Designed to meet the demands of competitive riding, this piston combines advanced metallurgy with precision manufacturing to deliver superior power, reliability, and engine longevity.\n\nVertex pistons are gravity cast from a high-quality aluminum alloy containing 18% silicon content. This specific composition provides critical advantages for two-stroke engines by reducing thermal expansion. Because the piston maintains its geometry more effectively as it reaches operating temperatures, it allows for tighter tolerances, resulting in improved compression, increased power output, and reduced mechanical noise.\n\n### Key Features\n\n \n- Race Evolution Design: Developed specifically for racing environments where performance and durability are paramount.\n \n- Advanced Alloy Composition: 18% silicon content reduces thermal expansion, allowing for tighter clearances and improved engine performance.\n \n- Exclusive Mo52 Coating: Features a specialized coating to reduce friction and improve break-in characteristics.\n \n- Improved Top Land: Strengthened design to withstand the stresses of high-RPM racing.\n \n- Nitrided Rings: Includes high-durability rings to ensure optimal sealing and extended service life.\n \n- Enhanced Wear Resistance: The high silicon content provides excellent wear characteristics, significantly prolonging the lifespan of the piston skirt and cylinder wall.\n\nBy choosing a Vertex Race Evolution Piston, you are investing in a component that balances the performance benefits of tight tolerances with the proven durability of gravity-cast aluminum construction. Ideal for riders looking to maintain peak performance during demanding race conditions.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/husqvarna-tc-65-2017-2023-grade-ef-4498mm-race-evolution","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/ccefcabbf0a1:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/ccefcabbf0a1:1"}},"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.
