Lemon law is based upon where you registered the bike, not where you bought it.
If you haven't personally engaged with Ducati North America yet, I would suggest you do so. I don't mean through the dealership, call them directly, leave a message, tell them you're not happy and explain why. I can't promise you they will make it right to your satisfaction, but they do care about stuff like this. If all your communications are going through the dealer, though, it's unlikely that DNA knows you are upset. I dealt with a similar situation earlier this year and once I made that phone call, things started to happen.
