Get a can of ACF-50 and spray the bike down. This is an Anti-Corrosion Fluid and will go a lo way in preventing corrosion developing on your bike. You don't need to overdo it, just a light coat all over. Up around the tank mounting bolts and other through bolts on the frame and the wheels seem to be the worst spots. But the bike will definitely show some corrosion if you don't take care of it.
