Engineered specifically for demanding engine environments, this piston is gravity cast from a premium aluminum alloy containing 18 percent silicon. This high silicon content provides essential advantages for two-stroke applications where precision and reliability are paramount.\n\n### Key Features\n\n \n- Reduced Thermal Expansion: The high silicon formula minimizes thermal expansion, allowing the piston to maintain its geometry as it reaches operating temperature. This enables tighter running tolerances for improved power delivery.\n \n- Enhanced Durability: The specialized alloy composition improves wear characteristics, significantly prolonging the lifespan of both the piston and the skirt.\n \n- Optimized Performance: By reducing the likelihood of rattling or breakage, this piston ensures a smoother engine operation and more consistent performance throughout the rev range.\n \n- Precision Engineering: Designed as a high-quality replacement, this 54.45mm single-ring piston provides an ideal solution for engine rebuilds requiring a +0.50mm overbore.\n\nVertex cast pistons are the industry standard for two-stroke engines. By combining superior material science with precise manufacturing, they deliver a component that balances performance, strength, and engine longevity effectively.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/husqvarna-crwrsm-125-1997-2013-050mm-oversize-5445mm-single-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.
