First of all, I don't know much about adventure riding and in general you surely know more than me if you ride in the woods.
However, for example some months a go there was a guy with an ADV bike riding in a motocross track. I was the wierdo with an E bike and he was the wierdo with an ADV bike and so we socialized and asked each other questions about our respective curious bike choices

. He said that he was there to train for his expeditions and that he traveled abroad to places like Morocco and I also heard other people saying thet they do similar things with ADV bikes.
An AI just told me that, for example, in Morocco it is currently still way easier to find a gas station.
Now, if most of the European ADV bike users just use the bikes to ride on the Alps or similar places, then maybe it's not a big problem, although remember that if you run out of fuel in some wood you can solve the issue by finding someone who can bring you a gas tank, while with an EV you would either need someone to bring you a power station to charge the bike with the time needed to do so or you would need a vehicle capable of transporting your bike out of there.
The way I see it, doing adventures with a motorcycle can be scary regardless of the bike that you use and it's better to reduce anxiety and danger, which, it seems to me, that won't be achieved with an EV having a less than a very good range.
When I talked to that guy from the motocross track about use of EVs for adventure, he said that some pople have even done the Dakar race with EVs but that they were heavily assisted in a way that made it way more complicated and expensive than using gas bikes.
BTW I expect Stark to race in the Dakar some day.
