How about a direct injection 250 2 stroke going flat stick generating power for an electric motor, I don't know if you would get enough kilowatts to the motor, and it would be against the Zero emissions rules. Under the current regs as they stand we wouldn't even be able to use hydrogen fuel cell because it emits water.get rid of all those nasty heavy batteries,can't deny that, they are heavy (and expensive). Our bike is about 100kg heavier than a superbike no gearbox we don't have a need for a gearbox (the "map" I posted will show why)or bogging down off the powerthey don't come off the power band and bog down in the way we all understand it, and I think we were about 123mph over the finish line speed trap from a standing start, over to you Mr Mugen
