Engineered for precision and longevity, this component is designed to restore original performance levels while providing exceptional durability under high-stress conditions.\n\n### Advanced Material Technology\n\nVertex pistons are manufactured using specialized Low-Ex (low expansion) aluminium alloys, silicon-charged to ensure structural integrity. Each piston undergoes a sophisticated gravity casting or hydraulic forging process, refined by an automated heat treatment cycle. This combination of advanced metallurgy and thermal processing results in a component that offers superior strength and consistent performance.\n\n### Precision Engineering and Durability\n\nEach piston is machined using state-of-the-art CNC technology and diamond tooling to achieve precise surface finishes tailored to your engine requirements. To further enhance longevity and efficiency, these pistons feature a specialized Molybdenum Bisulphite black coating, which aids in the break-in process and significantly reduces internal cylinder friction.\n\n### Enhanced Phosphate Coating\n\nBenefiting from developments inspired by Formula One engineering, this piston incorporates an all-over Phosphate coating. This treatment offers a slight increase in surface hardness and optimized porosity, which ensures superior adhesion of the Molybdenum coating. This multi-layer approach doubles the durability of the piston coating for a longer service life.\n\n### Key Features\n\n- Manufactured from high-strength Low-Ex aluminium alloy\n\n- Precision CNC machined with diamond tooling for an exact fit\n\n- Molybdenum Bisulphite coating to reduce friction and assist break-in\n\n- Phosphate coating for improved durability and lubricant adhesion\n\n- Rigorous manual and automatic quality control testing\n\n- Single ring design optimized for race and replica applications\n\n- Size: 53.93mm Grade B","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/honda-cr-125-2000-2003-grade-b-5393mm-single-ring-replica-piston","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/64fff563cf21:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/64fff563cf21:1"}},"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.
