I was always told that there were two things the Americans could just never get the hang of; building cars that went round corners quickly and building motorbikes that went round corners quickly.
"They don't have enough corners" my Dad would say, "only straight roads. They only need to go quick in a straight line. That's why they have horrible soft suspension and huge, petrol-eating, low revving engines."
And, to this day, with the possible exception of the new Ford GT, I have no reason to refute my Father's imparted wisdom.
But then, cornering speed isn't everything. And when a bike looks like these two do, you can forgive them a few things.
