Properly setup KLR won't be beat for this application. No, I don't own one but used to. I've owned or ridden all of these and more including the KTM and Husky as well. No doubt about what I'd take around the world. KLR.
90 percent of your ride will be paved/dirt road miles where the KLR excels over any of the other bikes. Your offroading won't be technical so the bike just needs to haul a lot and be passable here. The KLR is.
