Remember, doing it yourself doesn't always mean you're making something look nicer. Sometimes you turn a perfectly good Honda motorcycle into a recumbent spearmint pod. It's worth it, though, when that pod gets 91km/L going nearly 90km/h.
Allert Jacobs designed and built this contraption from a Honda Innova motorcycle. In its previous incarnation, the bike weighed 105kg and got 48km/L.
By giving it an aerodynamic shell (that splits in half for easy entry), Jacobs has undoubtedly made his hog a much more efficient vehicle in all aspects, aside picking up ladies or applying to the Hell's Angels. [Allert Jacobs via Inhabitat]
