Engineered specifically for high-performance two-stroke engines, this piston is designed to deliver reliability, power, and precise tolerances for your machine.\n\nVertex pistons are manufactured using a gravity-cast process from an advanced aluminum alloy containing 18 percent silicon. This specific material composition is selected to meet the unique demands of two-stroke operation, where efficient heat management and wear resistance are critical.\n\n### Key Features\n\n \n- High Silicon Content: The 18 percent silicon blend significantly decreases thermal expansion. This allows the piston to maintain its geometry as it reaches operating temperatures, enabling tighter running tolerances compared to forged alternatives.\n \n- Enhanced Durability: The material composition provides superior wear characteristics, effectively prolonging the lifespan of the piston by reducing friction and wear on the piston skirt.\n \n- Optimized Performance: By reducing thermal expansion and ensuring a precise fit, these pistons help minimize rattling and improve overall engine efficiency.\n \n- Precision Engineering: Designed for riders who demand consistency, this Grade A piston ensures an exact fit for your engine configuration to restore compression and throttle response.\n \n- Two-Stroke Specialized: Specifically optimized for the lower cylinder pressures found in two-stroke engines, providing an ideal balance between weight, strength, and longevity.\n\nWhether you are performing a routine top-end rebuild or restoring your engine to factory specifications, Vertex provides the quality components required to keep your bike running at its best on the track or the trail.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/husqvarna-te-150i-2021-2023-grade-a-5794mm-single-ring","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/506288c4d661:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/506288c4d661:1"}},"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.
