Produced in Germany from high-strength forged materials, this piston ensures durability and efficient heat transfer. Its elliptical design promotes even load distribution under heat expansion, minimising localised stress and reducing the risk of piston collapse. The kit includes all necessary components for a reliable and precise engine rebuild.\u003c\/p\u003e  \u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e  \u003cul\u003e \t\u003cli\u003e \t\u003cp\u003eForged piston offers enhanced strength and heat resistance\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eDesigned for efficient combustion chamber heat dissipation\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eElliptical profile distributes thrust loads evenly during thermal expansion\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eReduces localised pressure and risk of piston deformation\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eManufactured in Germany with high precision\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: 66.50 mm\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eActual Bore Diameter: 66.44 mm\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eStroke: 57.00 mm\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eDisplay Displacement: 199 cm³\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eClearance: 0.06 mm\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eCompression Ratio (Wossner and OEM): 2-stroke\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eCompression Height: 29.90 mm\u003c\/p\u003e \t\u003c\/li\u003e \u003c\/ul\u003e  \u003cp\u003e\u003cstrong\u003eCross-Reference Wossner Part Numbers\u003c\/strong\u003e\u003c\/p\u003e  \u003cul\u003e \t\u003cli\u003e \t\u003cp\u003ePiston Kit: 8101D050\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eLock: CW16\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003ePin: WP027\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eRing Set: RSB6650 (Quantity: 2)\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eRod: P2030\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003ePart No.: 56-W573+050.WO\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\u003eYamaha YFS200 Blaster (1988–2006)\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.
