The forged, elliptically designed piston ensures a uniform bearing surface during heat expansion, reducing localised pressure and evenly distributing thrust loads to prevent piston collapse. Made in Germany, this kit includes essential parts for a reliable rebuild and is compatible with KTM 300 models from 1990 to 1994.\u003c\/p\u003e  \u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e  \u003cul\u003e \t\u003cli\u003e \t\u003cp\u003eForged piston construction for superior strength and durability\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eEngineered for efficient combustion chamber heat transfer\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eElliptical design ensures uniform bearing surface under thermal expansion\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eReduces localised pressure and prevents piston collapse\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eMade in Germany\u003c\/p\u003e \t\u003c\/li\u003e \u003c\/ul\u003e  \u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e  \u003cul\u003e \t\u003cli\u003e \t\u003cp\u003eBore Size: 72.00mm (Actual 71.93mm)\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eDisplay (cm³): 297\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eStroke (mm): 72.00\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eClearance (mm): 0.07\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eCompression Ratio (Wossner 2-stroke): 2 stroke\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eCompression Ratio (OEM 2-stroke): 2 stroke\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eCompression Height (mm): 29.70\u003c\/p\u003e \t\u003c\/li\u003e \u003c\/ul\u003e  \u003cp\u003e\u003cstrong\u003eCross-Reference OEM Part Numbers\u003c\/strong\u003e\u003c\/p\u003e  \u003cul\u003e \t\u003cli\u003e \t\u003cp\u003eWossner Piston Kit Part No: 8012DA\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eLock Part No: CW18\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003ePin Part No: WP039\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eRing Set Part No: RSB7200 × 2\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eOEM Part Numbers: 54630015044, 631M07200\u003c\/p\u003e \t\u003c\/li\u003e \u003c\/ul\u003e  \u003cp\u003e\u003cstrong\u003eVehicle Fitments\u003c\/strong\u003e\u003c\/p\u003e  \u003cul\u003e \t\u003cli\u003e \t\u003cp\u003e1990 KTM GS300\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003e1990 KTM MX300\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003e1990 KTM EXC300\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003e1991 KTM GS300\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003e1991 KTM MX300\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003e1991 KTM EXC300\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003e1992 KTM GS300\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003e1992 KTM MX300\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003e1992 KTM EXC300\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003e1993 KTM GS300\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003e1993 KTM MX300\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003e1993 KTM EXC300\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003e1994 KTM GS300\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003e1994 KTM MX300\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003e1994 KTM EXC300\u003c\/p\u003e \t\u003c\/li\u003e \u003c\/ul\u003e\n\u003cp\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\n\u003c\/body\u003e","brand":"Wossner","offers":[{"title":"Default Title","offer_id":55594875158902,"sku":"REF 56-W631.A.WO","price":183.43,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0917\/7032\/3318\/files\/stock56117_1.jpg?v=1783536839","url":"https:\/\/www.awmotorcycleparts.co.uk\/products\/ref-56-w631-a-wo","provider":"AW Motorcycle Parts","version":"1.0","type":"link"}
