Would you ever ride a motorbike with no handlebars? Yamaha think you might!
What will human–machine interfaces actually be like in the future? Apparently this is the question that Yamaha were attempting to answer when they came up with Motoroid 2. That of the self-balancing electric motorbike. 
In the case of the Motoroid 2, this means a chassis that allows the rear half to tilt, the front thereby 'steering itself' - hence the handlebarless design. 
Yamaha are also talking about the Motoroid 2 as a vehicle that, "can recognise its owner, get up off its kickstand, and move alongside its rider, but also has a distinctly lifelike feel when somebody is riding on its back and has a presence more like a lifetime companion."
