Numb hands

MDU, I expected better than you being a thread dredger

Other than the cold or vibration you can get position numbness... as a cyclist and I'm guessing on a motorbike too, if you keep your wrists bent then you can pinch the blood vessels runing through your wrists. Just my 2 cents worth but it did make a difference on longer rides.
