Gidday mate, congrats on a superb looking bike - rather like mine . . . except yours has a taller screen. Put the quick shifter on it, they're awesome. Anycase there's miles of smiles coming your way as soon as you ride it!
Congrats on the new to you wheels and welcome to the forum from sunny (usually) North Texas. The best way to keep aluminum from corroding is to keep it dry. You can always apply a wax or sealer, but it may not look as good.
