I own a 83 FXSB and I think it is an awsome ride with good looks and plenty of parts still available. Never thought I would like a belt drive and this one proved me wrong. It is a keeper for me ,as I have had two prior Harleys and none was like this one. It is the only big twin that I have rode that could be speed shifted. I have a question about it´s back ground and this 83 has a primary and secondary belt drive. Is this common for the FXSB´s. After all I always thought FXSB stood for FX Single Belt. Would this be a FXSB Sturgis model? I was told they made these models for a short time period. It has also a paint scheme which the previous owner said was a speacial edition colour(Harley´s Racing Orange and Black.)The paint is original and I know,as I am a 25+ years being a automotive painter. Can some on tell me a little more about my bike? Thx. for any information. Mike Monkman
