CL77 scrambler--nice bike, fast for its day, those high pipes are a joy to look at. I would rather have a superhawk. If you are looking a friend has one for sale. Not cheap.
Dream 305-- rides like a cadillac, funky looks, either you love it or hate it. Easy to get parts. I have the jr. version dream 160 which I love, even if it is fugly. Readily available on ebay or your local shopper. There is a nice one in"want ad digest " here for $2500.
C201--not sure on this one. If you meant c200 its a 90cc pushrod engined bike. Kind of the dream of the 90's. Nice transport, funky, you won't have to worry about speeding tickets
S65--I just sold two of these. Not to powerful, looks like the c200 but with an overhead cam engine. Fun to ride, very light.
If you are interested in the c200 or s65, check out the Super 90. I lusted for one in 1967....
All of the above are RAPIDLY appreciating and more fun than the stock market. Parts are not too hard to find, especially if you don't mind buying from Thailand or other exotic locations. Sometimes the sheetmetal or plastic can be a little challenge, but hell, they made a hundred zillion of 'em.
