My reading of the warranty and other literature is that having the maintenance done by a dealer is merely recommended and not required and I do everything myself. Mind you I have not had any occasion to make a warranty claim on either of our F650GS bikes (2010 &2011). I keep all receipts for parts and oil and I record the maintenance on the same form that the dealers use. Of course some a-hole could give you a hard time over doing it yourself. What you decide is a function of your confidence in your own abilities and how risk averse you are. I did invest in a GS-911 and it's great to have.
