Just to be sure I knew hybrids were in their future thinking, Yamaha also has this HV-01 hybrid scooter.
From Yamaha:
This is a parallel hybrid scooter mounting an electric motor and gasoline engine. Despite the large body that gives a feeling of spacious comfort to the ride, this model has torque-y power development in the low rpm range that delivers the acceleration feeling of a bike one class above, as well as good fuel economy, environmental friendliness and performance that brings a real joy of riding. At the same time it has convenient functions that only hybrid bike offer, such as a “quiet mode” (running only on the electric motor) and a “push mode” that makes pushing the bike in places like parking lots (super low-power drive when off the bike).
