yes you can say touring bike but i think to take extremely rare part motorcycle on mountains is one difficult pressurized job where you pray not to break anything . but yes these bikes can be used as tour otherwise
i will say it will be fun to off-road on sand roads.
one group took there 2 stroke cruisers to mountains and they all were heavily restored like everything from original factory not single jugar. they were able to go high and fun without engine problems.
