According to the article it was a three driver team that was swapping out regularly. Also, the bike was made full size by wrapping the thing in a huge fuel tank. Still, that's a long ride even on a full size bike.
Wrapping it won't lengthen the wheelbase or suspension so it will still turn in like a little bike. Still will be twitchy at speed like a little bike, and defo going to take pothole just like any other bike with little wheels, terribly.
Then you don't know the meaning of the word "comfort."
The B body, culminating in the Oldsmobile Delta 88 Royale Brougham LS (8th gen, "Body by Fisher") was a rolling couch you could sink into, with that ridiculously static-generating and uncleanable velour. Some Cadillacs and Lincolns were also okay, but Fisher put all other automotive brands, foreign and domestic, to shame in the comfort category.
A bit tangential, but this guy drove from Alaska to Argentina on a c90. It was a few years of sleeping in a tent, some random person's spare bedroom, or the cheapest hotel possible.
I couldn't imagine 4,000km on a knee-high 125cc bike.
They are very cool bikes though. I'd love to buy one, but I want to buy a Rebel first.
