Manufactured using advanced low expansion silicon-charged aluminium alloys, these pistons are built to withstand the rigours of demanding engine environments while maintaining structural integrity.\n\n### Advanced Manufacturing and Quality Control\n\nVertex utilises state-of-the-art gravity casting and hydraulic forging processes, refined through precise heat treatment cycles in automated HT implants. Each piston is machined on high-end CNC equipment with diamond tooling to ensure exact surface finishes tailored to specific engine requirements. Every unit undergoes rigorous manual and automatic quality control inspections to meet professional-grade standards.\n\n### Superior Coating Technology\n\nThis piston features a dual-layer coating system designed to optimise performance and longevity:\n\n \n- Molybdenum Bisulphite Coating: A specialized black finish that assists in the break-in process and reduces friction during cylinder operation.\n \n- Phosphate Coating: Inspired by Formula One engine technology, this all-over coating increases surface hardness and provides light surface porosity. This enhances the adhesion of the Molybdenum coating, effectively doubling its durability.\n\n### Key Features\n\n \n- High-quality twin ring design for optimal compression sealing.\n \n- Precision engineered 66.34mm diameter.\n \n- Constructed from high-tech, low-expansion aluminium alloy.\n \n- Advanced friction-reducing coatings for extended engine life.\n \n- Developed for consistent performance under thermal stress.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/honda-cr-250-1995-1996-grade-a-6634mm-twin-ring-replica","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/2a7d5c03f792:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/2a7d5c03f792:1"}},"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.
