Suzuki XF425 Ugly Duck

Two wheel drive motorcycles dominated the 1991 Tokyo Show. A number of prototypes were displayed by Honda and Suzuki whist Yamaha also showed an interest in this technology, though two-wheel steering.

Suzuki's prototypes were the XF5 and the "Ugly Duck". Whilst it looked like something from Toon Town, Japanese engineers strongly believed in the rideability of two-wheel drives. Being two-wheel drive it could easily replace off-road trikes.
