio: 12.9:1\n \n- Kit includes: Piston, piston pin, circlips, and piston rings. All components are replaceable.\n\n All Athena products designed for increased displacement and power beyond road regulations are intended exclusively for competitive use. Athena is not responsible for any use of the product contrary to national regulations.","weightGrams":null,"fitments":[{"make":"HONDA","model":"CRF 450R","cc":null,"notes":null,"years":"2017–2021"},{"make":"HONDA","model":"CRF 450RX","cc":null,"notes":null,"years":"2017–2021"}],"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-98mm-honda-crf-450-17-22-athena-s4f09800011b-470cc-big-bore-kit-b","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/372fd7ade38a:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/372fd7ade38a: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.
