I regard 'SPORT' with the same derision as I do for the words 'HEAVY DUTY' and 'SPECIAL'People do weird things to their bikes, like adding "Sport" to the badging. No such model on the 650. Much like the guy who turned his "6" upside down and got everyone excited that there was a "Burgman 950" coming out.
My friend bought a Sym Citycom that someone stenciled "Ducati" on to it. It was quickly referred to as the "Duchcati". lol.
