Manufactured using cutting-edge CNC machining, these pistons achieve dimensional tolerances of less than 0.01 mm. Constructed from a special high-performance aluminum alloy with a high silicon content, they offer enhanced resistance and excellent performance while maintaining OE-level reliability.\n\nThe piston's 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. Athena engineers ensure advanced technical solutions and quality standards that meet or exceed OE production.\n\nEach piston is rigorously tested on engine dynamometer benches and on the track to validate performance in extreme conditions. The included piston rings, produced in Japan with wear-resistant coatings (PVD or chromium nitride), minimize friction with the cylinder, leading to higher performance and increased durability. The rings adapt perfectly to the cylinder liner even at low tangential load.\n\nThis complete piston kit includes the piston, pin, circlips, and piston rings. All components are replaceable and interchangeable.\n\n**Key Features:**\n\n \n- Piston Type: Forged\n \n- Bore Diameter: 95.96 mm\n \n- Compression Ratio: 12.5:1\n \n- Number Of Segments: 2\n \n- Piston Pin Type: Biconical\n \n- Big End Pin Diameter: 19x10x45 mm\n \n- Displacement: 450 cc\n \n- Net Weight: 0.36 Kg\n \n- Piston Rings: Wear-resistant coatings (PVD or chromium nitride)\n \n- Kit Contents: Piston, pin, circlips, and piston rings","weightGrams":null,"fitments":[{"make":"HONDA","model":"CRF 450R","cc":null,"notes":null,"years":"2009–2016"},{"make":"KAWASAKI","model":"KX 450F","cc":null,"notes":null,"years":"2009–2018"},{"make":"SUZUKI","model":"RM-Z 450","cc":null,"notes":null,"years":"2008–2019"}],"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-96mm-kawasaki-kx-250-09-18-athena-s4f09600017a-std-bore","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/4790ed6a1673:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/4790ed6a1673:1"}},"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.
