72 honda cb-350 Fun to work on, light, good starter bike. toped at indicated 130. It rides a little stiff, and by no means is a performance bike, but you can get em on ebay for a hundred or so, work on em a little, and go ride. Bonus, if you lay it down, parts are all over ebay for cheap as hell.
1973 honda cb-450 parts bike, motor locked up. for $15, im getting my money out of it.
1977 honda cb-750 HEAVY dont know how well it rides, only got to put about 50 miles on it before i got deployed, havent gotten it back on the road since. Worth the $100 i paid for it though.
