Where the automotive market goes, the motorcycle market soon follows. It was only a matter of time before electrified power trains made their way into two wheels. There have, of course, been electric motorcycles for years, but back when battery technology was more primitive. They never really threatened the dominant gasoline-powered bikes on the market. Nowadays that's becoming less true. Electric motorcycles like the Zero SR/S can wave their spec sheet in the faces of gas-powered competition without shame.
