Engineered for precision and longevity, this piston is manufactured using advanced metallurgical processes to ensure it meets the demands of high-performance riding.\n\nVertex utilizes high-quality Low-Ex (low expansion) silicon-charged aluminium alloys, chosen specifically for their durability and thermal stability. The production process involves sophisticated gravity casting or hydraulic forging, followed by a cutting-edge heat treatment that refines the material structure for superior strength.\n\n### Key Features and Engineering\n\n \n- Precision Machining: Every piston is crafted using state-of-the-art CNC machinery and diamond-tipped tooling to ensure exact surface finishes and tight tolerances.\n \n- Advanced Coatings: The piston features a Molybdenum Bisulphite black coating, which significantly aids in the break-in process and reduces internal friction.\n \n- Phosphate Treatment: Incorporating technology derived from Formula One engines, an all-over phosphate coating is applied. This creates a hard, porous surface that improves the adhesion and durability of the Molybdenum coating, effectively doubling its lifespan.\n \n- Quality Assurance: Each unit undergoes a rigorous inspection process, including both manual and automatic quality control checks, ensuring that only the highest standard of components reaches your engine.\n\nWhether you are performing a top-end rebuild or seeking a reliable replacement part, this Vertex piston offers the professional-grade quality required to maintain peak engine efficiency.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/suzuki-rm-250-2003-2012-grade-b-6634mm-twin-ring-piston","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/eddf60eee23e:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/eddf60eee23e: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.
