Designed with precision and durability in mind, this piston ensures your engine maintains optimal performance and reliability under demanding race conditions.\n\n### Advanced Gravity Casting Technology\n\nVertex pistons are manufactured using a gravity casting process with a specialized aluminum alloy containing 18% silicon. This specific composition is ideal for two-stroke applications, offering superior thermal stability and structural integrity compared to standard components.\n\n### Key Features and Benefits\n\n \n- Reduced Thermal Expansion: The high silicon content minimizes thermal expansion, allowing the piston to maintain its shape even at operating temperatures. This permits tighter tolerances, leading to increased power and improved overall performance.\n \n- Enhanced Durability: The material composition provides excellent wear resistance, significantly extending the lifespan of both the piston and the piston skirt.\n \n- Precision Engineering: Designed for efficiency, this single ring configuration reduces friction to allow for faster throttle response and smoother engine operation.\n \n- Reliable Performance: By minimizing the risk of mechanical rattling or skirt breakage, this piston provides peace of mind for riders who push their machines to the limit.\n\n### Technical Specifications\n\n \n- Brand: Vertex\n \n- Component Type: Two-stroke Race Piston\n \n- Grade: D\n \n- Diameter: 53.97mm\n \n- Configuration: Single Ring","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/husqvarna-tctesm-125-2014-2023-grade-d-5397mm-single-ring-race-piston","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/fc966712c432:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/fc966712c432:1"}},"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.
