one word ... minarelli
i have been indoctrinated into the virtues of the minarelli engine. i have to say that parts are easy enough to come by, the engine is very simple and easy to work on, and it comes on lots and lots of different mopeds (mostly italian, of course).
puchs are nice, as i'm sure tomos are, and motobecanes look slick ... but a nice vintage italian moped just looks so great cruising along the road ... and my bianchi is one of these beautiful italian bella donnas
