Looking for advice. I have an 09 GSA for long haul touring, pavement. It's great for heavy loads over long paved rides. Now I keep reading about guys like Colebach, etc who ride gravel and dirt and sand and off road, places where the big pig is a handful, like all the way to Magadan and Mongolia I want to explore the rougher ride, and wanted advice on what bike might work, maybe with soft luggage for some real adventure riding, including lots of fire roads, gravel and dirt, while still carrying lightweight camping gear. I have seen some pics of the BMW 650X Challenge and its looks good. Is this a good place to start my off pavement exploration, or do I need to go lighter. I have zero off road time, and don't mind taking some training programs. All information appreciated.
