Not so long ago we showed you an absolutely wicked 4-wheel motorcycle, theYamaha Tesseract (hit that link if you haven't seen it, trust us). Now the design is looking to be a trend with this recent unveiling of Sbarro's Pendolauto at theGeneva Motor Show. Adding a bit of stability to the standard crotch rocket, but still lean-turning like a motorcycle, it's too bad that America will absolutely never let these vehicles on our streets. Hmm...where could they fit the airbag? [gizmodo.com]
