Engineered to meet exacting standards, this piston is designed for riders seeking reliability and high-level performance during engine rebuilds. Precision-manufactured to provide a perfect fit for bored-out cylinders, this component ensures your engine maintains optimal compression and power delivery.\n\n### Advanced Manufacturing and Material Quality\n\nVertex pistons are crafted from high-grade Low-Ex (low expansion) silicon-charged aluminium alloys. The manufacturing process utilizes either gravity casting or hydraulic forging, followed by a sophisticated heat-treatment cycle in an automated implant to refine the material structure. This ensures superior strength and thermal stability under the rigorous conditions of high-performance riding.\n\n### Precision Engineering and Durability\n\nEvery piston is machined on state-of-the-art CNC equipment using diamond tooling to achieve exact surface finishes tailored to the application. To further enhance longevity, these pistons feature a specialized Molybdenum Bisulphite black coating, which assists in the initial break-in period and significantly reduces friction during operation.\n\n### Key Features\n\n \n- Precision Oversize: Engineered to 54.45mm (+0.50mm) specifications for precision cylinder restoration.\n \n- Advanced Coating Technology: Enhanced with a Molybdenum Bisulphite coating for reduced friction and improved break-in.\n \n- Phosphate Coating Integration: Features a phosphate surface treatment that provides superior adhesion for the molybdenum layer, doubling the durability of the protective coating.\n \n- Rigorous Quality Control: Every component undergoes strict manual and automatic inspection processes to ensure peak performance and reliability.\n \n- Heat-Treated Alloy: Constructed from exotic, low-expansion aluminium alloys to ensure structural integrity and consistent engine performance.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/kawasaki-kx-125-1998-050mm-oversize-5445mm-single-ring-replica-piston","buyOneNow":null,"basketWithThis":null}},"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.
