This is an April Fool's joke, notice they're basically talking about powerless powered vehicles. Kind of like perpetual motion machines. Good one. You fooled a few.
The giveaway is this sentence "The development of completely noiseless ORVs with zero emissions of any type, zero sound of any type, and zero fuel consumption." The idea this sentence allows KTM's zero-emission bike fails because it requires electricity for it's recharging and there is no mention from KTM that it emits zero sound. "Zero sound of any type" can't allow the sound of wheel's turning, braking, etc. The other giveaway was the date, April 1st, 2009.
Hey for those in Australia or Canada, do they have an April 1st there? (if you answer "no", the reply question is "oh, so April starts on the 2nd there?" [grin])
