I saw an olive and black Nightster today at the dealer and I'm totally in love with this bike! They said this one might be sold, but they could get me another.

My question is storage -- I know this isn't a touring bike but I would like to have some stuff with me on a day trip. I've got a tank bag for the small stuff. I wouldn't want to ruin the looks of the bike with something that doesn't suit it.

Any suggestions?
