Congratulations! you've just opened your self up to a whole new realm of riding opportunities. If I may suggest a few things, install crash bars and skid plate, get some good maps of the area you plan to visit ( don't rely on GPS), usually you can find some friendly locals to help confirm a destination if your polite. buy the best and lightest camping equipment you can afford, doesn't have to be new. I tend to look for higher end backpacking stuff. focus on a good sleep system, if your going to invest, invest in a good mattress and sleeping bag. A good night's sleep is key to having a good trip IMHO.
Practice a lot of low speed maneuvers, practice standing up doing said maneuvers.
Learn to patch and plug a tire and carry the equipment needed to do the job on the trail. I think this is probably the most likely breakdown a rider will encounter, a pump and some tire plugs could save a long walk.
And most important, pick your riding partners well, knowing that you are riding with somebody that is prepared and has your back makes all the difference. Be prepared yourself so you can be the same.
ENJOY THE JOURNEY!!!
