I just looked at the Suzuki web page and you must be buying the Adventure model that has the luggage as standard. I didn't know they offered this option on the 1000.
I really doubt the dealer is going to sell the bike without the luggage, if he does, he will have to credit you and then try to sell it himself, too much hassle.
I'm sure you know this but Suzuki does offer the bike without the luggage, although it looks like only in red, not the black that I presume you want. Kinda lame on their part if you ask me.
