I own a 1983 FXSB and was told that she was a special edition. It is painted Harley orange and black from the factory and has primary belt and secondary belt drive. Is this a normal FXSB ,or were all these models equipped with dual belt drive systems? I have never seen one painted with these unique colors (black and orange)Can someone help me out as to what I have,or is buddy(previous owner) telling me a tall tail?
