The forged construction allows for a more optimized design compared to cast pistons, leading to improved performance and longevity.\n\n**Key Features:**\n\n\t\n- Forged Piston: Provides enhanced strength, a lighter weight, and allows for a more precise and advanced design for optimal combustion.\n\t\n- Optimized Heat Transfer: Designed to efficiently transfer heat away from the combustion chamber to the cylinder walls, promoting consistent operating temperatures and reducing the risk of pre-ignition.\n\t\n- Elliptical Design: The piston features an elliptical skirt design which ensures a uniform bearing surface on the cylinder wall, even under extreme heat expansion. This reduces localized pressure points and prevents piston collapse for a smoother, more reliable operation.\n\t\n- Manufactured in Germany: Built with precision and quality assurance in Germany, ensuring high standards of engineering and materials.\n\n**Specifications:**\n\n\t\n- Bore: 72.50mm (This is a +0.02mm oversize piston)\n\t\n- Standard Size Piston Part Number: 8163DC\n\t\n- Lock Part Number: CA18\n\t\n- Pin Part Number: WP033\n\t\n- Ring Set Part Number: RSB7250 (Includes 2 rings)\n\t\n- Engine Displacement: 247 cm&sup3;\n\t\n- Stroke: 60.00mm\n\t\n- Piston to Cylinder Clearance: 0.04mm\n\t\n- Compression Height: 28.75mm\n\t\n- Theoretical Weight: 204.00g","weightGrams":null,"fitments":[{"make":"GAS-GAS","model":"TXT 250","cc":null,"notes":null,"years":"2002–2020"}],"collections":[{"name":"Engine","url":"https://www.2brosparts.com/api/agent/collection/GB/engine"},{"name":"Pistons & Kits","url":"https://www.2brosparts.com/api/agent/collection/GB/pistons-kits"}],"links":{"page":"https://www.2brosparts.com/products/piston-kit-01-2020-txt250-gasgas-forged-wossner-8163dc","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/c48ece825e18:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/c48ece825e18:1"}},"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.
