Engineered for riders seeking increased displacement and power, this 80mm piston features a 13.4:1 compression ratio, designed to deliver optimal combustion efficiency and improved torque throughout the powerband.\n\n### Advanced Manufacturing and Material Quality\n\nVertex utilizes specialized Low-Ex (low expansion) Silicon-charged aluminum alloys to ensure structural integrity under extreme heat and pressure. Depending on the specific application, these alloys contain 12%, 18%, or 21% silicon content to minimize expansion and maintain precise clearances. Each piston blank is created through either gravity casting or hydraulic forging, followed by a sophisticated, automated heat treatment process to refine the material structure for maximum durability.\n\n### Precision Engineering and Durability\n\nEvery piston is finished using state-of-the-art CNC machining and diamond tooling, ensuring surface finishes are optimized for the rigors of high-performance riding. To further enhance longevity and performance, Vertex incorporates a two-layer coating system:\n\n \n- Molybdenum Bisulphite Coating: A specialized black coating that aids in the break-in process and significantly reduces friction during operation.\n \n- Phosphate Coating: Inspired by Formula One technology, this coating provides increased surface hardness and light porosity. This allows for superior adhesion of the Molybdenum coating, effectively doubling its durability.\n\nRigorous manual and automatic quality control inspections are performed on every piston to ensure the highest standards of reliability and performance are met before leaving the factory.\n\n### Key Features\n\n \n- Increased displacement with 80mm bore diameter\n \n- High-performance 13.4:1 compression ratio\n \n- Low-Ex Silicon aluminum alloy construction for thermal stability\n \n- Advanced friction-reducing Molybdenum Bisulphite coating\n \n- Enhanced durability with phosphate coating technology\n \n- Precision CNC machined for exact tolerances","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/kawasaki-kxf-250-2017-2019-big-bore-80mm-1341","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/b58a5eb7c520:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/b58a5eb7c520:1"}},"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.
