Designed to meet the rigorous demands of racing, this piston utilizes advanced metallurgical processes and precision machining to ensure reliability and optimal power output.\n\n### Advanced Manufacturing and Material Quality\n\nVertex pistons are crafted from specialized Low-Ex (low expansion) aluminium alloys, charged with high concentrations of silicon to provide superior thermal stability. Each piston is manufactured using either gravity casting or hydraulic forging processes, followed by a sophisticated heat treatment cycle. This cycle uses automated equipment to refine the material structure, ensuring maximum strength and durability under extreme operating conditions.\n\n### Precision Engineering and Surface Coatings\n\nEvery piston is machined using high-tech CNC software and diamond tooling to achieve exact surface finishes tailored to the requirements of the engine. To enhance performance and longevity, these pistons feature a two-stage coating system:\n\n \n- Molybdenum Bisulphite Coating: A specialized black coating that assists in the piston break-in process and significantly reduces friction during cylinder operation.\n \n- Phosphate Coating: Applied using technology derived from Formula One engine development, this coating provides increased hardness and surface porosity. It improves the adhesion of the Molybdenum coating, effectively doubling its durability.\n\n### Key Features\n\n \n- High-performance single ring race design\n \n- 66.36mm diameter\n \n- Advanced Low-Ex aluminium alloy construction\n \n- Superior heat treatment for structural integrity\n \n- Precision CNC machined with diamond tooling\n \n- Molybdenum and Phosphate dual-coating system for reduced friction and extended life\n \n- Rigorous manual and automatic quality control inspections","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/kawasaki-kx-250-2005-2008-grade-b-6636mm-single-ring-race-piston","buyOneNow":null,"basketWithThis":null}},"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.
