Engineered for superior durability and efficiency, this kit is designed to enhance the power and longevity of your 4-stroke engine. Manufactured in Germany, Wossner pistons are renowned for their precision and quality.\n\nThe forged construction provides exceptional strength, enabling the piston to withstand higher combustion pressures and temperatures compared to cast pistons. This results in increased reliability and performance, especially under demanding riding conditions. The advanced elliptical design ensures a uniform bearing surface against the cylinder wall, which effectively distributes load, reduces localized pressure, and minimizes wear, ultimately preventing piston collapse and extending engine life.\n\n**Key Features:**\n\n\t\n- Forged aluminum construction for maximum strength and durability.\n\t\n- Optimized heat transfer for improved engine cooling and performance.\n\t\n- Elliptical piston skirt design for reduced friction and wear.\n\t\n- Precision engineered for optimal fit and function in 4-stroke engines.\n\t\n- Manufactured to exacting standards in Germany.\n\n**Specifications:**\n\n\t\n- Bore Size: 73.00 mm\n\t\n- Actual Bore: 72.94 mm\n\t\n- Stroke: 59.50 mm\n\t\n- Clearance: 0.06 mm\n\t\n- Compression Height: 25.00 mm\n\t\n- Dome Volume: +6.00 cm&sup3;\n\t\n- Compression Ratio: 10.50:1\n\t\n- OEM Compression Ratio: 9.30:1\n\t\n- Displacement: 249 cm&sup3;","weightGrams":null,"fitments":[],"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-86-04-xr250-7300-forged-wossner-8793da","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/121a1532a2db:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/121a1532a2db: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.
