Much has been written/asked about numb hands, and how to fix the problem. Many have suggested the simply gripping too hard with the right hand may contribute to the problem. I think it does.
Yesterday, purely by accident, I stumbled on something that helped my problem.
Many of you old timers may know this, but I didn't, and I, like, ain't young.
With the new RT, I have been consciously trying to place my hands as close as possible to the inner ring on the grips so as to have my fingers closer to the control buttons.
Yesterday, I let my hand natually drift out a bit (perhaps I am finally beginning to relax??), and found that, with my glove resting on the unmoveable bar end and on the throttle, it was much easier to maintain throttle position with a lighter grip. Sort of like a mini cruise controlled comprised of one ham-handed leather glove. It made life easier.
