On the contrary there are several other manufacturers of mopeds left in the world. Unfortunately we can not get them, because the paper cost way too much money for the dealers. If I can remember correctly HB has not imported Heros in two years, and the last order for parts ( which BJ still has a peripheral of ) was last year when I got my engine.
As for the French connection, Moby parts do not match up, but Heros motors at one point in time wher talking to Peugeot, so maybe look there. I would love to find a 102 or 103 to do an comparison but for some strange reason central Ohio has vary few Pugs.
