Designed for optimal performance, this 66.36mm Grade C piston is manufactured using advanced aluminium alloys and cutting-edge production techniques to ensure a perfect fit and long service life.\n\n### Advanced Engineering and Materials\n\nVertex pistons are crafted using exotic Low-Ex (low expansion) silicon-charged aluminium alloys. Depending on the specific application, these pistons contain 12, 18, or 21 percent silicon to minimize thermal expansion and maintain strict clearances under extreme operating temperatures. The blank parts are created through either gravity casting or hydraulic forging, followed by a sophisticated heat treatment process in an automatic HT implant to refine the material structure.\n\n### Key Features\n\n- Precision Machining: Every piston is finished on state-of-the-art CNC machinery using diamond-tipped tools to achieve the exact surface finish required for superior performance.\n\n- Enhanced Durability: Features an all-over Phosphate coating, inspired by Formula One engine technology. This provides a slight increase in hardness and creates a light surface porosity for superior adhesion.\n\n- Reduced Friction: Finished with a specialized Molybdenum Bisulphite black coating, which aids in the initial break-in period and significantly reduces friction during operation.\n\n- Double-Layer Coating Protection: The combination of Phosphate and Molybdenum coatings effectively doubles the durability of the piston surface compared to standard finishes.\n\n- Quality Assured: Each Vertex piston undergoes rigorous manual and automatic quality control inspections to guarantee the highest manufacturing standards.\n\n### Technical Specifications\n\n- Type: Single Ring Piston\n\n- Diameter: 66.36mm\n\n- Grade: C\n\n- Brand: Vertex","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/suzuki-rm-250-1999-grade-c-6636mm-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.
