I'm not convinced. Here's why.
1. What sort of engine has it got? Unless it's actually using a small aerojet, to get anything capable of producing that much bhp in something that size would be very difficult. There'd be huge cooling issues, not to mention huge amounts of fuel needed. And exhaust space. And so on. And a 50-gallon trunk space? Where?
2. The Swiss road laws are so restrictive that even underpowerd H-Ds have to be built in specially restricted versions for the Swiss market and forced to crawl along at speeds where it's hard even to stay upright. This thing would never make it onto a Swiss road - not legally, anyway.
3. It bears a more than passing resemblance to something very similar built several years ago called an Oekomobile, if I remember, which was basically a BMW K100 with a bodyshell like this one. From the swingarm out the back of this one it seems similar but with maybe something like a ZZR driving it. Which leads to
4. How much horsepower do you think you could get down through a rear wheel like that? 200, tops, right?
