welcome to the motorcycling world!
Here most of the cage-driving philosophy does not apply, especially offroad.
As Frank sayed, in motorcycling world it's 90% about the rider, it's experience that counts.
First I recommend doing a bike courses and lessons, ride at least one season with a less powerful lightweight bike, i.e. Suzuki DRZ400 as you mentioned - easier to dig it out once you're bed in and much better/safer to learn on. Taking a big powerful bike without having no experiences with motorcycles as a noob can badly hurt or even be fatal, especially offroad, so start it slow and invest more into riding equipment first, a protective equipment has higher priority for any newbie than a bike itself IMHO - better buy a cheap s/h bike and get a quality riding equipment than vice versa if your budget is limited.
But the question is if you want to ride the bike to the place or rent the bike there on the spot? If riding there then things turn out completely different, you'll spend most of the time riding there and then you need a long distance capable bike which usually means it's more powerful, comfortible, bigger fuel tank, heavier and thus has less offroad capability. There's no ideal bike for on&offroad both, everyting is compromised, but as sayed before it's also mostly up to the rider.
Let us know if you ride there from Europe or buy/rent the bike on the spot, then people here can give you much more detailed advice.
