The bike was a Kawasaki KLR650.
The route was down through Europe, Morrocco and then into Algeria to explore the Sahara, before dropping south to Niger, Benin, Togo and Ghana.  Then heading east into Nigeria, Cameroon, Central African Republic, Zaire, Uganda and ... finally, Kenya.
Then I went to Iceland.

Throughout the text I have used the place names common at the time.
