And here's a quick translated summary:

After a thousand leaks we finally get the latest work from Piaggio, even if for now it's just a prototype. It was designed to maximize security (specifically in downhill and wet conditions), it posseses the same capacity of manuverability as it's two-wheel cousins. This "thing" (not yet having a name), can handle like a normal bike thanks to it's particular leverage system that can make the two front wheels incline parallely.
The bike will handle better over bumpy roads with holes as weight is more evenly distributed. It's better on wet land because there is less likelyhood of a slide on three wheels.
The bike (or trike?) is available in both 250cc aswell as 500cc.
