Engineered for strength and precision, this piston ensures efficient heat transfer to the cylinder walls, providing uniform expansion and reducing localized pressure. The elliptical design distributes thrust loads evenly, preventing piston collapse. A hard Teflon skirt coating ensures a precise fit and optimal conformability to the cylinder bore. Manufactured in Germany, it meets high-quality standards for reliable performance.\u003c\/p\u003e  \u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e  \u003cul\u003e \t\u003cli\u003eWossner forged piston for superior strength and durability\u003c\/li\u003e \t\u003cli\u003eOptimized heat transfer for improved combustion efficiency\u003c\/li\u003e \t\u003cli\u003eElliptical design for uniform bearing surface and reduced localized pressure\u003c\/li\u003e \t\u003cli\u003eHard Teflon skirt coating for improved fit and reduced friction\u003c\/li\u003e \t\u003cli\u003ePrecision-engineered to prevent piston collapse\u003c\/li\u003e \t\u003cli\u003eMade in Germany\u003c\/li\u003e \u003c\/ul\u003e  \u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e  \u003cul\u003e \t\u003cli\u003eBore Size: 83.00mm (82.92mm)\u003c\/li\u003e \t\u003cli\u003eOversize: +1.00mm\u003c\/li\u003e \t\u003cli\u003eDisplacement: 438cc\u003c\/li\u003e \t\u003cli\u003eStroke: 83.00mm\u003c\/li\u003e \t\u003cli\u003eClearance: 0.08mm\u003c\/li\u003e \t\u003cli\u003eCompression Ratio: 2-stroke\u003c\/li\u003e \t\u003cli\u003eCompression Height: 41.70mm\u003c\/li\u003e \t\u003cli\u003eLock Part Number: CA18\u003c\/li\u003e \t\u003cli\u003ePin Part Number: WP039\u003c\/li\u003e \t\u003cli\u003eRing Set Part Number: RSC8300\u003c\/li\u003e \t\u003cli\u003eTheoretical Weight: Not specified\u003c\/li\u003e \u003c\/ul\u003e  \u003cp\u003e\u003cstrong\u003eVehicle Fitments\u003c\/strong\u003e\u003c\/p\u003e  \u003cul\u003e \t\u003cli\u003eMaico MC 440 (1973-1981)\u003c\/li\u003e \t\u003cli\u003eMaico MD 440 (1973-1981)\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.
