The DR 750 S Big it was build for racing, but became a big single off/roader. The models before 1991 are the best choice for really long distances with their enormous gasoline tank and the possibility of getting lots of packing with you. The exhaust was placed relative low that makes it possible for fastening saddlebags without risking burning them up. On the other hand, the saddle is not that comfortable on the older models.
