The weights would be called "bob weights" by engineers concerned with
reducing the vibration transmitted to the handlebar.
The heavier the bob weight, the lower the frequency of vibration.
The weights used by Kawasaki are rather small, the handlebars are short, and
they appear to be rigidly mounted to the upper triple clamp.
Were Kawasaki engineers even *trying* to reduce vibration?
My Yamaha has rubber mounted handlebar clamps and much larger bob weights,
but there is still a vibration at about 4500 RPM, which is typical of 1000cc
I-4's.
The pistons move up and down rapidly toward the handlebars and back and I get
the vibration.

You might try a gel grip. The ideal gel grip would have a barrel shape to fit
the hollow of the palm of your hand.
A company named FinQ used to make natural rubber grips with the barrel shape.
I appreciated them because I injured my throttle hand on my very first
motorcycle ride and it cramps very easily.
When I raced Moto-X, I injured my hand again by hitting somebody else's
handlebar with my throttle hand.
For the next few years I taped the twist grip until it was about 2 inches in
diameter so I could hold it without getting cramps.
Nobody had ever heard of carpal tunnel syndrome, we just knew that our
throttle hands and wrists hurt like hell.

To (relatively) cheap things to try:
Slip-on foam grips. Gives a slight cushion and different geometry. Less
than $10, if you can find the right size.
Heavier bar-end weights.

Hold the 'bars less tight, this improves handling and helps stop the effects
of the vibration getting thru.
It make even reduce the actual vibration by changing the natural frequency
of the 'bar/hand combination.
Get the carb balance checked as this will help the engine run smoother.
Check the front wheel balance too while you're at it.

Got 'em on my K11LT... One word of warning... When coupled with heated
hand grips you've *GOTTA* monitor the tightness when the grips are on...
After cruising for a couple hours with the grips on the Throttlemeister can
become so tight that you won't be able to loosen it and might not be able
to roll off the throttle...
