Engineered for precision and longevity, this piston is manufactured using advanced materials and cutting-edge production techniques to meet the demands of high-performance riding.\n\nVertex utilizes high-quality Low-Ex (low expansion) silicon-charged aluminium alloys to ensure structural integrity and optimal thermal management. Each piston is produced through either a gravity cast or hydraulic forging process, followed by a sophisticated heat treatment that refines the material structure for maximum strength.\n\n### Key Features\n\n \n- Advanced Alloy Composition: Constructed with silicon-charged aluminium alloys (12%, 18%, or 21% depending on the specific application) for reduced expansion and increased durability.\n \n- Precision Machining: CNC-machined using state-of-the-art software and diamond tools to achieve exacting surface finishes tailored for performance.\n \n- Dual Coating Technology: Features a specialised Molybdenum Bisulphite black coating to reduce friction during the critical break-in period. This is further enhanced by an all-over Phosphate Coating, which improves hardness and provides superior adhesion for the Molybdenum layer, effectively doubling its durability.\n \n- Rigorous Quality Control: Every unit undergoes both manual and automatic inspection processes to ensure that only the highest quality components reach your engine.\n \n- Twin Ring Design: Engineered to provide a consistent seal and maintain optimal compression throughout the life of the piston.\n\nWhether you are performing a routine rebuild or seeking to maintain factory-level performance, Vertex pistons offer the professional-grade reliability required for peak engine operation.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/honda-cr-250-1989-1994-grade-a-6634mm-twin-ring-replica","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/843995d9dc1f:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/843995d9dc1f: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.
