Designed for precision and durability, this +1.1mm oversize piston features a 67.45mm diameter, providing an effective solution for cylinder bores that have been bored out for a rebuild.\n\nVertex pistons are manufactured using exotic Low-Ex silicon-charged aluminium alloys, chosen for their specific thermal expansion properties. Whether produced via gravity casting or hydraulic forging, each piston undergoes a cutting-edge heat treatment process in an automatic implant with hot water quenching to refine the material structure and ensure long-term reliability.\n\n### Advanced Engineering and Coating Technology\n\nTo ensure peak performance and longevity, Vertex utilizes advanced CNC machining and diamond-tipped tooling to achieve the exact surface finish required for high-stress engine environments. Every unit is subjected to rigorous manual and automatic quality control inspections.\n\nEach piston is finished with a Molybdenum Bisulphite black coating, which assists in the initial break-in period and reduces friction within the cylinder walls. Furthermore, Vertex integrates a specialized Phosphate Coating, inspired by Formula One technology. This coating provides increased surface hardness and a light porosity that ensures superior adhesion of the Molybdenum finish, effectively doubling the durability of the protective layer.\n\n### Key Features\n\n \n- Precision Oversize: +1.1mm oversize (67.45mm) design for engine rebuilds.\n \n- Premium Material: Constructed from high-tech Low-Ex aluminium alloys with varying silicon content for optimal expansion control.\n \n- Advanced Surface Coatings: Molybdenum Bisulphite coating reduces friction and aids break-in.\n \n- Enhanced Durability: Phosphate coating provides superior hardness and improves the lifespan of the Molybdenum treatment.\n \n- High-Tech Manufacturing: CNC machined with diamond tools for exacting tolerances and professional-grade performance.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/kawasaki-kx-250-1992-1997-11mm-oversize-6745mm-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.
