Manufactured using advanced metallurgical techniques, this piston is designed to meet the rigorous demands of racing environments, ensuring optimal power delivery and reliability.\n\n### Advanced Manufacturing and Material Quality\n\nVertex pistons are crafted from high-grade Low-Ex (low expansion) silicon-charged aluminium alloys. Through a sophisticated gravity casting or hydraulic forging process, the structural integrity of the piston is refined via a cutting-edge heat treatment process. This ensures the component remains stable under extreme thermal stress.\n\n### Precision Engineering and Durability\n\nEvery piston is machined on state of the art CNC equipment using precision diamond tooling to achieve exact surface finishes tailored for high-performance applications. To enhance longevity and efficiency, these pistons feature a specialized Molybdenum Bisulphite black coating, which assists during the break-in period and significantly reduces internal friction.\n\n### Phosphate Coating Technology\n\nDrawing inspiration from Formula One engine developments, these pistons include an all-over phosphate coating. This treatment provides a slight increase in hardness and a light surface porosity, which improves the adhesion of the Molybdenum coating. This combination ensures maximum coating durability throughout the life of the piston.\n\n### Key Features\n\n \n- High-performance single ring design optimized for racing\n \n- Crafted from exotic, low-expansion silicon aluminium alloys\n \n- Advanced heat treatment process for superior material structure\n \n- CNC machined for exact tolerances and finish\n \n- Molybdenum Bisulphite coating to reduce friction during break-in\n \n- Enhanced phosphate coating for improved adhesion and wear resistance\n \n- Rigorous manual and automatic quality control testing","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/kawasaki-kx-250-2005-2008-grade-c-6637mm-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.
