As I remember, the CJ360's were decontented CB360's designed to hit a lower price point, with 5-speeds, plastic front fenders, and drum front brakes. The CB360's got the six-speed and front disc.
The CJ did have better styling though. The CB360's never got the look quite right with their kicked up pipes.
This one does appear to be in very nice shape. I suspect the reserve on it is up at $1500+.
