Engineered for precision and reliability, this replacement component is designed to meet the rigorous demands of two-stroke engines. By utilizing advanced manufacturing processes, Vertex ensures a high-quality product that helps restore your engine to its original factory specifications.\n\n### Advanced Materials and Manufacturing\n\nVertex pistons are manufactured using exotic Low-Ex (low expansion) silicon-charged aluminium alloys. This specific material composition is selected to handle high thermal loads while maintaining structural integrity. The pistons are crafted through either gravity casting or hydraulic forging, followed by a sophisticated heat treatment process in an automatic implant to refine the material structure for maximum durability.\n\n### Key Features\n\n \n- Precision Engineering: Machined using state-of-the-art CNC technology and diamond tooling for exact tolerances and superior surface finishes.\n \n- Molybdenum Coating: Features a specialized Molybdenum Bisulphite black coating that assists during the break-in process and reduces friction during cylinder operation.\n \n- Phosphate Coating Technology: Incorporates a phosphate coating that provides a slight hardness increase and improved surface porosity. This ensures superior adhesion of the Molybdenum coating, effectively doubling its durability.\n \n- Quality Assurance: Every piston undergoes a rigorous manual and automatic quality control process to ensure it meets the highest industry standards.\n \n- Twin Ring Design: Engineered for optimal sealing and compression, supporting consistent performance throughout the service life of the engine.\n\n### Reliable Performance\n\nDrawing on developments derived from Formula One technology, Vertex provides a piston solution that minimizes friction and enhances the longevity of your engine components. Whether you are performing a routine top-end rebuild or addressing engine wear, this Vertex replica piston offers the reliability and technical excellence required for demanding riding conditions.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/honda-cr-125-1992-1999-grade-c-5395mm-twin-ring-replica-piston","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/529fa07b79c9:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/529fa07b79c9:1"}},"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.
