I am selling my 2 mopeds. The 1980 Sachs Prima is stock. It is in pretty good shape besides the exhaust being a little scratched up. The 1978 Motobecane has a 70cc kit with less than 100 miles on it and a 15mm Dellorto carb. The Sachs does about 30 of course and the Motobecane does 45 to 50 depending on your weight and such. It could probably go a bit faster with a better exhaust. The kit was probably the hardest upgrade, so it could be fun for someone who is looking for something faster that isn't a huge pain.
I live near Harlem and Milwaukee. I'm looking for $550 for the Sachs and $750 for the Motobecane. I'm willing to negotiate if I don't get many offers.
