It has also worked out fine for my dad (blue bike) even during a month long 7200 mile trip. If hard bags are your thing there are quite a few manufacturers with them but they tend to be spendy.
Don't forget a tank bag: there is not a speedo or anything dumb like that on the tank, and it makes a handy place for wet weather gear, money and camera.
Just don't get one that is too big: they bump against the starter switch in low speed turns!
