Specifically designed for two-stroke applications, these pistons offer superior durability and efficiency through advanced material science and manufacturing precision.\n\nVertex utilizes a gravity-cast process to create these pistons from a high-quality aluminum alloy featuring an 18% silicon content. This specific composition is ideal for the lower cylinder pressures found in two-stroke engines, providing optimal strength while maintaining long-term performance.\n\n### Key Features\n\n \n- Reduced Thermal Expansion: The high silicon content minimizes thermal expansion, allowing the piston to maintain its geometry at operating temperatures. This enables tighter tolerances for improved power and performance.\n \n- Enhanced Wear Resistance: The silicon-enriched alloy provides excellent wear characteristics, significantly extending the service life of the piston and reducing friction on the piston skirt.\n \n- Precision Engineering: Designed to minimize rattling and prevent structural fatigue, these pistons offer a consistent and reliable power delivery throughout the rpm range.\n \n- Two-Stroke Optimized: Specifically developed for the unique demands of two-stroke engines, ensuring the ideal balance of weight, heat dissipation, and structural integrity.\n\nUpgrade your engine with a Vertex piston to experience the benefits of reduced mechanical noise, improved piston life, and consistent power output on the track or the trail.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/husqvarna-crwr-125-1988-1991-grade-a-5596mm","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.
