The forged, elliptically designed piston ensures a more uniform bearing surface during heat expansion, minimising localised pressure and evenly distributing thrust loads to prevent piston collapse. Manufactured in Germany, this kit includes the necessary components for a durable rebuild and is suitable for 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 longevity\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eOptimised for efficient combustion chamber heat transfer\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eElliptical design provides a uniform bearing surface under heat expansion\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eMinimises 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: 72.01mm (Actual 71.94mm)\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 (+0.01)\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\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\u003eMajority of our listings are for a direct replacement for your original part.\u003c\/p\u003e\n\u003cp\u003eOur parts are made of quality and are designed to meet or exceed the original OEM Standards.\u003c\/p\u003e\n\u003cp\u003eOur products are often a cost effective alternative to genuine OEM Parts.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note: \u003c\/strong\u003ethe models of bike we state in our listings are for general guidance only.
