I love ADV riding and if I could only have one bike it would be an ADV of some sort. I have a Tiger 800XC and added a Rocket a couple months ago. If you just want to explore some fire roads, do some overnight campouts, etc, the KTM is overkill for your first ADV bike. You will drop it and beat it up, nature of the sport. Not to mention that the 1290 is a tall, heavy bike. I'd start with something smaller and much less expensive for your first ADV. Keep the Rocket and try a DR650 or KLR and see how much you enjoy the sport would be my advice. The price of either, used, won't break you. ADV bikes aren't like street bikes, there is a lot more differentiation between them, and too much weight or power, first time out especially, can get you in a lot of trouble.
