It always pains me to find cult bikes on Craigslist. They pop up from time to time but seem to only get rarer. I wish I could buy them but I'm in no position to be collecting bikes right now....
About five years ago there were a few Honda CB-1's for sale for relatively good prices and in good condition. Now I can only find one, but it still seems to be a decent deal.
FS: 1990 Honda CB-1 400cc motorcycle - Blue
400cc inline-four, would even make a great commuter bike in town! This one is even in the signature blue colour.
The Honda CB900C was a odd bike. A mash up of parts from other bikes and a quirky, unique transmission, there isn't anything quite like it. This one looks to be in fairly good shape.
