Let us know how you got on in Morocco. I am also using what I have, taking my 13 year old Suzuki GS500 to Nigeria. In my opinion, there is no point in buying a new bike just for a trip and suffer afterwards in the city traffic or twisties in the weekends or whereever you spend you biking days otherwise. Plus there is the question of equipping the new bike with luggage, tyres, spare parts etc.
Just do as it was said, ride wherever you can and if you feel the need for it, rent a bike or join in to a group tour. I might do the same.
