By utilizing gravity casting technology with an aluminum alloy containing 18% silicon, these pistons offer superior durability and efficiency compared to standard components. This specific design ensures your engine maintains precise internal tolerances during operation.\n\nThe inclusion of high silicon content provides several distinct advantages for high-performance two-stroke applications:\n\n \n- Reduced Thermal Expansion: The high silicon content minimizes thermal expansion as the engine reaches operating temperature. This allows for tighter tolerances, resulting in improved power delivery and performance while reducing the risk of piston rattle or structural failure.\n \n- Enhanced Wear Resistance: The material composition provides excellent wear characteristics, significantly prolonging the service life of both the piston and the piston skirt.\n \n- Optimized Geometry: Because two-stroke engines operate with different cylinder pressures than four-strokes, this cast design is specifically tailored to maintain its intended geometry under load.\n\nDesigned for riders and mechanics who demand reliability and consistent output, this Vertex piston is a premium replacement choice for your engine rebuild. Whether you are performing routine maintenance or a full top-end overhaul, this component provides the strength and longevity required for demanding two-stroke operation.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/husqvarna-crwr-125-1988-1991-grade-c-5598mm","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/aa765dcf3e5a:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/aa765dcf3e5a: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.
