Manufactured using advanced Low-Ex silicon aluminum alloys, this piston provides exceptional structural integrity and thermal resistance. Vertex utilizes both gravity casting and hydraulic forging processes to ensure precision, followed by a sophisticated heat treatment cycle to refine the material structure for maximum durability.\n\nEvery piston is finished using precision CNC machining and high-tech diamond tooling, ensuring exact tolerances and optimal surface finishes. To enhance longevity and performance, these pistons feature a specialized Molybdenum Bisulphite black coating designed to assist in the break-in process while significantly reducing internal friction.\n\nFurthermore, these components include an advanced phosphate coating. Inspired by Formula One engine technology, this layer provides a slight increase in surface hardness and introduces light surface porosity. This design offers superior adhesion for the Molybdenum coating, resulting in a more durable finish that stands up to intense engine cycles.\n\n### Key Features\n\n \n- High Performance Alloy: Constructed from Low-Ex (low expansion) silicon-charged aluminum for enhanced reliability under stress.\n \n- Precision Engineering: Machined with state-of-the-art CNC technology and diamond tooling for perfect surface characteristics.\n \n- Advanced Coating Technology: Molybdenum Bisulphite coating reduces friction and facilitates a smoother engine break-in.\n \n- Enhanced Durability: Phosphate-coated surface improves coating adhesion, effectively doubling the lifespan of the protective finish.\n \n- Strict Quality Control: Each piston undergoes rigorous manual and automated inspections to ensure consistent quality and performance.\n \n- Application Focused: Single ring design specifically optimized for high-output engine configurations.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/suzuki-rm-250-1999-grade-a-6634mm-single-ring-piston","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/413827ad6a56:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/413827ad6a56:1"}},"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.
