Forged in Germany, the piston is built for strength and thermal efficiency, enabling optimal heat transfer from the combustion chamber to the cylinder walls. Its elliptical shape ensures a uniform bearing surface during thermal expansion, reducing localised stress and helping to prevent piston collapse.\u003c\/p\u003e  \u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e  \u003cul\u003e \t\u003cli\u003e \t\u003cp\u003eForged piston for increased strength and reliability\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eEngineered to support effective combustion heat transfer\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eElliptical design promotes even thrust load distribution\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eManufactured 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: 67.00 mm\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eActual piston diameter: 66.94 mm\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eDisplay (cm³): 246\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eStroke: 72.00 mm\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 height: 38.00 mm\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eWossner compression ratio: 2-stroke\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eOEM compression ratio: 2-stroke\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 Part Number: 8156D100\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eLock Part Number: CW18\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003ePin Part Number: WP033\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eRing Set Part Number: RSB6700 x2\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eAlternate Part Number: 56-W526.P4.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\u003eHonda CR250R 1984\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eHonda CR250R 1985\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eHonda ATAC250 1984\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eHonda ATAC250 1985\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eHonda ATC250R 1985\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eHonda ATC250R 1986\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eHonda TRX250R 1985\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eHonda TRX250R 1986\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.
