Manufactured in Germany, it incorporates a precision-engineered elliptical design that evenly distributes thermal expansion stresses across the bearing surface. This reduces localised pressure and prevents piston collapse. The piston supports efficient heat transfer from the combustion chamber to the cylinder wall, enhancing engine stability and longevity in high-performance two-stroke applications.\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 piston construction for high durability\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003eElliptical profile ensures uniform expansion and stress distribution\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003eReduces risk of structural failure under operating heat\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003eSupports combustion heat transfer for consistent engine performance\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003eEngineered and manufactured 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 Size: 68.02mm (+0.02mm oversize)\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003eActual Diameter: 67.96mm\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003eCompression Height: 38.00mm\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003eStroke: 72.00mm\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003eDisplacement: 249 cm³\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003ePiston Clearance: 0.06mm\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003eCompression Ratio: 2-stroke (Wossner and OEM)\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 Kit Part No: 8023DC\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003eAlternate Piston PN: 8058DC\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003eLock: CW18\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003ePin: WP033\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003eRing Set: RSB6640 x2\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003eRod: P2026\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\u003e1996 Suzuki RM250\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003e1997 Suzuki RM250\u003c\/p\u003e\n\t\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Wossner","offers":[{"title":"Default Title","offer_id":49342940774682,"sku":"56-W681.C.WO","price":169.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0795\/6096\/6426\/files\/stock56412_4.jpg?v=1744260512"},{"product_id":"257465","title":"Wossner Piston 96-97, 99 RM250 66.40, Wossner 8058db Suzuki MX","description":"\u003cdiv style=\"   border-left: 6px solid #ffcc00;   background: #fff9e6;   padding: 10px 12px;   margin: 12px 0;   font-size: 14px;   line-height: 1.35;   color: #111;   border-radius: 6px; \"\u003e   \u003cstrong style=\"font-size: 15px;\"\u003e⚠️ Fitment note:\u003c\/strong\u003e   The Make\/Model filter is for guidance only.
