Bikes are pretty sensitive to wind/air resistance too, as they are not very aerodynamic. The open shape of a motorcycle, with added rider, is more of a sail than anything else and only gets worse as speed increases.
Headwinds and tailwinds can have noticeable effects on both speed and fuel economy as well.
I have an instant fuel use gauge on the ZX14 and it is really surprising how much better the bike is on fuel fully tucked rather than riding in normal riding position. Goes from 6.5l/100km to about 5.8 or so when you duck behind the screen at highway speeds.
