Manufactured using advanced gravity casting techniques, this piston features an aluminum alloy with an 18 percent silicon content, ensuring optimal performance under demanding riding conditions.\n\nVertex pistons are designed to maintain structural integrity while providing precise clearance. By incorporating a high silicon content, these pistons effectively reduce thermal expansion, allowing for tighter tolerances compared to standard forged pistons. This specialized construction not only enhances engine power and performance but also minimizes the risk of rattling or component failure.\n\n### Key Features\n\n \n- Advanced Alloy Composition: Constructed with 18 percent silicon content for superior strength and reduced thermal expansion.\n \n- Precision Engineering: Allows for tighter tolerances, which results in better power delivery and overall engine responsiveness.\n \n- Enhanced Durability: Superior wear characteristics significantly prolong the life of the piston skirt.\n \n- Two-Stroke Optimized: Specifically designed to handle the unique demands of two-stroke engine cycles.\n \n- Twin Ring Design: Provides excellent ring seal and compression consistency for reliable performance.\n\nChoosing a Vertex gravity-cast piston ensures that your engine benefits from reduced friction and improved thermal stability, making it an ideal choice for maintenance and performance upgrades.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/husqvarna-crwr-250-1998-2013-grade-a-6634mm-twin-ring-piston","buyOneNow":null,"basketWithThis":null}},"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.
