Riding in wind

[MidLife]

One factor I'm missing: lift...

Sorry you missed the lift factor, but of course it is in there:



Cs (Side Force) and CL (Lift) factors are compared in this table:





Showing that Lift is relatively small vs Side Force.

However, also noted,



Hence, although smaller than side force, there is a very large lift variation between 30 and 60 deg (10 times larger at 60 deg) which is what will be felt when hit by a sudden side gust.

As pointed by @Daboo, here again, forward speed (smaller angle) is your friend.

What I've never figured out is why on a trip, I fight a headwind heading to the destination, and then a headwind going home. Why do I never seem to get a tailwind both ways?

Methinks lift should have received more attention/given more weight in this; especially on full faired motorcycles...
Many design elements seek to increase downforces at speed, even adding Canards... obviously for a reason...

As also documented in the paper, the simulation is for a fully faired R1.

Same proven simulation models that are used for race cars design. The results are what they are, not sure how you can arbitrarily decide to weight them other than presented.

Absolutely, and these same simulation models are what is used to predict the down forces and drag of these elements.
