Trusted by professional racing teams, Vertex utilizes advanced manufacturing techniques to ensure optimal strength, durability, and engine efficiency. Each piston is precision-crafted to provide a perfect balance of weight and structural integrity.\n\n### Advanced Material Technology\n\nVertex pistons are constructed from specialized low-expansion silicon-charged aluminum alloys. This material choice is critical for maintaining structural stability under extreme thermal stress. The refinement process includes state-of-the-art heat treatment in automated implants, ensuring consistent material density and performance reliability throughout the entire component.\n\n### Precision Engineering and Surface Finishing\n\nUsing cutting-edge CNC machinery and diamond-tipped tooling, Vertex achieves a specific surface finish tailored for high-output environments. The piston features a specialized Molybdenum Bisulphite black coating, which significantly reduces friction during the critical break-in phase and throughout the engine operation cycle. Furthermore, the application of a phosphate coating enhances surface hardness and porosity, providing superior adhesion for the Molybdenum layer and effectively doubling the durability of the piston finish.\n\n### Key Features\n\n- 53.96mm Grade C flat top design\n\n- Features a.78mm ring configuration\n\n- Constructed from high-grade silicon-charged aluminum alloy\n\n- Advanced heat treatment for improved material structure\n\n- Molybdenum Bisulphite friction-reducing coating\n\n- Enhanced phosphate coating for increased durability and coating adhesion\n\n- Rigorous manual and automatic quality control testing\n\n- Engineered to reduce internal engine friction and improve wear resistance","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/honda-rs-125-2003-2009-grade-c-5396mm-flat-top-78mm-ring","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/f8c8904548d9:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/f8c8904548d9:1"}},"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.
