The tank is too big and the drive is the wrong side to be a Sportster, it'll have a name that involves a handful of scrabble letters and something-Glide. It has rear suspension units so it is not one of the soft tail types either. It is probably an FX*** model.
Here it is FXD Dyna Super Glide, circa 2008. - Link to "www.motorcyclespecs.co.za"
