Vertex is a world leader in piston manufacturing, utilizing advanced materials and state of the art production techniques to ensure superior durability and function in high performance two stroke engines.\n\n### Advanced Manufacturing Technology\n\nEach piston is crafted from exotic Low-Ex silicon-charged aluminium alloys. Depending on the specific application, these alloys contain 12 percent, 18 percent, or 21 percent silicon to manage thermal expansion effectively. These components undergo either gravity casting or hydraulic forging processes, followed by a sophisticated heat treatment in an automated implant with hot water quenching to refine the material structure for maximum strength.\n\n### Precision Machining and Quality Control\n\nVertex utilizes the latest CNC machining and diamond tooling to ensure exact tolerances and specific surface finishes tailored to the requirements of the engine. Every piston undergoes rigorous manual and automatic quality control inspections to guarantee that only the highest quality components reach your engine.\n\n### Enhanced Coatings for Performance and Longevity\n\nTo ensure smooth operation and long term reliability, these pistons feature specialized surface treatments:\n\n \n- Molybdenum Bisulphite Coating: A high performance black coating that aids in the critical piston break in period while reducing friction during high RPM operation.\n \n- Phosphate Coating: Drawing from Formula One engine development, this coating provides a slight increase in surface hardness and introduces light surface porosity. This serves to improve the adhesion of the Molybdenum coating, effectively doubling its durability for extended service life.\n\n### Key Features\n\n \n- Grade D size: 53.95mm\n \n- Single ring design for reduced friction and improved seal\n \n- Replica profile for direct replacement compatibility\n \n- High silicon content aluminium alloy for thermal stability\n \n- Molybdenum and Phosphate coatings for friction reduction and wear resistance\n \n- Manufactured in Europe to the highest industry standards","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/honda-cr-125-2004-grade-d-5395mm-single-ring-replica-piston","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/b98c7e0ebdd2:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/b98c7e0ebdd2:1"}},"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.
