Enduro riding in Southern Morocco.
See here for all you need for a desert & mountain Enduro adventure. The bikes are now KTM 400, CRF 450 Honda, and Yamaha TTR 250.
They can also supply bikes for independent tours.
When doing my own research on a potential tour to Morocco, I found these guys to be helpful and informative. Talk to Brad or Peter. All kinds of different itineraries availalble.
