Gizmag does the 4mc test ride and reports that this crazy contraption has much to offer the traditional two wheel motorcyclist. The short answer is that it has a ton to offer, as in, nearly impossible to lose traction and wipe out. The four tires offer a crazy amount of contact patch with the road and the mechanical system makes it full leanable even at a standstill without falling over.
It is a pretty amazing machine and I'd love to check it out first hand by giving it a test ride. It could very well change the face of motorcycling and make it way safer. The other interesting bit in the story is that it is classified as a trike (despite the clearly visible fourth wheel) which opens it up to operation by people with regular car licenses.
Now imagine this motorcycle with a big old screamer engine like a Hayabusa or V-Max in it! It could cook like nobody's business! Coolness indeed!
