I found someone, with LOTS of experience, to ride mine back when I bought it. He has been riding for 20 years or more and owns his own bike. So I knew that I could trust him.
I then played around in a parking lot and rural areas until I was comfortable with it.
Maybe ask the dealer if they can deliver it? (If it's not too far, then it's their responsibility until it's in your driveway.) Better to do that and be honest that you aren't comfortable riding in busy areas yet. Rather then acting like a pro but really you're nervous as hell when you try to drive away with it. (That's just my take on it, people respect honesty.)
