I will be 65 on my next birthday. Fortunately I'm in good health overall and plan to ride until I fall off more than I stay on. I have ridden an 02' GS for the last 10 years and really love the bike, though most of my riding is two up and on the highway, not exactly what the bike was built for. Unfortunately I have not had the opportunity to ride many other BMW's. I have put some miles on 1200 RT as well as newer GS's, but never a K bike for instance. Is my GS the right bike to ride into the sunset or should I consider others as I grow older and less limber? I'm not sure I want to spend the money on a new 1600, but it is not out of the question.....nor is another brand. I'm curious as to how other aging riders have chosen the right bike. We do like to ride long distances, so comfort and carrying capacity are a consideration. All suggestions would be greatly appreciated.
