Forged in Germany, it is designed to maximise heat transfer from the combustion chamber to the cylinder walls. The elliptical piston shape promotes even distribution of thrust loads under heat expansion, reducing localised stresses and preventing piston collapse.\u003c\/p\u003e  \u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e  \u003cul\u003e \t\u003cli\u003e \t\u003cp\u003eForged construction for enhanced strength and resilience\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eOptimised for efficient heat transfer to cylinder walls\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eElliptical design for uniform load distribution under thermal expansion\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: 69mm (actual size 68.94mm)\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003ePart Number: 56-W642_200.WO\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 x 2\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eDisplacement: 246 cm³\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eStroke: 70.80mm\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eClearance: 0.06mm\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 \t\u003cli\u003e \t\u003cp\u003eCompression Height: 37.00mm\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\u003ePiston: 12110-28C11-0F0, 12110-29E20-0F0\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eRing, Piston: 12141-41600, 12141-41620\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003ePin, Piston: 12151-28C00, 12151-37F00\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003eCirclip: 09381-18002\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\u003e1989-1995 Suzuki RM250\u003c\/p\u003e \t\u003c\/li\u003e \t\u003cli\u003e \t\u003cp\u003e1993-1995 Suzuki RMX250\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.
