I like the yellow Vortex in the 3rd picture.I bet you that one just purrs like no other.
I must admit that's a very interesting 500 Twin you have there.Never seen that model with the chocolate brown cowl from a gold supreme before.
It also has the wrong back wheels on it.I think those ones are from the early seventies not the mid seventies.
It is a nice collection you have there,but I can't help the feeling that you have more as I can see some in the background.

Here for a good time,not a long time.
