Crafted by Athena, a leading name in motorcycle spare parts for over four decades, this piston is engineered using advanced reverse extrusion and cutting-edge CNC machining. This meticulous process ensures dimensional tolerances of less than 0.01 mm, guaranteeing a perfect fit and optimal function.\n\n Constructed from a specialized high-performance aluminum alloy rich in silicon, Athena pistons offer the same dependability as Original Equipment (OE) pistons but with significantly improved resistance and superior performance. The precisely shaped piston profile promotes smooth airflow and efficient flame propagation for maximum power output.\n\n Select pistons feature a molybdenum disulfide coating applied via screen printing. This treatment further reduces friction, contributing to enhanced performance and extended durability. Every Athena piston is meticulously engineered in Italy and rigorously tested on dynamometers and tracks under extreme conditions to validate its performance and resilience.\n\n This piston kit includes high-quality piston rings designed to minimize friction with the cylinder, resulting in increased performance. The included rings are produced in Japan with wear-resistant coatings, such as PVD or chromium nitride, to boost durability and longevity. These rings are engineered to conform precisely to the cylinder liner, even under low tangential load.\n\n The Athena Piston Kit provides everything needed for installation: the piston, pin, circlips, and piston rings. All components are replaceable and interchangeable, offering convenience and long-term value.\n\n Please note that Athena products designed for increased displacement and power beyond standard road regulations are intended exclusively for competitive use. Athena disclaims all responsibility for any use of the product that contravenes national regulations.\n\n#### Key Technical Specifications:\n\n \n- Big End Pin Diameter: 18x10.5x44.5 mm\n \n- Bore Diameter: 96.96 mm\n \n- Compression Height: 24.10 mm\n \n- Compression Ratio: 12.5:1\n \n- Displacement: 450 cc\n \n- Net Weight: 0.32 Kg\n \n- Number Of Segments (Piston Rings): 2\n \n- Piston Pin Type: Standard\n \n- Piston Type: Forged","weightGrams":null,"fitments":[{"make":"YAMAHA","model":"WR 450F","cc":null,"notes":null,"years":"2016–2019"},{"make":"YAMAHA","model":"WRF 450","cc":null,"notes":null,"years":"2016–2019"},{"make":"YAMAHA","model":"YZ 450F","cc":null,"notes":null,"years":"2014–2019"},{"make":"YAMAHA","model":"YZ 450FX","cc":null,"notes":null,"years":"2016–2019"},{"make":"YAMAHA","model":"YZF 450","cc":null,"notes":null,"years":"2014–2019"},{"make":"YAMAHA","model":"YZF X 450","cc":null,"notes":null,"years":"2016–2019"}],"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-97mm-yamaha-wryz-450-14-18-athena-s5f09700003b","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/09aafde7054d:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/09aafde7054d: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.
