Silicon decreases thermal expansion, allowing for tighter tolerances and improved power and performance.

Engineered specifically for two-stroke engines, this high-quality gravity cast piston is designed to meet the rigorous demands of motocross and off-road riding. By utilizing an advanced aluminum alloy with an 18% silicon content, Vertex provides a piston that balances strength with precision engineering.\n\nThe high silicon content serves two critical functions in your engine. First, it significantly decreases thermal expansion. This allows the piston to maintain its geometry even at high operating temperatures, enabling tighter tolerances compared to forged alternatives. Tighter tolerances translate directly into improved power delivery and a smoother, more efficient engine run.\n\nSecond, the specialized alloy provides excellent wear characteristics. By reducing friction and wear on the piston skirt, this component helps extend the service life of your engine, giving you more time on the track and less time in the garage.\n\n### Key Features\n\n \n- Advanced Alloy Composition: Gravity cast aluminum with 18% silicon content for maximum durability.\n \n- Minimized Thermal Expansion: Maintains stable dimensions at operating temperatures for tighter, more efficient tolerances.\n \n- Optimized Performance: Engineered to reduce piston rattle and increase overall engine power output.\n \n- Extended Longevity: Superior wear resistance helps prolong the life of the piston skirt and the surrounding cylinder components.\n \n- Two-Stroke Specialist: Specifically formulated for the lower cylinder pressures of two-stroke engine environments.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/husqvarna-cr-65-2011-2013-grade-ef-4498mm","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/3d64db4bcec1:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/3d64db4bcec1:1"}},"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.
