Crafted using a high-quality gravity cast aluminum alloy with an 18% silicon content, this piston is specifically designed to meet the unique demands of two-stroke performance, offering superior durability compared to standard cast alternatives.\n\nThe high silicon content provides essential advantages for engine health and power output. By significantly decreasing thermal expansion, the piston maintains its geometry even at high operating temperatures. This allows for tighter clearances, which translates into increased power, reduced mechanical noise, and a longer service life for your engine components.\n\n### Key Features\n\n \n- Advanced Alloy Composition: Manufactured with 18% silicon content to ensure exceptional strength and heat resistance.\n \n- Reduced Thermal Expansion: Minimizes geometry changes during operation, allowing for tighter tolerances and improved engine efficiency.\n \n- Optimized Wear Resistance: Specifically formulated to decrease skirt wear, effectively prolonging the lifespan of the piston and cylinder.\n \n- Precision Engineering: Designed to offer a perfect balance of power, performance, and durability for two-stroke applications.\n \n- Single Ring Design: Engineered to minimize friction while maintaining a consistent seal for reliable compression.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/husqvarna-crwr-250-1985-1991-grade-ab-6995mm-single-ring","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/83091f78f1b2:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/83091f78f1b2:1"}},"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.
