Manufactured by industry leaders in high-performance engine components, this piston is designed to deliver superior durability and reliability under demanding riding conditions.\n\nVertex pistons are crafted using specialized Low-Ex (low expansion) aluminum alloys with varied silicon content, ensuring exceptional thermal stability. Using advanced gravity casting and hydraulic forging processes, the structural integrity of the material is further optimized through a sophisticated, high-tech heat treatment cycle.\n\n### Advanced Engineering and Design\n\nEvery Vertex piston is machined to exact tolerances using state-of-the-art CNC technology and diamond-tipped tooling. This manufacturing precision allows for specific surface finishes that are optimized for high-performance use.\n\n \n- Molybdenum Bisulphite Coating: A specialized black coating is applied to reduce friction during the break-in process and improve overall performance inside the cylinder.\n \n- Enhanced Phosphate Coating: Incorporating developments from Formula One, this piston features an all-over phosphate coating. This provides a slight increase in surface hardness and creates a light porosity that improves the adhesion of the Molybdenum coating, significantly extending its durability.\n \n- Quality Assured: Each piston undergoes rigorous manual and automated quality control inspections to ensure it meets the highest industry standards.\n \n- Twin Ring Design: Engineered to provide an optimal seal and improved heat transfer for consistent power delivery.\n\nWhether you are performing a routine rebuild or a performance upgrade, this Vertex piston offers the build quality and technological advancements required to maintain peak engine efficiency.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/yamaha-yz-250-1996-1998-grade-c-6796mm-twin-ring-piston","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/df31243c41a3:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/df31243c41a3:1"}},"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.
