Engineered for reliability and power, this high-quality cast piston is specifically designed to meet the rigorous demands of two-stroke engines. By utilizing an advanced aluminum alloy with an 18% silicon content, Vertex provides a component that balances durability with precision engineering.\n\n### Advanced Silicon Alloy Construction\n\nThe core advantage of this piston lies in its gravity cast construction. The high silicon content offers several performance-enhancing benefits that ensure your engine runs smoother and lasts longer:\n\n- Reduced Thermal Expansion: Lower thermal expansion allows the piston to maintain its geometry at operating temperatures. This enables tighter running tolerances, resulting in improved power delivery and performance compared to forged alternatives.\n\n- Enhanced Durability: The silicon composition significantly improves wear resistance, specifically reducing friction on the piston skirt to extend the overall service life of the component.\n\n- Superior Stability: By minimizing expansion, the piston is less susceptible to breaking or rattling, providing peace of mind during high-intensity riding.\n\n### Key Features\n\n- Grade C 66.36mm diameter\n\n- Twin ring design for optimal sealing and compression\n\n- Gravity cast aluminum alloy construction\n\n- Designed for improved wear characteristics and reduced friction\n\n- Precision engineered for consistent performance","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/husqvarna-crwr-250-1998-2013-grade-c-6636mm-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.
