Engineered specifically for high-performance two-stroke applications, this piston is designed to meet the rigorous demands of motocross and enduro racing.\n\nVertex utilizes a specialized gravity casting process to create these pistons from an aluminum alloy containing 18% silicon. This specific material composition is optimized for two-stroke engines, which operate under different pressure characteristics compared to four-stroke counterparts. By integrating a high silicon content, Vertex provides a superior alternative to standard forged components.\n\n### Key Features\n\n \n- Reduced Thermal Expansion: The high silicon content minimizes thermal expansion, allowing the piston to maintain its intended geometry even at high operating temperatures. This enables tighter running tolerances, resulting in improved power delivery and performance.\n \n- Enhanced Durability: Designed for longevity, the piston features excellent wear characteristics. The material composition significantly decreases wear on the piston skirt, extending the service life of your top-end.\n \n- Precision Engineering: Engineered to reduce the risk of rattling or structural failure, ensuring a smooth and consistent performance across the entire powerband.\n \n- Optimized for Two-Strokes: Specifically formulated for the lower cylinder pressures found in two-stroke engines to provide the best balance of strength and lightweight efficiency.\n\nWhether you are performing a routine rebuild or a full engine refresh, choosing a Vertex piston ensures that your machine benefits from decades of racing development and high-quality metallurgical standards.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/husqvarna-crwr-125-1995-1996-grade-ef-5597mm","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.
