There are two possibilities: 1. You're putting too much weight on your hands.
2. The grip is the wrong diameter or softness for your hands.
1. Most riders place too much weight on their hands when switching to a more sportier bike. I'm not sure how the 599 compares in ergonomics, but I'm sure it's a bit more upright than a stock VFR. Try consciously riding without putting any weight on your hands arms and see if that helps. To do so, put your knees up against the tank, press your lower back forward, straighten your upper back, tuck your elbows in, and relax. Loosey goosey on your arms. Helibars, convertibars, genmar risers, rogue's riser, etc. may help as well.
You can try different grips if that doesn't work, but you should be able to tell where the problem is coming from if you think about it.
Do you have a death grip on the grips, too much tension in the wrists, pins and needles in the hand, too much vibration, etc? Isolating what is causing your discomfort will go a long way in fixing it.
For sure, the 599 is more upright than VFR. I did try sitting upright as you describe, and that does take some weight off my hands. But I can't stay that way -- I need to maintain a good grip on the bars. Your thoughts on isolation are good -- I did wonder first if I was gripping too tightly. I've wondered that on my 599, and that led to thinking that my (earlier) gloves were just not sized well -- perhaps the leather in the fingers didn't "give" well enough when I gripped something tightly, restricting circulation. This idea makes me want to try the textile gloves. With that in mind, I consciously loosened up my grip on the bars... no real change overall, however.
The sensation I have is just a soreness/tiredness. There's not a pins-and-needles sensation, and my wrists don't hurt. (Honestly, I had a fear to begin with that my wrists would suffer -- not my hands.)
Vibration came to mind, simply in that I knew the VFR I rode back in June was equipped with anti-vibe bar ends. I had nothing to compare it to, though, and it's not available to me now for comparison, so there may or may not be any merit in my thinking that.
The diameter of the grip did come to mind. I haven't yet whipped out the calipers and compared VFR grip diameter to 599 grip diameter, but that will get done shortly. As for the Heli-bars, that's a mod I considered before even buying this bike. I suspect those will be on my "Santa list" this year, but I want to be able to ride comfortably until then.
I wonder, too, about the angle of the grip.

I've ripped off a hand photo from someone's web site and added a couple of lines. The red line [very] roughly indicates the contact between my hand and the bike's grip (and my present soreness). The blue line is more in line with the natural line of the closed hand. Does this mean anything? I'm not sure. (But they say a pic is worth a thousand words, so I felt I had to offer one. :) )
Spider grips? I'll have to surf that out. Monk's signature mentions Grip Puppies -- those are very affordable! Wonder if I've got a local supplier....
Gotta get my laundry and some garage work done... then I'm going riding! :)
