Manufactured using advanced metallurgical processes and high-quality aluminium alloys, this 48.47mm piston provides an ideal balance of lightweight construction and structural durability.\n\n### Advanced Manufacturing and Material Quality\n\nVertex utilizes proprietary Low-Ex silicon-charged aluminium alloys, which are processed through precision gravity casting or hydraulic forging. This ensures a refined material structure that is further enhanced by cutting-edge, automated heat treatment. Every piston is machined on state-of-the-art CNC equipment using diamond tooling to achieve precise surface finishes tailored for high-output engine applications.\n\n### Enhanced Coatings for Superior Performance\n\nTo improve longevity and reduce internal friction, this piston features a dual-layer coating system:\n\n \n- Molybdenum Bisulphite Coating: A specialized black finish that assists in the piston break-in process and minimizes friction during cylinder operation.\n \n- Phosphate Coating: Drawing from Formula One engine technology, this all-over treatment provides a slight increase in surface hardness and improves the adhesion of the Molybdenum coating, resulting in significantly extended durability.\n\n### Key Features\n\n \n- Grade D sizing (48.47mm) for precise engine tolerances.\n \n- Single ring design optimized for racing applications.\n \n- Manufactured with high-silicon content alloys to prevent thermal expansion issues.\n \n- Rigorous manual and automatic quality control inspections for guaranteed consistency.\n \n- Engineered for reduced friction and increased service life.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/kawasaki-kx-85-2001-2022-grade-d-4847mm-single-ring-race-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.
