Engineered by Athena, a leader in motorcycle spare parts for over 40 years, this kit is designed for direct replacement of original equipment (OE) pistons and is also compatible with Athena cylinders.\n\nCrafted using advanced CNC machining tools, Athena pistons achieve exceptional dimensional accuracy, maintaining tolerances within 0.01 mm. They are constructed from a specialized high-performance aluminum alloy rich in silicon, offering the same dependability as OE pistons while delivering superior resistance and performance. The meticulously smooth piston profile promotes optimized airflow and efficient flame propagation for maximum power output.\n\nSome Athena piston skirts feature a molybdenum disulfide coating applied through screen printing. This treatment further reduces friction, leading to enhanced performance and extended durability of the piston.\n\nAthena's commitment to quality is evident in their rigorous testing process. Each piston is developed in Italy by the Athena R&D department and subjected to extensive testing on engine dynamometers under varying stress loads, followed by on-track validation in extreme conditions. This ensures that Athena pistons meet or exceed OE production standards for performance and reliability.\n\nThis piston kit includes all necessary components: the piston, pin, circlips, and piston rings. These parts are designed to be replaceable and interchangeable, providing convenience for maintenance.\n\n#### Key Technical Features:\n\n \n- Bore Diameter: 53.94 mm\n \n- Piston Type: Melted\n \n- Piston Head Type: Flat\n \n- Piston Pin Type: Biconical\n \n- Number Of Segments (Rings): 1\n \n- Compression Ratio: 14.8:1\n \n- Displacement: 125 cc\n \n- Big End Pin Diameter: 15x10x45 mm\n \n- Net Weight: 0.17 Kg\n\n**Please note:** Products designed for increased displacement and power beyond standard road regulations are intended exclusively for competitive use. Athena is not responsible for any use of the product contrary to national regulations. Warranty claims for competitive sports use or high-performance applications may be limited unless a clear manufacturing defect is present.","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-54mm-kawasaki-kx-125-03-07-athena-s4c05400010a-std-bore-kit-a","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/22406bb87b2c:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/22406bb87b2c: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.
