You're being a big wuss and clinging on for dear life! ;-) you could try adjusting your brake and clutch levers round the bars slightly to be in line with your forearms so you're not riding with bent wrists. Just loosen them off, rotate a bit tighten off and test. Make sure its all done up well and none of the brake and clutch lines are snagging or pulling when you rotate the bars from lock to lock.
Divvys all vibe at around 4000 rpm which can cause cramps and pins and needles in the hands and feet, so it might be this. Id relax more, but if it turns out to be vibe related, balancing carbs, replacing engine mount rubber can help. Heavier bar end weights can dull the vibe. It's a characteristic of this bike. Easiest solution is to use gears to stay out of that rev range. You know you're in it when your mirrors go ape**** and the coppers behind go blurry :-)
Good luck and Congrats on passing the DAS :-)
