This forged piston ensures high strength, efficient heat transfer, and durability. Its elliptical design provides a uniform bearing surface under heat expansion, reducing localized pressure and evenly distributing thrust loads to prevent piston collapse. Manufactured in Germany, this piston meets OEM compression standards.\n\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\t\u003cli\u003eHigh-strength forged piston for durability and performance\u003c\/li\u003e\n\t\u003cli\u003eOptimized heat transfer for efficient combustion\u003c\/li\u003e\n\t\u003cli\u003eElliptical design prevents piston collapse and ensures even load distribution\u003c\/li\u003e\n\t\u003cli\u003eManufactured in Germany\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\u003eBore: 69mm\u003c\/li\u003e\n\t\u003cli\u003eActual diameter: 68.94mm\u003c\/li\u003e\n\t\u003cli\u003eDisplay (cm³): 398\u003c\/li\u003e\n\t\u003cli\u003eStroke (mm): 55.50\u003c\/li\u003e\n\t\u003cli\u003eClearance (mm): 0.05\u003c\/li\u003e\n\t\u003cli\u003eCompression Ratio: OEM\u003c\/li\u003e\n\t\u003cli\u003eOEM Compression Ratio: 11.10:1\u003c\/li\u003e\n\t\u003cli\u003eDome Volume (cm³): -0.20\u003c\/li\u003e\n\t\u003cli\u003eCompression Height (mm): 22.80\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\u003eLock: CW18\u003c\/li\u003e\n\t\u003cli\u003ePin: WP033\u003c\/li\u003e\n\t\u003cli\u003eRing Set: RSB6900 X 2\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\u003eSuzuki RM250 (1977-1981)\u003c\/li\u003e\n\t\u003cli\u003eSuzuki PE250 (1977-1981)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e","brand":"Wossner","offers":[{"title":"Default Title","offer_id":50697784262922,"sku":"56-W474+P8.WO","price":161.79,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0846\/0094\/6954\/files\/stock54980_1.jpg?v=1738346182","url":"https:\/\/store.phoenixmotos.com\/products\/piston-kit-77-81-rm-pe250-69-0-forged-wossner-8194d200","provider":"Phoenix Motos","version":"1.0","type":"link"}
