Vertex is a trusted name in high-end engine components, renowned for their precision engineering and commitment to quality.\n\n**Advanced Material Construction**\n\nEach piston is crafted from exotic Low-Ex (low expansion) silicon-charged aluminium alloys. The silicon content is precisely balanced at 12%, 18%, or 21% to suit specific engine applications. The blanks are created via gravity casting or hydraulic forging, followed by a sophisticated heat treatment process in an automatic implant with hot water quenching to refine the material structure and maximize strength.\n\n**Precision Machining and Quality Control**\n\nVertex utilizes state-of-the-art CNC machinery, advanced software, and diamond tooling to achieve exact specifications and superior surface finishes. Every piston undergoes rigorous manual and automatic quality control inspections to guarantee optimal performance consistency.\n\n**Enhanced Friction Reduction and Durability**\n\nTo ensure longevity and smooth operation, these pistons feature a specialized Molybdenum Bisulphite black coating. This coating assists during the break-in period and actively reduces friction during engine operation. Furthermore, Vertex incorporates a phosphate coating inspired by Formula One technology. This layer increases surface hardness and provides light porosity, which significantly improves the adhesion and durability of the Molybdenum coating.\n\n \n- Diameter: 57.96mm\n \n- Design: Single ring configuration\n \n- Grade: B\n \n- Material: Low-expansion silicon-charged aluminium alloy\n \n- Surface Treatment: Molybdenum Bisulphite and Phosphate coatings\n \n- Manufacturing: CNC machined with precision diamond tooling\n \n- Quality Assurance: Rigorous manual and automatic inspection process","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/yamaha-yz-144-2005-2018-grade-b-5796mm-single-ring-piston","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/7a1972f546ee:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/7a1972f546ee: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.
