Engineered for precision and reliability, this twin ring replica piston is designed to meet the rigorous demands of high-performance engines, ensuring optimal compression and efficient power delivery.\n\nVertex utilizes exotic Low-Ex silicon-charged aluminium alloys to construct each piston. Depending on the application requirements, these alloys contain 12%, 18%, or 21% silicon to provide the ideal balance of durability and thermal stability. The blanks are produced through advanced gravity casting or hydraulic forging processes, followed by a state of the art heat treatment that refines the material structure for superior strength.\n\nPrecision is at the heart of the Vertex manufacturing process. Every piston is machined using high-tech CNC equipment and diamond tools to achieve exact tolerances and specific surface finishes. To further enhance performance and break-in reliability, the piston features a Molybdenum Bisulphite coating, which reduces friction within the cylinder. This is complemented by an advanced Phosphate coating, which increases surface hardness and improves the adhesion and durability of the Molybdenum finish.\n\n### Key Features\n\n \n- Precision Engineering: Manufactured using high-tech CNC machining and diamond tooling for exact specifications.\n \n- Advanced Alloy Construction: Crafted from Low-Ex silicon-charged aluminium alloys for excellent thermal expansion control.\n \n- Durable Coatings: Features a Molybdenum Bisulphite friction-reducing coating paired with a Phosphate base for extended durability.\n \n- Twin Ring Design: Designed for consistent compression and effective ring-to-cylinder sealing.\n \n- Quality Assured: Undergoes rigorous manual and automatic quality control checks to ensure consistent high-quality output.\n \n- Oversize Specification: Designed at 67.45mm (+1.1mm) to assist with cylinder refurbishment and engine rebuilding.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/honda-cr-250-2002-2004-11mm-oversize-6745mm-twin-ring-replica","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/f1d37f61ed44:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/f1d37f61ed44:1"}},"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.
