As Mike noted - speed kills mileage.
For most vehicles, 45 MPH is where mileage peaks - and it's all downhill from there.
Slowing down is the easiest way to improve mileage as long as you are at a safe speed.
A larger windscreen may help mileage also. It's probably more frontal area, but directs the air over your helmet and shoulders better.
As also noted, there is a point at high speeds where too tall of gearing will drop the RPMs to a point where less power is available, and top speed in top gear may be reduced.
EDIT: Knowing your engine's torque peak RPM can also be beneficial when modding for mileage. Cruising at the torque peak puts the engine in its most efficient range normally. You need to balance that with the lowest RPMs and minimal throttle opening.
