Manufactured using exotic Low-Ex silicon-charged aluminium alloys, this piston is designed to withstand the high-stress environments found in modern two-stroke engines. Whether you are performing a routine top-end rebuild or looking for a performance upgrade, this component provides an ideal solution for maintaining engine longevity and efficiency.\n\n### Advanced Manufacturing and Durability\n\nVertex utilizes a sophisticated heat treatment process in a fully automated environment to refine the material structure of each piston. This cutting-edge method ensures optimal tensile strength and thermal stability. The machining process incorporates state-of-the-art CNC technology and diamond tooling to achieve exact tolerances and specific surface finishes tailored to your engine requirements.\n\n### Surface Coatings for Enhanced Performance\n\nTo reduce internal friction and ensure a smoother break-in period, this piston features a specialized Molybdenum Bisulphite black coating. Complementing this is an advanced Phosphate coating, a technology derived from Formula One engine development. This phosphate layer increases surface hardness and provides superior adhesion for the Molybdenum coating, resulting in significantly extended durability compared to standard aftermarket pistons.\n\n### Key Features\n\n \n- Precision Engineering: Manufactured using Low-Ex silicon-charged alloys for minimal thermal expansion and maximum durability.\n \n- Twin Ring Design: Optimized for consistent compression and effective heat transfer.\n \n- Molybdenum Bisulphite Coating: Reduces friction during the break-in phase and throughout the piston life cycle.\n \n- Phosphate Surface Treatment: Increases wear resistance and improves coating adhesion for long-term engine protection.\n \n- Quality Assurance: Every piston undergoes rigorous manual and automatic quality control inspections to meet strict engineering standards.\n \n- Grade B Sizing: Features a 57.95mm diameter to ensure a perfect fit within the cylinder.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/ktm-sx-xc-w-150-2016-2023-exc-tpi-2020-grade-b-5795mm-twin-ring-replica-piston","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/189ba99c37aa:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/189ba99c37aa: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.
