Designed for racing applications, this piston utilizes advanced metallurgical processes to meet the demands of high-output engines.\n\nVertex utilizes exotic Low-Ex (low expansion) silicon-charged aluminium alloys, with silicon content ranging from 12% to 21% depending on the specific application. These pistons are crafted using either gravity cast or hydraulic forging methods, followed by a sophisticated heat treatment process that includes solubilization and a hot water quench to refine the material structure for maximum durability.\n\nEvery piston is precision-machined using state-of-the-art CNC technology and diamond tooling to achieve exact surface finishes. To ensure longevity and performance, these pistons feature a specialized Molybdenum Bisulphite black coating, which reduces friction and assists during the initial break-in period. This is further enhanced by an advanced Phosphate Coating, which improves hardness and provides superior adhesion for the Molybdenum layer, effectively doubling the durability of the protective coating.\n\n### Key Features\n\n \n- High-Performance Alloy: Constructed from low-expansion silicon-charged aluminium for superior thermal stability.\n \n- Precision Engineering: Machined with high-tech CNC equipment and diamond tools for exact tolerances.\n \n- Advanced Coating Technology: Includes a Molybdenum Bisulphite coating for reduced friction and a phosphate base for enhanced durability.\n \n- Quality Assured: Undergoes rigorous manual and automatic quality control inspections to ensure industry-leading performance.\n \n- Optimized Dimensions: Grade B piston with a 53.94mm diameter.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/honda-rs-gp-125-1992-1994-grade-b-5394mm","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/8ac713441c32:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/8ac713441c32:1"}},"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.
