I believe that it is more a matter of style. The C50 has lots more "dresser" accessories available, while the S50 leans toward chopper styling with nothing extra hung on to interfere with the naked lines. The S50 is nearly 100lbs lighter, so that has to help a tad, in terms of power. My preference leans toward the S50, as I keep the 2005 model in Maryland, while the VS800 Intruder stays in Florida. I have not found a need to hang on saddle bags, but I do carry the bungie net, so I can pick up a couple groceries or other items and lash same to the sissy bar, using the bungies. Works for me, but others find a need for more luggage space. I had dresser Harleys in the past and that is what the C50 looks like to me. The C50 is what I call a fat bike, with the heavy looking front tire and fender. When it comes right down to it, the rider has to decide what he likes and these days, what image he wishes to portray.
I am perfectly happy with the two light weight 800cc bikes, but in my dreams, I ride a "Road Warrior", all black with no chrome and a terrible quantity of horsepower that I would probably never use!! How important is the dream, when weighed against the reality?
