Motorcycles are light, small, and easily able to ride up on sidewalks in search of hidden power plugs. They're the perfect electric vehicle but, despite a few notable exceptions
, they're still powered by dino juice. Yamaha, makers of the raucous crossplane crank R1 sportbike, has decided to go a little bit cuter for its vision of the rechargeable future, the EC-f. It features an aluminum frame, a lithium ion battery, and styling cues that will have riders worrying about that green ring turning red
. That, of course, assumes this will ever actually have riders, which is doubtful given the fate of most fanciful Tokyo Motor Show concepts like this.
