BMW Z21 “Just 4/2” (1995)
Concept BMW Z21 – the public saw at the Tokyo Motor Show in 1995. It performed not under a boring serial number, but under the stage name Just 4/2. From the name you can understand that its “just for two”.
In fact – a motorcycle, just on four wheels, and the riders sit side by side, and not one behind the other. There is no roof or windshield. The motor is a motorcycle (from the BMW K100). It accelerates a 550-kilogram roadster to a hundred in less than six seconds.
