I agree on the backpack until I bought motorcycle specific backpack. I got a kreiga and I'm considering taking it hiking instead of my normal pack ; its that comfortable.This is an old thread resurrected but my 2 cents may be useful. I did 800 miles last year and it was not pretty. A good 30 pounds on my back. Wind noise a constant distraction running 80-90mphs. Mind you, the ride up wasn't all that bad. The ride home was not pleasant. Ear plugs would have gone a long way to aiding and abetting the stupidity of doing such a long ride. I had to stop every hour without exception. The pain of carrying a heavy back pack took it's toll. I was beat to shit once I got home and will never do a long distance ride ever again on this bike.
Being physically able to do it is one thing. I can say that I did it. But this bike is not the tool of choice...not by a long shot.
It's a wonderful motorcycle and I will say that without reservation. But long distance? This is not the tool for doing it. I can point to my experience and simply say that I did it and "survived". Just having survived is not something you want to notch on your "experience" belt.
Earplugs aren't just for the exhaust noise - the issue is the wind noise. At highway speeds it's significant.I live in Sudbury Canada. I drove from here to Halifax, then to Boston, then home, for a distance of over 4000km. What made it a good ride was that I too breaks as needed. I never passed a rest spot. I have stock exhaust on mine and I didn't need ear plugs..
