Sure, no problem, it all depends offcourse of how good you are one a bike (or how young?). I rode toghether with a guy on a suzuki freewind with tourances and 40 kg of luggage, and we did every condition possible in Morocco, with no problems whatsoever.
If you check my youtube channel you will find lots of video's of me and Dan on the suzuki:
