Engineered for all Speedway applications, including GM Speedway 499cc engines, this piston kit is manufactured in Germany to provide exceptional strength and superior heat management. The elliptical piston design is crucial for even expansion and consistent pressure distribution under thermal load. This design minimizes stress, helping to prevent piston failure in high-performance racing environments.\n\n#### Key Features:\n\n\t\n- Forged construction ensures superior strength and long-lasting durability.\n\t\n- Designed for efficient heat transfer from the combustion chamber to the cylinder walls.\n\t\n- Elliptical piston profile maintains a consistent bearing surface as the piston expands with heat.\n\t\n- Promotes even thrust load distribution, reducing localized stress on the piston.\n\t\n- Precision manufactured in Germany.\n\n#### Specifications:\n\n\t\n- Bore Size: 92.00mm (2.02mm Oversize)\n\t\n- Actual Measured Bore: 91.94mm\n\t\n- Engine Displacement: 499 cm&sup3;\n\t\n- Stroke: 78.50mm\n\t\n- Piston to Cylinder Wall Clearance: 0.08mm\n\t\n- Dome Volume: +5.60 cm&sup3;\n\t\n- Compression Height: 22.00mm","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-gm-speedway-9200-wossner-8811d200c","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/191970589364:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/191970589364:1"}},"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.
