Another wrist-pain sufferer here, looking for relief. I've gotten control of my body position for the most part, relying more on my lower back muscles to keep my weight off the wrists, and that's helped some. Plus, I just test rode an R6 the other day and had no pain at all, so I'm tentatively ruling out body-position as the culprit.
I tried out a crampbuster for the past few weeks. That's helped some on the slab, but the thing moves around alot and tends to get in the way around town. I'm ordering a set of grip puppies, and have some hope that those will help, too.
Is there any way to install weaker throttle / return springs? I have it in my head that the grip is just too difficult to twist/hold.
