I like this first part from Wikipedia they included Yamaha ;D
For other uses of "Ténéré", see Yamaha XTZ 750.
The Ténéré (Berber: Tiniri, literally: desert, wilderness) is a desert region in the south central Sahara. It comprises a vast plain of sand stretching from northeastern Niger into western Chad, occupying an area of over 154,440 square miles (400,000 km²). Its boundaries are said to be the Aïr Mountains in the west, the Hoggar Mountains in the north, the Djado Plateau in the northeast, the Tibesti Mountains in the east, and the basin of Lake Chad in the south.
