No. Any inexpensive derailleur will work in friction mode. Shimano sells I think the tourney and the Alivio with hangers and without. But if your moto has a derailluer hanger already (as in it's part of the dropout) it might be an older type and it may not be long enough to use with a modern derailluer. I suppose you could bypass though and use a separate hanger anyway.
You can also buy a derailluer hanger by itself (made by sunrace) if you have an old derailleur hanging around to use. I put an Alivio derailluer on my wife's 70's nishiki and it's great. You could also consider Sunrace derailleurs if you wanted. They carry them here: http://www.biketoolsetc.com/index.cg...lleurs&tc=Rear
As for the stem mounted shifters, Sunrace still makes some but I believe they're index only. You could probably get some old ones for next to free either from ebay or a forum member. Hardly anyone likes them anymore, but they came on a lot of bikes in the 70s.
