There is no cure for that, this is what tires inherently do. In the USA the left hand turn is always longer, the crown of the road is always on the right side of the tire, so the left side simply wears faster and all tires eventually cup.
I honestly do not know of any cure for it, it is just what tires do.
The 1800 is my bike. The very best motorcycle ever made. I was enthralled with my first test ride on this machine. It is a great bike.
