Manufactured using advanced metallurgical processes, this piston is designed to withstand the rigorous demands of high-output powerplants, ensuring long-lasting durability and consistent performance.\n\n### Advanced Materials and Engineering\n\nVertex pistons are crafted from high-grade Low-Ex (low expansion) aluminium alloys, featuring silicon concentrations tailored specifically to the application. Through a sophisticated gravity casting or hydraulic forging process, the structural integrity of the metal is refined via a precision heat treatment cycle in an automated implant, ensuring the piston maintains its shape and strength under extreme thermal stress.\n\n### Precision Machining and Quality Control\n\nEach piston is finished using state-of-the-art CNC technology and diamond-tipped tooling to achieve precise surface tolerances. Every unit undergoes a comprehensive manual and automatic quality control process to guarantee that the final product meets the highest industry standards for precision and longevity.\n\n### Engineered for Reduced Friction\n\nTo optimize internal performance, Vertex utilizes a dual-coating strategy:\n\n- Molybdenum Bisulphite Coating: A specialized black finish applied to the piston surface to facilitate a smooth break-in period and minimize friction against the cylinder wall.\n\n- Phosphate Coating: Borrowing technology from Formula One engines, this all-over coating increases surface hardness and provides light porosity. This significantly improves the adhesion of the Molybdenum coating, resulting in twice the coating durability compared to standard applications.\n\n### Key Features\n\n- Grade C sizing with a 51.97mm diameter.\n\n- Advanced Low-Ex aluminium alloy construction for thermal stability.\n\n- High-tech heat treatment process for refined material structure.\n\n- CNC machined to exact specifications for optimal fitment.\n\n- Advanced Phosphate and Molybdenum Bisulphite coatings to reduce friction and improve wear resistance.\n\n- Rigorous quality control testing ensures consistent quality in every unit.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/ktm-sx-105-2004-2017-grade-c-5197mm","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/1db0431a626b:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/1db0431a626b: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.
