Pistons are made using gravity cast or hydraulic forging processes, followed by heat treatment in an automatic HT implant with solubilization by quench in hot water. Machining is completed using CNC machines and diamond tools to achieve specific surface finishes. Each Vertex piston undergoes manual and automatic quality control. Vertex pistons are coated with a Molybdenum Bisulphite black coating to aid break-in and reduce friction. Vertex also offers a new Phosphate Coating with increased hardness and surface porosity for superior adhesion and durability of the Molybdenum Coating.

Manufactured using high-grade Low-Ex (low expansion) silicon-charged aluminium alloys, these pistons offer exceptional durability and thermal stability. Whether you are racing or maintaining your machine for top-tier performance, this piston provides the strength required for rigorous off-road conditions.\n\n### Advanced Engineering and Construction\n\nVertex utilizes a sophisticated gravity cast or hydraulic forging process to create the piston blank, which is further refined through an automated heat treatment process. This ensures a superior material structure designed to withstand high pressure and extreme heat. Precision CNC machining combined with high-tech diamond tooling ensures exact tolerances and optimal surface finishes for your specific cylinder requirements.\n\n### Key Features\n\n \n- High Performance Alloys: Constructed from Low-Ex aluminium with 12%, 18%, or 21% silicon content for minimal expansion and maximum longevity.\n \n- Dual Coating Technology: Features a Molybdenum Bisulphite black coating to reduce friction and assist with the initial break-in period.\n \n- Enhanced Durability: Incorporates a specialized Phosphate coating, inspired by Formula One developments, which increases surface hardness and significantly improves the adhesion and lifespan of the Molybdenum coating.\n \n- Quality Assured: Every piston undergoes a rigorous manual and automatic quality control inspection to ensure it meets the highest standards for manufacturing accuracy.\n \n- Single Ring Design: Optimized for reduced friction and improved engine response.\n\nBy integrating cutting-edge metallurgical processes and precision manufacturing, Vertex pistons provide an ideal solution for engine rebuilds where performance and consistent operation are the top priorities.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/ktm-sx-250-2003-2004-grade-c-6636mm-single-ring-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.
