Engineered for riders looking to increase displacement and power, this 57.95mm piston is manufactured using advanced aluminium alloys and cutting-edge production techniques to ensure durability and reliability under high-performance conditions.\n\n### Advanced Manufacturing and Material Quality\n\nVertex pistons are crafted from Low-Ex (low expansion) Silicon-charged alloys, utilizing gravity casting or hydraulic forging processes. The structural integrity of each piston is refined through a high-tech heat treatment process involving automatic solubilization and hot water quenching. Precision CNC machining and diamond tooling ensure exact tolerances and specific surface finishes tailored for high-output engine environments.\n\n### Enhanced Durability and Reduced Friction\n\nThis piston features a specialized Molybdenum Bisulphite black coating, which is essential for reducing friction during the break-in period and throughout the engine's operational life. To further improve longevity, Vertex incorporates an all-over Phosphate coating. This treatment provides a slight increase in surface hardness and a light porosity that promotes superior adhesion of the Molybdenum coating, effectively doubling its durability.\n\n### Key Features\n\n \n- Increased Displacement: Designed for 145cc big bore applications with a 57.95mm bore size.\n \n- Superior Alloy Construction: Utilizes high-silicon content alloys for thermal stability and low expansion.\n \n- Molybdenum Coating: Reduces friction and aids in smooth piston break-in.\n \n- Phosphate Coating: Enhances the adhesion and lifespan of the primary friction-reducing coating.\n \n- Strict Quality Control: Every unit undergoes rigorous manual and automated inspections to meet premium standards.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/ktm-sx-exc-125-2007-2017-big-bore-145cc-5795mm","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/8c3c9acc767b:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/8c3c9acc767b: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.
