Designed and engineered in Italy, this piston kit utilizes advanced manufacturing techniques to deliver exceptional durability and power.\n\nAthena pistons are crafted from a special high-performance aluminum alloy with a high silicon content, ensuring they meet or exceed Original Equipment (OE) standards. Manufactured using cutting-edge CNC machining, these pistons boast dimensional tolerances of less than 0.01 mm for a precise fit and optimal operation.\n\nKey Features:\n\n \n- Forged Piston: Constructed from a high-performance aluminum alloy for superior strength and resistance.\n \n- Precision Machining: CNC machined to exacting standards for perfect fitment and performance.\n \n- Reduced Friction: Some piston skirts feature a molybdenum disulfide coating, applied by screen printing, to further reduce friction, enhance performance, and improve durability.\n \n- Advanced Ring Technology: Piston rings are produced in Japan with wear-resistant coatings (PVD or chromium nitride) for increased lifespan and durability. They ensure less friction with the cylinder, leading to higher performance.\n \n- Complete Kit: Includes the piston, pin, circlips, and piston rings, with all components being replaceable and interchangeable.\n \n- Engine Dynamometer Tested: Each piston undergoes rigorous testing on engine dynamometer benches and on track to validate performance in extreme conditions.\n\n**Technical Specifications:**\n\n \n- Bore Diameter: 76.97 mm\n \n- Compression Height: 19.90 mm\n \n- Compression Ratio: 13.5:1\n \n- Number Of Segments: 2\n \n- Piston Type: Forged\n \n- Piston Pin Type: Biconical","weightGrams":null,"fitments":[{"make":"KAWASAKI","model":"KX 250F","cc":null,"notes":null,"years":"2010–2016"}],"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-77mm-kawasaki-kx-250-11-14-athena-s5f07700001b","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/b1e25b9ca80d:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/b1e25b9ca80d: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.
