I was in the same boat last October. Had ridden dirt bikes for years. Never even sat on a street bike until I owned this one and rode it off the lot. I was SCARED, mostly of making a fool of myself in front of the people at the dealership.
I took a MSF course beforehand, which prepared me a little bit. But even at that course, I got stuck on an enduro dirt bike.
But, it was fine. Took off from the dealer parking lot, made the right turn at the light with no problem, and been absolutely loving it ever since.
Just take it easy on throttle, braking, and turns until you learn the bikes capabilities as well as your own. One noob to another... [8D]
Definitely recommend the MSF course.
Oh, and remember to put the kick stand down before setting the bike down. That's been my only little mistake so far. Pulled up at a party, and found myself a nice spot on the side walk where nobody would run over it. Feeling like the biggest bad ass around, I kind of forgot what I was doing. Set the bike down without putting the kick stand down. 650 pounds is REALLY heavy when it's about half way over. Adrenaline kicked in and I managed to set it up again before anything touched the ground, that wasn't supposed to. Whew. That would have been really embarrassing.
Relax and enjoy. But keep your wits about you and respect the bike, and constantly have an "exit" plan for any possible situation that could come up on the road.
