One of the most eye catching bike in Tokyo Motor Show 2007 might be this one, Yamaha Tesseract. It doesn't like common motorcycle which only have two wheel, it have four wheels. Unfortunately, you look for it in Yamaha dealer for recent time. It’s just a styling concept and have not mass produced. Y
It’s not technically a motorcycle, and “Tesseract” sounds like something Scooby-Doo would say, but who cares? It looks incredible and has enough techno-jewelry to make the most jaded gearhead drool. Mounted in that spidery chassis is a V-Twin motor that’s the basis for a hybrid propulsion unit. Front suspension is something Yamaha calls “dual scythe,” and like the Piaggio MP3, the wheels lean with the chassis into the turns to impart that authentic motorcycle-riding feel. Like the Piaggio, the frontal profile is almost as narrow as a motorcycle, which would make this a fun and interesting street ride. The extra wheel will add stability, for sure, but also make this as likely to become DOT-legal as a Tiger tank.
