For me adventure motorcycling is a state of mind which can occur on a longish trip.
I think the base factors (for me) are that I have to trust my own skills and equipment. The fact that there is impossible to get help (from friends, doctors, mechanics, no phone..) while I am in an unknown area might switch my brain to adventure-mode. If the culture is totally different and I don’t speak the local language the feeling gets stronger.
The logistic (fuel, water, food++ ) is a big factor.
It’s very difficult to get this state of mind if you travel with friend(s), and I have never had it unless there have been things as guns, total mechanical break down or injured people involved.
Pretty often I go on shorter trips in my own country and even if the driving might be pretty technical and far from people and help I wouldn’t call it “adventure motorcycling”, maybe “action touring”…. On these trips there is more focus on the driving. Logistical problems are few.
As an example I would say that riding in the dunes Algeria was “adventure motorcycling” but riding in the dunes in Namibia was not… In Namibia they had doctors, food,

s and even workshops available.
Luckily I enjoy both, but it are complete different situations even if might look similar.
This is just my personal thoughts; I don’t think there is an answer most people can agree on. What is love….?
