Engineered for precision and durability, this piston is manufactured using advanced metallurgical processes to ensure optimal power delivery and long service life for your high-revving engine.\n\n### Advanced Manufacturing Technology\n\nVertex pistons are crafted from specialized Low-Ex (low expansion) aluminium alloys, charged with high silicon content (12%, 18%, or 21% depending on the specific application requirements). These pistons undergo a rigorous gravity casting or hydraulic forging process, followed by a sophisticated, automated heat treatment. This ensures a refined material structure capable of handling the extreme stresses found in high-performance racing environments.\n\n### Precision Machining and Durability\n\nEach piston is machined using state-of-the-art CNC technology and diamond-tipped tools to achieve exact tolerances and specific surface finishes. To further enhance performance, these pistons feature a dual-layer coating system:\n\n \n- Molybdenum Bisulphite Coating: A specialized black coating that reduces friction during the critical break-in period and throughout the piston's working life inside the cylinder.\n \n- Phosphate Coating: Drawing inspiration from Formula One engine technology, this layer provides a slight increase in surface hardness and creates a light surface porosity. This ensures superior adhesion of the Molybdenum coating, effectively doubling its durability.\n\n### Key Features\n\n \n- Grade A Precision: Engineered to meet exacting factory specifications for a perfect fit and consistent compression.\n \n- Single Ring Design: Optimized for reduced friction and improved throttle response.\n \n- Rigorous Quality Control: Every component undergoes both manual and automatic inspection to ensure the highest standards of manufacturing excellence.\n \n- Superior Longevity: Advanced alloy composition and state-of-the-art coatings provide exceptional resistance to wear and thermal fatigue.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/kawasaki-kx-125-1992-1993-grade-a-5395mm-single-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.
