Moin Forum, I’ve fulfilled my little dream and bought me a big dog “Pit Bull ” 2 months ago. The moped is built in 2003 and has the ” small S&S engine with 107 cui. Small sounds already somehow sweet when you think that the moped has according to performance diagram 109 Ps from 1800 cc. I would have been terressed once if there were even more Big Dog or Iron Horse riders and would have liked to share experience. So biker, report and tell you what you have for experience and expect a and have your mopeds.
