Yamaha sells a model called the Tricker in Japan which has a 249cc four-stroke single mounted in a chassis resembling that of a trick BMW bicycle. The current production model is similar to the models shown on this page and the next, but the components on these specials are obviously a lot more exotic.
The current production Tricker weighs in at 110kg while this special 'Air Tricker' weighs in at 90kg thanks partly to a sculpted carbon frame.

Edit: много мерси на едно Лице за това чудо на чудесата...
