Funny thing, my wife just pointed out the whole 'crown of the road' explanation thing she discovered on Quora.
It is because the center of the highway is higher to promote drainage of water down at the sides. In the US we ride on the right side of the road, therefore the crown is to our left, and is the highest point on the road and causes in-even wear. If we lived in Europe and rode on the left side of the road, well then, there would be greater wear on the right side of the front tire instead!.
Here's the link and a diagram: https://www.quora.com/Why-do-my-motorcycle-tires-have-uneven-wear
After 8 thousand miles in the past 2 years, it's why I need a new front time!
On that site I see turns mentioned as the cause, I see road crown mentioned as the cause, I see wedging mentioned as the cause, I see rim alignment mentioned as the cause but no data, testing, or explanation proving that any one of those are the actual cause of L/H side motorcycle wear.
I guess common sense makes me ask how a typical U.S. road crown of 1°-2° can cause front tire wear that is 10°+ off center?
How can road crown wear a tire that far off center on a single track vehicle?
Again, lean the bike over until the part of the tire that is wearing is flat on the pavement, that is how the bike was ridden to cause the wear in that area.
Even leaning the bike over until the tire wear area is on the pavement on a 2° crowned road will show normal riding on that crowned road won’t get it anywhere near the tire wear spot shown in the OP’s post above.
