Engineered for superior strength and efficient heat transfer, this piston is designed to optimize combustion and withstand demanding conditions.\n\nThe innovative elliptical design of this piston plays a crucial role in distributing thrust loads evenly across the cylinder wall. This reduces localized pressure points and prevents premature wear, contributing to a longer engine life and consistent performance. Manufactured with precision in Germany, Wossner pistons are recognized for their exceptional quality and reliability.\n\n### Key Features:\n\n\t\n- Forged Construction: Provides exceptional strength and durability over cast pistons.\n\t\n- Optimized Heat Transfer: Designed for efficient management of combustion temperatures, leading to improved performance.\n\t\n- Elliptical Piston Design: Ensures a uniform bearing surface even under extreme heat expansion, minimizing wear.\n\t\n- Even Thrust Load Distribution: Prevents localized pressure points and the risk of piston collapse.\n\t\n- German Engineering: Manufactured to high-quality standards in Germany.\n\n### Specifications:\n\n\t\n- Bore Size: 45mm (44.96mm)\n\t\n- Piston Part Number: 8241DA\n\t\n- Lock Part Number: CW12\n\t\n- Pin Part Number: WP091\n\t\n- Ring Set Part Number: RSB4500\n\t\n- Displacement: 63 cm&sup3;\n\t\n- Stroke: 40.80mm\n\t\n- Clearance: 0.04mm\n\t\n- Compression Ratio: 2-stroke\n\t\n- Compression Height: 21.60mm\n\n### Cross-Reference OEM Part Numbers:\n\n\t\n- 46030007500\n\t\n- 09104890\n\t\n- 864M04500","weightGrams":null,"fitments":[{"make":"GASGAS","model":"MC 65","cc":null,"notes":null,"years":"2021–2025"},{"make":"HUSQVARNA","model":"TC 65","cc":null,"notes":null,"years":"2017–2025"},{"make":"KTM","model":"65 SX","cc":null,"notes":null,"years":"2009–2025"},{"make":"KTM","model":"65 XC","cc":null,"notes":null,"years":"2009–2021"}],"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-09-20-ktm65-sx-450-forged-wossner-8241da-46030007500","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/5207de99dd51:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/5207de99dd51:1"}},"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.
