Yeah, my right hand is getting numb after just short rides lately. Which is kinda weird because I did around 5k miles and was never bothered by it until recently. I was thinking maybe because I wear a backpack that the extra weight pulling on my shoulders/back might have had something to do with it but that's not the case. It's not bad enough to make me give up riding the Busa, but it can get pretty annoying. I am using Helibars and the BMW Sportgrips... No cramping and no death gripping... just numbness.
