CRP - the Italian race bike manufacturer that's been doing electric racing the last two years - they have unveiled their "Next Gen Electric Superbike" that they've been teasing us with on Twitter for several months. It's a 100% electric superbike - 130+ miles/hr - 93 miles range - AC motor
I believe 2nd from left is probably Shelina Moreda, an American born racer who began racing with CRP at the Laguna Seca race last summer.

I was most interested by the motor. They describe it as "PMAC Synchronous Motor, Permanent Magnets" .. took a small bit of sleuthing but the wikipedia (
http://en.wikipedia.org/wiki/Synchronous_motor) is helpful.
Synchronous motors are a type of AC motor where the RPM/speed is directly determined by the input frequency of the power source. The wikipedia says they are used in instances where a fixed RPM is required. Which isn't the situation you can have on a motorcycle, right? It must be that their controller has a variable frequency.
