This German-manufactured piston offers excellent thermal management and mechanical reliability. Its elliptical profile provides a consistent and uniform bearing surface during thermal expansion, minimising high-stress zones and reducing the risk of piston collapse during intense use.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\t\u003cli\u003e\n\t\u003cp\u003eForged construction delivers high durability and strength under extreme load\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003eElliptical design reduces localised pressure and distributes thrust evenly\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003eEnhanced heat dissipation from combustion chamber to cylinder walls\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003ePrecision engineering and manufacturing in Germany\u003c\/p\u003e\n\t\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\t\u003cli\u003e\n\t\u003cp\u003eBore: 49.00 mm\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003eActual Piston Diameter: 48.95 mm\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003eStroke: 47.80 mm\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003eDisplacement: 82 cm³\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003eClearance: 0.05 mm\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003eCompression Height: 26.00 mm\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003eWossner Compression Ratio: 2-stroke\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003eOEM Compression Ratio: 2-stroke\u003c\/p\u003e\n\t\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eCross-Reference OEM Part Numbers\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\t\u003cli\u003e\n\t\u003cp\u003eWossner Piston: 8188D200\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003eLock: CW14\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003ePin: WP058\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003eRing Set: RSB4900\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003eRod: P2008\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003eInternal Part No: 56-W646+200.WO\u003c\/p\u003e\n\t\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eVehicle Fitments\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\t\u003cli\u003e\n\t\u003cp\u003e1993 Yamaha YZ80\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003e1994 Yamaha YZ80\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003e1995 Yamaha YZ80\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003e1996 Yamaha YZ80\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003e1997 Yamaha YZ80\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003e1998 Yamaha YZ80\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003e1999 Yamaha YZ80\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003e2000 Yamaha YZ80\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003e2001 Yamaha YZ80\u003c\/p\u003e\n\t\u003c\/li\u003e\n\u003c\/ul\u003e\n","brand":"Wossner","offers":[{"title":"Default Title","offer_id":61520625074510,"sku":"56-W646+200.WO","price":92.11,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0844\/6502\/5358\/files\/stock56254_1.jpg?v=1793708632","url":"https:\/\/btpsouthwest.uk\/products\/oro2u-56-w646-200-wo-257308","provider":"BTP - Braydon Trailers \u0026 Powersports | Sales, Hire, Parts, Servicing \u0026 Repairs","version":"1.0","type":"link"}
