Crafted with precision and advanced engineering, this kit is engineered to meet the demands of high-performance riding.\n\nAthena pistons are manufactured using a specialized high-silicon aluminum alloy and cutting-edge CNC machining to achieve incredibly tight dimensional tolerances. This ensures exceptional reliability, comparable to Original Equipment (OE) pistons, while providing superior resistance and improved performance. The smooth piston profile promotes efficient fuel flow and optimal flame propagation.\n\nSome pistons feature a molybdenum disulfide coating applied via screen printing to the skirt. This treatment further reduces friction, contributing to enhanced performance and extended durability.\n\nEach Athena piston is meticulously engineered in Italy and rigorously tested on engine dynamometers and on track to validate performance under extreme conditions.\n\nThis piston kit includes the piston, pin, circlips, and piston rings. All components are designed for interchangeability.\n\n**Key Features:**\n\n \n- High-performance aluminum alloy with high silicon content.\n \n- Precision CNC machining for dimensional accuracy less than 0.01 mm.\n \n- Special molybdenum disulfide coating on some piston skirts to reduce friction.\n \n- Engineered and tested for extreme conditions.\n \n- Includes piston, pin, circlips, and piston rings.\n \n- Piston rings produced in Japan with wear-resistant coatings for increased durability.\n\n**Technical Specifications:**\n\n \n- Big End Pin Diameter: 15x10x45 mm\n \n- Bore Diameter: 57.94 mm\n \n- Displacement: 125 cc\n \n- Net Weight: 0.19 Kg\n \n- Number Of Segments: 1\n \n- Piston Head Type: Flat\n \n- Piston Pin Type: Biconical\n \n- Piston Type: Melted","weightGrams":null,"fitments":[{"make":"KAWASAKI","model":"KX 125","cc":null,"notes":null,"years":"2003–2007"}],"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-58mm-kawasaki-kx-125-03-07-athena-s4c05800002a-144cc-big-bore-kit-a","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/4369c40e4a39:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/4369c40e4a39:1"}},"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.
