Vertex utilizes advanced manufacturing processes to ensure every piston delivers optimal power and longevity, making it an ideal choice for maintenance and performance upgrades.\n\n### Advanced Materials and Manufacturing\n\nVertex pistons are crafted from exotic Low-Ex (low expansion) silicon-charged aluminium alloys. Depending on the specific application, these alloys contain 12%, 18%, or 21% silicon content to minimize thermal expansion and maintain consistent clearance. Each piston is produced using either gravity casting or hydraulic forging, then refined through a state-of-the-art automated heat treatment process to improve material structure and durability.\n\n### Precision Engineering and Coatings\n\nEvery Vertex piston is machined on high-precision CNC equipment using diamond tooling to achieve exact surface finishes. To enhance engine longevity and performance, these pistons feature a multi-layer coating system:\n\n- Molybdenum Bisulphite Coating: A specialized black coating applied to aid during the break-in process and significantly reduce internal friction.\n\n- Phosphate Coating: Borrowing technology from Formula One, the all-over phosphate coating provides a slight increase in surface hardness and creates a light porosity that ensures superior adhesion of the molybdenum coating, doubling its durability.\n\n### Key Features\n\n- Grade B specification with a 63.95mm diameter\n\n- Twin ring design for optimized compression and sealing\n\n- Rigorous manual and automatic quality control inspections\n\n- Low expansion alloy composition for consistent thermal performance\n\n- Advanced friction-reducing surface treatments","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/ktm-exc-200-1998-2016-grade-b-6395mm-twin-ring-piston","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/3e7914e4a6de:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/3e7914e4a6de: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.
