Try a tanker

I draft at a safe distance with tanker trucks. They seem to have a cleaner wake and you don't need to be as close to a 'van' box. It makes a big difference with my GL500.

skalding Basic Aerodynamics. In your case you were riding in the "wake" of the truck and thus had to expend less energy to push the air out of your way.

Here's a guy to took the design to it's logical end. http://ecomodder.com/blog/diy-aero-f...cycle-214-mpg/

I understand. I've seen folks in cages drafting semi's so close if the semi touched his brakes they were gonna make contact before the drafter could slow down. Had a guy in a pickup decapitate himself on the local Interstate a couple of years ago drafting a semi.

I kept two seconds following distance and was extremely alert for tire chunks and other things that might come my way. I felt it was better to be behind the truck where I could control the bike better than to have the wind push me into a cage. There is more maneuvering space on the Interstate (which is what I was traveling) than most other roads.

flitecontrol Discovered something on my recent ride to Missouri and back. I normally get around 48 mpg riding locally at speeds 55 and under. On the interstate, it goes down to as low as 35 mpg if I get above 75 mph.

There was a very stiff wind from the NW that was gusting so hard it would blow the bike all over the place. Noticed that when a semi passed me that the turbulence it created was much less than the wind buffeting, so I stayed in his wake until I had to exit for gas. Repeated the procedure until I got to my destination. When I was behind semi's, doing 70-75 mph, I was getting 50-52 mpg!

Anyone else had similar results?

Mostly city riding, and I like to put the "pedal to the metal" a lot.

Daytripper just did a check and I'm getting right at 47 mpg.
