Unlike most major auto shows, Tokyo devotes a significant amount of exhibition space to motorcycles. Among the two-wheeled production bikes, a number of concepts demonstrate the future of motorcycles, from Akira-worthy superbikes to fuel-cell scooters.
As a large part of cornering on a motorcycle involves leaning over, a four-wheeled motorcycle would seem impossible. But Yamaha seems to have gotten a handle on this idea with the Tesseract concept, which uses a double scythe suspension that lets the twin motorcycle frames lean to either side.
Yamaha designed the Tesseract with a hybrid power system, just in case you think a conventional motorcycle engine uses too much gas. The Tesseract would combine a V-twin gas engine with an electric motor.
Yamaha's Luxair concept enters Akira territory with tons of tech. Its hybrid powertrain uses an electric motor for extra boost and as a reverse gear. Yamaha equipped it with the Natural Sound Motorcycle Audio System, which can send audio to the rider's helmet via Bluetooth.
As the name implies, Suzuki designed the Biplane to capture the feeling of flying an airplane. The concept is sure to get plenty of lift from its 1,000cc V-4. Just hope you don't actually leave the ground.
Yamaha explores a practical fuel-cell design for a scooter with the FC-Dii. Its fuel cell uses methanol to generate electricity, which can then be stored in its lithium-ion battery. That battery can also be taken out and recharged.
