Makes me wish we could buy stuff like the Westfield XTR over here in the States. With a Hayabusa motor and modified gearing it should be able to pull very high mpg numbers. This stuff makes my <1 ton Spyder look like a truck.
I bet that car isn't a slouch either, the redline is over 10k!
Wonder what that donor bike was, I'm no bike expert but the gauges look Honda based on the motorcycle videos I've watched.
