I know that the original poster seemed to have had enough of suggestions but this may serve as an exercise for the rest of us. With stock gearing we know what it means to have slowed down to first in a tight bumpy corner and try to get out of the hole again.
Other than the general tuning characteristics of the engine, could flywheel effect be part of this? I know my little 20 year old 600 4cyl can out pull the rc from 1500-2500 and even though it has a higher redline it just feels uncomfortable running high.
So maybe it is rotational inertia that beats the erratic speeding and slowing of the crank at low rpm and can smooth it out, but with the ill effects of resisting to go to high rpm. I wonder if anyone has ever altered the flywheel to positive or negative direction and can comment on the difference.

You are correct.
the varadero had a heavier flywheel fitted than the firestorm because honda knew that the vara would normally be ridden at a more sedate pace.
My varadero, pre mods. was very smooth way down to 1500RPM. But it was a bitch when the tps was not set right.
