Engineered for durability and precision, this piston is designed to meet the rigorous demands of motocross and off-road riding, providing an ideal solution for top-end rebuilds and cylinder refurbishment.\n\n### Advanced Manufacturing Technology\n\nVertex pistons are crafted using exotic Low-Ex (low expansion) silicon-charged aluminium alloys. Depending on the specific application, these alloys are enriched with 12 percent, 18 percent, or 21 percent silicon to ensure structural integrity and heat resistance. The manufacturing process utilizes either gravity casting or hydraulic forging, followed by a state-of-the-art heat treatment in an automatic implant to refine the material structure for maximum strength.\n\n### Precision Machining and Durability\n\nEach piston is machined using the latest CNC technology and diamond-tipped tooling to achieve the exact surface finish required for optimal engine performance. To ensure long-lasting reliability, these pistons feature a specialized Molybdenum Bisulphite black coating. This treatment reduces friction during the critical break-in period and throughout the life of the piston.\n\n### Enhanced Phosphate Coating\n\nTaking inspiration from Formula One engine development, this piston incorporates an all-over Phosphate coating. This layer provides a slight increase in surface hardness and introduces light surface porosity. This design feature offers superior adhesion for the Molybdenum coating, effectively doubling the durability of the protective finish.\n\n### Key Features\n\n \n- Oversize specification at 67.95mm (+1.6mm).\n \n- Twin ring design for improved sealing and heat transfer.\n \n- Engineered from high-silicon content aluminium alloys.\n \n- Advanced heat treatment process for improved material structure.\n \n- Precision CNC machined with diamond tooling.\n \n- Molybdenum Bisulphite coating to reduce internal friction.\n \n- Phosphate coating for enhanced adhesion and coating longevity.\n \n- Strict manual and automatic quality control testing.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/kawasaki-kx-250-2002-2004-16mm-ovedrsize-6795mm-twin-ring-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.
