Engineered to meet the demands of high-performance riding, this piston is designed to provide optimal compression and long-lasting durability.\n\n### Advanced Manufacturing and Material Quality\n\nVertex pistons are crafted using specialized Low-Ex (low expansion) silicon-charged aluminium alloys. Depending on the specific application, these pistons utilize either a gravity cast or hydraulic forging process. The structural integrity is further refined through a state-of-the-art automated heat treatment process, ensuring the piston can withstand intense engine conditions.\n\n### Precision Engineering\n\nEach piston is machined using high-precision CNC technology and advanced diamond tooling to achieve exact surface finishes tailored to your engine requirements. Every unit undergoes a rigorous manual and automatic quality control inspection to ensure it meets the highest standards of manufacturing excellence.\n\n### Advanced Coating Technology\n\nTo reduce internal friction and assist during the critical break-in period, this piston features a Molybdenum Bisulphite black coating. Furthermore, it incorporates an advanced phosphate coating, inspired by Formula One engineering. This additional layer increases surface hardness and provides superior adhesion for the Molybdenum coating, resulting in significantly enhanced durability.\n\n### Key Features\n\n \n- Precision Diameter: 66.35mm Grade A sizing.\n \n- Twin Ring Design: Engineered for optimal sealing and performance.\n \n- High-Tech Alloy: Utilizes low expansion silicon-charged aluminium for consistent geometry under heat.\n \n- Reduced Friction: Molybdenum Bisulphite coating minimizes internal engine resistance.\n \n- Extended Coating Durability: Phosphate base layer provides increased hardness and superior coating longevity.\n \n- Quality Assured: Subjected to thorough automated and manual testing protocols.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/kawasaki-kx-250-1992-1997-grade-a-6635mm-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.
