Manufactured using a gravity-cast process from a premium aluminum alloy containing 18% silicon, this piston offers the ideal balance of durability and performance for demanding riding conditions.\n\nVertex pistons are designed to maintain tighter tolerances than forged alternatives. The high silicon content significantly decreases thermal expansion, ensuring that the piston maintains its geometry even when operating at high temperatures. This precision fit results in improved engine power, reduced mechanical noise, and enhanced resistance to breakage.\n\n**Key Features:**\n\n \n- Advanced Alloy Composition: Gravity-cast aluminum with 18% silicon content for superior strength and heat resistance.\n \n- Reduced Thermal Expansion: Allows for tighter clearances, leading to better compression and increased overall engine performance.\n \n- Enhanced Wear Resistance: The unique material properties extend the lifespan of the piston by minimizing skirt wear during high-RPM operation.\n \n- Single Ring Design: Optimized for reduced friction and improved throttle response.\n \n- Grade A Specification: Precision-engineered to exact dimensions for a reliable, high-quality replacement.\n\nChoosing a Vertex piston ensures that your two-stroke engine receives a component built for longevity and consistent power delivery, making it an excellent choice for maintaining the performance of your machine.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/husqvarna-crwrsm-125-1997-2013-grade-a-5394mm-single-ring-piston","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/94fff1adb24d:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/94fff1adb24d: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.
