I've had a "bad shoulder" for the past 2 years, now diagnosed as rotator cuff injury. I realised i probably got this injury from riding my motorcycle (Kawasaki 250cc KLX) on a few long 350+ km rides over a few day holiday. Perhaps the constant and repetitive stress on my right shoulder from riding led to this injury? Does anyone else have a similar shoulder problem from from riding, and if so, how did you fix the problem. It is nagging and bothers me every time I ride for more than 15 minutes. I'd prefer not to give up riding, or have surgery.
