Crap, isn't it. Very hard to prevent too, plastic wraps can fix it... WD40's overrated for this sort of thing, it's a very light oil and washes off too easily, but even ACF50 or FS365 isn't foolproof. But the best thing to do is to do what Suzuki should have done in the first place and powdercoat them, it's a bit of a hassle to do but not expensive (mine were £20 the pair in black) Or, warranty claim, you don't need to say "never seen salt" since it's a bike, not an ornament. But I'm not sure how likely that is to work.
