Some russian mopeds have manual transmission.They have 1.st , neutral and 2.nd gear. I have Delta 24 ('88 I think). They have either hand gear lever or foot gear lever. Hand ones are not so good, because some of them will break but foot ones are good.
These old russian mopeds have lot of potential for a person, who wants to "tune" them illegal since low compression(I use 80 octane gasoline). You just have to make the compression bigger by grinding the cylinder head smaller and use some other octane gasoline (something like 95 or 98). I haven't changed anything since it may backfire to me.
