Engineered for superior power and durability, this kit is designed for riders seeking an edge in off-road competition. Athena, a leader in motorcycle parts for over four decades, utilizes advanced manufacturing techniques to deliver exceptional quality and performance.\n\n This piston kit is crafted from a special high-performance aluminum alloy with a high silicon content. This material choice ensures reliability comparable to original equipment while offering increased resistance and enhanced performance. The precision CNC machining guarantees dimensional tolerances of less than 0.01 mm, resulting in a perfectly smooth profile for optimized airflow and flame propagation.\n\n Some piston skirts feature a molybdenum disulfide coating applied via screen printing. This treatment further reduces friction, contributing to improved performance and extended durability. Athena's commitment to quality means each piston is engineered in Italy and rigorously tested on engine dynamometer benches and on the track to validate performance under extreme conditions.\n\n The included piston rings are produced in Japan with wear-resistant coatings (PVD or chromium nitride) to maximize retention and durability. These rings are designed to adapt perfectly to the cylinder liner, even at low tangential loads, ensuring less friction and higher performance.\n\n This comprehensive kit includes the piston, pin, circlips, and piston rings, all of which are replaceable and interchangeable.\n\n **Key Features:**\n\n \n- Forged racing piston for high performance and durability.\n \n- Made from a special high-performance aluminum alloy with high silicon content.\n \n- Precision CNC machined for tight tolerances (less than 0.01 mm).\n \n- Optimized profile for regular airflow and perfect flame propagation.\n \n- Optional molybdenum disulfide coating on some skirts to reduce friction.\n \n- High-quality piston rings produced in Japan with wear-resistant coatings.\n \n- Complete kit includes piston, pin, circlips, and piston rings.\n \n- Engineered and tested by Athena R&D for extreme conditions.\n \n- Compression Ratio: 12.9:1\n\n _Please note: Products designed for increased displacement and power beyond road regulations are intended exclusively for competitive use. Athena disclaims responsibility for any use 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-a-98mm-honda-crf-450-17-22-athena-s4f09800011a-470cc-big-bore-kit-a","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/92e8dec38ae7:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/92e8dec38ae7:1"}},"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.
