Designed with precision, this piston provides an ideal replacement solution for maintaining optimal power and reliability.\n\n**Advanced Material Composition**\n\nEach piston is crafted from exotic Low-Ex (low expansion) aluminium alloys, precision-charged with high percentages of silicon to ensure superior thermal stability and structural integrity. Through a combination of gravity casting or hydraulic forging and a sophisticated automated heat treatment process, these pistons achieve a refined material structure designed for longevity under stress.\n\n**Precision Engineering and Coatings**\n\nMachined using state-of-the-art CNC technology and diamond tooling, every piston meets exact specifications for surface finish. To enhance performance during the critical break-in period and throughout its lifespan, the piston features a Molybdenum Bisulphite black coating to reduce internal friction.\n\n**Durability Enhancements**\n\nVertex has integrated a phosphate coating across the piston surface. Inspired by Formula One technology, this layer provides a slight increase in surface hardness and optimized porosity. This ensures superior adhesion of the Molybdenum coating, effectively doubling its durability for consistent performance.\n\n### Key Features\n\n \n- Grade D: Precision sized at 53.98mm for exact clearance requirements.\n \n- Replica Design: Specifically engineered as a high-quality replacement to match original performance characteristics.\n \n- Advanced Alloy: Silicon-charged aluminium alloy for reduced expansion and increased strength.\n \n- Enhanced Lubrication: Molybdenum Bisulphite coating reduces friction and assists during engine break-in.\n \n- Durable Finish: Phosphate coating improves coating adhesion and wear resistance.\n \n- Quality Assured: Undergoes rigorous manual and automatic quality control inspections.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/kawasaki-kx-125-2003-2008-grade-d-5398mm-single-ring-replica-piston","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/d62a65e6c532:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/d62a65e6c532:1"}},"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.
