I did a quick search and this didn't come up. I was reading some stuff on the Isle of Man and this year was a the first year with a Zero's race which features fully electric motorcycles in a 1 lap sprint. The winner of this year's bike is quite a feat of engineering with hotswappable lithium batteries and a top speed of 140+ mph and a great time around the track. Here's the jump to where I stumbled on this. The World’s Most Advanced Electric Motorcycle Here's an article on it and a short clip from the race. MotoCzysz news_view Pretty cool stuff I must say. Makes me really want a bike more than ever now haha.
There is also the Brammo. They have a model you may be able to buy soon, ~$8K, at Best Buy in WA and OR, .
I missed Isle of Man this year, but the electric bikes are awesome. 140+ MPH? That's about the speed of a 600cc superbike, and probably lighter to boot.
