Which is right for me? Dual sport? or Motard?

Hello everyone! Recently ive been looking for a great commute bike. i didnt want anything flashy. so no sports or cruisers for me. So ive been looking at the Dual Sport and SuperMoto market for nice bikes. Now my question is, does anyone know what choice would be best for me? i would be riding nothing but road. no offroad stuff for me. And there would be virtually NO highway. unless there was absolutely NO other way to get to where i want to go. which would be rare. Im about 5'10" 250 pounds to help with the process of helping me. i WAS looking at the honda motard they have. that CRF something or other but turned away seeing as it only had about 14 hp or so. the Kawasaki KLX 250SF looks like it would be great but still not sure. the yamaha TW200 looks good too. and i know Suzuki has some great models. if ANYONE could help at ALL it would be greatly appreciated!
