Keep indecisive scooter Honda PCX 125 or switch to motorcycle

Dear community, unfortunately I am very undecided about the decision between scooter and motorcycle. The brand is relatively certain and should continue to be Honda. It would be so easy if my weight were not. I am unfortunately very overweight and bring about 135 – 140 KG at 185cm on the scales. Most smaller motorcycles (125er) look more like an elephant on a tricycle or? Currently I drive a Honda PCX 125 scooter. But I am always with a scooter you are unfortunately not really a part of the biker community. I also found that longer tours over 100 km become quite uncomfortable for the back. Is this still worse with motorcycles? I am sure that a super sportsman is not in question for me. In the last week I drove his Daelim VT 125 test by a friend to see if the manual switch I found it very pleasant to ride with it, but unfortunately the motorcycle and also the technology has already come into the years. Alternative to the Daelim VT 125 would be a Honda Shadow or a Honda Rebel. Here, however, the outdated technology (gasifier) and the higher fuel consumption bothers me. I find a gasoline direct injection best, because the vehicles always start with it and the fuel consumption is optimized. Unfortunately Honda has no chopper similar model with aktu The newer Honda Rebel starts at 250ccm. The only two motorcycles I can imagine at the moment would be the Honda CB125R or the CB125F. However, I am not sure if it would be an improvement of comfort and especially of the optical :-). How do you see that? 135 KG on the 125ers a problem or ok? Thank you very much for your decision support.
