I'm far from my maps, but if you're asking about the main road into town, it's paved and fine for whatever your ride. There are other roads, some listed as pistes on the Michelin, but I was told that these were fine as well (didn't get to check them out personally).
I stayed at Hotel France, which was otherwise empty of tourists. Food there was pretty basic, pricing negotiable if this is done in advance when you've still got leverage. Parking was "secured" by a guard with a taste for date wine (which, on the plus side, he was entirely willing to share) Lots of "guides" hanging around waiting for springtime and the return of the Europeans with their susceptibility to all the usual low-key scams.
I liked the falls and the surrounding area. Several hotels. Lots of trekking and camping possibilities once warmer weather arrives, but apparently lots of tourists as well. Lots of paved twisties and unpaved tracks for your motorcycling pleasure.
Hope that helps.
