Found this for sale advertised as a 1966/1967 175 Dual Sport. I know BS made a 175 Dual Twin street bike and Hurricane Scrambler, but were there any other 175cc models made? I always thought of a dual sport bike as an on/off road, like the Hurricane Scrambler. I am assuming this gentleman does'nt quite know what he has here. VIN is 18 B xxxxxx. Any thoughts?
