The reason why I selected the cylinder head cover on the OP webpage was because it does have a lot of venting space for air to go through.
No matter how you look at it, if you cover a cylinder head with material you are blocking air flow.
But it isn't the cylinder head, it is merely a cam cover

I know some are gonna jump up and say: "it aint so". But will you have empirical data to show that the cover does not cause the fan to trigger sooner on a given hot day, or at a light?
I haven't, BUT BMW do. They make them, they test them, they are prepared to warranty the bike with them for EVERY country the bike is sold to (hot or cold countries).
It REALLY isn't an issue.

I am currently driving a friend's RT with a BMW cover. Its been rather cool around here, and I noticed the fans kick in at a light when it 'appears' to me they should not. I could be wrong about this.
I think you are. The thermal management on these bikes are designed to heat up REALLY quickly and the thermal management is aided at low speed, by the fan. It doesn't mean there is a problem, it means the bike is at the correct cooking temperature for optimal use.

Well, that's a bit mean. But I do think you are looking for a problem where there ISN'T one.
If you fit a guard then you may as well make it one that works the best it can for a given design. And the BMW one does just that.
