Engineered for precision and reliability, this 63.95mm piston is manufactured to exceed original equipment standards, providing a perfect balance of strength and lightweight performance.\n\nVertex utilizes exotic Low-Ex silicon-charged aluminium alloys, ranging from 12% to 21% silicon content, to ensure minimal thermal expansion and maximum durability under high-stress conditions. Each piston blank is crafted through advanced gravity casting or hydraulic forging, followed by a state-of-the-art heat treatment process that refines the material structure for superior resilience.\n\n### Advanced Engineering and Coating Technology\n\nTo ensure peak performance and reduced engine wear, Vertex incorporates cutting-edge finishing techniques. Using precision CNC machining and diamond tooling, these pistons achieve exact surface finishes tailored for optimal operation. Every unit undergoes rigorous manual and automatic quality control inspections to ensure absolute consistency.\n\nThese pistons feature a dual-layer coating system designed to handle the demands of high-performance engines:\n\n \n- Molybdenum Bisulphite Coating: A specialized black finish that significantly reduces friction during the critical break-in period and throughout regular operation.\n \n- Phosphate Coating: Inspired by Formula One engine technology, this layer provides a slight increase in surface hardness and improves oil retention. This porosity allows the Molybdenum coating to adhere more effectively, doubling the durability and lifespan of the surface treatment.\n\nChoose Vertex for your engine rebuild to benefit from race-proven technology and professional-grade materials designed to keep your machine running at its best.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/yamaha-banshee-350-atv-1987-2006-grade-a-6395mm","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/8c015cae26ab:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/8c015cae26ab: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.
