Manufactured from a premium aluminum alloy containing 18% silicon content, this piston is designed to optimize engine performance, thermal efficiency, and durability.\n\n### Key Features\n\n \n- High Silicon Content: The 18% silicon composition significantly decreases thermal expansion, allowing the piston to maintain its geometry even at high operating temperatures.\n \n- Tight Tolerances: Reduced thermal expansion enables these pistons to operate at tighter tolerances than traditional forged pistons, resulting in superior power delivery and improved engine response.\n \n- Extended Service Life: The advanced alloy composition provides excellent wear resistance, particularly on the piston skirt, which helps to prolong the life of both the piston and the cylinder.\n \n- Precision Engineering: Designed for reliability, this piston is less susceptible to breaking or rattling, providing peace of mind during demanding riding conditions.\n \n- Single Ring Configuration: Optimized for efficient combustion and reduced friction, this single-ring design is tailored for high-output two-stroke applications.\n\nVertex pistons are the preferred choice for riders and mechanics looking for a high-quality replacement that balances power, longevity, and reliability. By utilizing gravity casting technology, Vertex ensures a consistent, high-quality product that meets the specific demands of two-stroke engine mechanics.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/husqvarna-crwrsm-125-1997-2013-grade-d-5397mm-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.
