Streamlined Honda 125cc motorbike: 214 mpg (US) @ 55 mph
 

This is a cross post from the Motorcycles subforum - it's such an awesome project I just wanted to post it in the Aero forum as well to make sure everyone sees it who is interested:

In a nutshell: 199 mpg (US) on his last 5 reported fill-ups, 2 of which were over 200 mpg. Cruising speed is typically 55 mph, in a mix of town & highway use, with some higher speeds as well.

It's a Honda 125cc single with fuel injection, revised (taller) gearing (sprocket swap), and a semi-automatic 4-speed transmission converted to full manual.

Two items of note about the builder, Allert Jacobs:

1) He's obviously no stranger to the topic of aerodynamics. He produces (commercially) human power velomobiles in the Netherlands, like this Quest recumbent trike:

2) He's an EM reader, and bought an MPGuino (not yet installed) to use in this project.
