Per the official TTXGP blog post seen here, the winning bike from the TTXGP race will spawn a production electric motorcycle, the Mavizen TTX02. 

"On November/3rd, 2009 at 1305Hrs PST, the world's first supersport bike bred on the Isle of Man TTXGP will be launched in Las Vegas at the SEMA Show."

It seems that EV product developers are learning fast to generate excitement for EV's through racing competitions, and using the best in class performers as the prototypes for production vehicles.  Funny that Killacycle and some of the other world record holding electric drag racers haven't evolved into products, but I suppose a new tech needs to demonstrate itself in endurance ralleys before it is truly proven.
