Isn't the whole point of adventure riding to ride 100s of kms from civilization? At least that is the romance the manufacturers promote and that is my point. Away in nothingness but yourself and your bike simplicity is king. The whole wrong way around set crazy expectations. These guys had a support crew and truck tagging along. 
I much preferred Ted Simon's approach the first time. A rebuild of the engine wasn't a big deal on that old Triumph.
False advertising! 
The trunk road I took in Panorama BC this summer looked like this and it was only 20 minutes from the main road. Another 20 minutes and I would probably be at the top so you can get to place that looks like this without going all out. It's not really false advertising, it's more selling a dream or showing the capacity of the bike.
You seam always have to turn it up to a 10 out of 10 or it's not adventure. Not everyone wants quit their job, leave their family behind and drive to the south pole to have an adventure, a day trip to Drumheller is fine. [emoji14]
Quite the opposite. Many people get themselves in bad situations because they think/were told/were shown pictures that it had the capacity to. While back roading in BC we come across adventure owners in bad situations. If the bike can be picked up by the owner it is a great place to start.
BTW the "trunk" road you were on is the Toby Creek Main. Follow it up and turn at Jumbo and you are presented with a small stream crossing the road. Cross in the morning and it's no big deal. Come back after a few hours and it is wide, deep and fast since it is sourced by glacial melt. Get on the wrong side of things and adventure adds up very quick!
Again, I think it depends on perspective.
My bro took his large-ish Adv bike to the Yukon and beyond. It's a fact that no other type of comfortable touring rig is doing the same trip with the same comfort and confidence. I saw some of the "roads" he had to use and no regular touring bike, let alone a car could do this trip via the route they took. And that's really something to a great many people. It doesn't have to be Baja level to be a worthwhile adventure or challenge.
And these bikes excel at that. They open up some trips for those with wanderlust. And all things considered, not a ton of dough either.
Heavy? Sure, some of them. Most guys doing a serious enough trip in serious enough conditions bring an off road moto hoist with them. 10lbs and can right an 800lb bike...even with you underneath it (provided the hoist is within reach of course).
These bikes can't do everything for everyone (like you). But for many, this type of adventure touring is their crack...
Personally, I really like the Transalp and would happily take it on sections of the Trans Canada. Sections within my and the bikes capability. Or up to the Yukon. Or logging roads in Northern Ontario.
Just...getting lost and riding.
