Hi Steam, I did that about an year ago, during the dry season and it was relatively easy (Me on a 1200GS and a friend on a 1150GS). I assume you are coming from Calama heading to Uyuni, crossing the border at Ollague in Chile and Abaroa in Bolivia? About 400km of decent ripio (dirt) and very desert; during some stretches you will need to ride standing but not a big deal really, I´m far from being an offroad expert and had no problem; cannot tell, however, how it is like in case it rains. With the 25l tank on the 1150 fuel should not be an issue. Take everything you need, particularly water and snacks, first aid kit etc.

The road is *very* scenic and, approaching Ollague, you will see two of the most beatiful "salares" I´ve ever seen, Ascotán and Carcote, right next to the omnipresent Ollague volcano. After crossing the border, head to Uyuni via Via Allota and *not* Rio Grande; the road via Rio Grande, so I was told, has some traffic and trucks. The road via Via Allota is totally desert, with breathtaking views. Doable in one day if you leave Calama early and ride slowly enjoying the scenery. As others have said, if it is dry at the Salar de Uyuni, reserve at least one full day for riding on the salar itself and, if possible, plan to camp there for at least one night. You won´t regret it.

Enjoy your trip, you won´t forget it!
