Built with advanced materials and manufacturing techniques, this piston offers excellent durability and consistent performance on the track or the trail.\n\n### Advanced Manufacturing and Material Quality\n\nVertex pistons are constructed using specialized Low-Ex (low expansion) aluminum alloys with varied silicon content tailored to the specific application. These pistons undergo a gravity cast or hydraulic forging process, followed by state-of-the-art heat treatment in automated implants. This precise solubilization and quenching process ensures a refined material structure that delivers superior strength and heat resistance.\n\n### Precision Engineering and Coatings\n\nEach piston is machined using high-end CNC equipment and diamond tooling, allowing for specific surface finishes that optimize performance. To further enhance longevity and efficiency, these pistons feature a multi-layer coating system:\n\n \n- Molybdenum Bisulphite Coating: A black friction-reducing layer that assists during the critical engine break-in period and minimizes drag during operation.\n \n- Phosphate Coating: Drawing inspiration from Formula One technology, this all-over surface treatment provides increased hardness and slight surface porosity. This allows for superior adhesion of the Molybdenum coating, effectively doubling its durability.\n\n### Key Features\n\n \n- Grade C sizing with a 67.46mm diameter.\n \n- Twin ring design for optimal sealing and compression.\n \n- High-tech heat-treated aluminum alloy for maximum structural integrity.\n \n- Advanced friction-reducing surface treatments for extended service life.\n \n- Rigorous manual and automatic quality control testing for consistent reliability.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/ktm-sx-gs-250-1990-1994-grade-c-6746mm-twin-ring-piston","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/a1af052b7636:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/a1af052b7636:1"}},"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.
