I saw the "Zero" electric motorcycles at a dealer in Texas, a couple of years ago. Neat idea. At the time, they were made in the USA. Their website says "Crafted in California"
They also had some electric scooters that were similar to the little 49cc scooters. Don't know where they were manufactured, but the salesman told me that they were good sellers.
The idea that Yamaha may be marketing electirc motorcycle(s) sorta makes ya wonder.
I mean, ten years ago if you had told me that a car like the Prius would be selling like hotcakes, I'd of thought you were nuts. They're everywhere now.
Electric motorcycles? Eh, maybe. Seems like they'd make good comuter bikes.
