I too went for the Yamaha ones and fitted the extra spoilers (was I the only one confused by the instructions?!!).

I have to say that I'm a little disappointed with the amount of protection from the wind/elements provided by these but the build is pretty good.
8/10 for build
6/10 for protection

At this price (�60 - �80) I'd shop around if weather protection is foremost in your mind.
