Zeeede, here is just a suggestion. Some gravel, some smooth twisties, some sharp twisties, some old dirt roads, and one short leg of a class VI road. But, people have done all these on a 1200GS, so just take your time. Mackey Rd and Hale Hill Rd in Troy are Class VI - read trail - but dry this time of year. Guys from Boston did it on big GS bikes, and I ride it with Anakees on my 650. Switch off your ABS on the loose rock and sand As always, you get in trouble, you are on your own. Use the route on your own risk, et cetera.
