According to Yamaha it is a 4 wheel 2 engine vehicle that to me looks cool as all get-out.  Just like my mountain bike, it don't need no stinking kick-stand!

Reminds me of the new scooter from Piaggio (manufacturer of the Vespa):



Although the Yamaha looks cooler.

Now that is freakin' awesome! Do the wheels tilt and all?

•Tesseract (Special exhibition model / prototype)
This is a hybrid 4-wheeled vehicle powered by a combination of a liquid-cooled V-twin gasoline engine and an electric motor. It is also designed with a unique dual-scythe suspension that enables cornering with a lean (banking) like a motorcycle despite the 4-wheel format. There is also a dual arm-lock system that keeps the machine upright when at rest without a stand. It offers excellent performance and maneuverability with a machine width roughly equivalent to that of a 2-wheeler.

the Piaggio leans, too.

Tessaracts give me headaches, and I don't get them...

How about a 500 Horsepower V-10 BIKE:
In theory, 400 MILES PER HOUR

Sorry, not remotely possible with that frontal area and drag coefficient, even with 500 HP.

Apparently the demonstration rider had a very difficult time controlling it even at low speeds let alone 400 mph!!

[Bob in St. Louis]

True, but we're talking "theory" which is the way an engineers would say, "It's all a big fantasy...paid for on the companies credit card". Right? 

Besides, it's just FUN to say, "400mph, with 500HP". I don't get to say that very often.  aa

I heard of these.  My brother in law is a big motorcycle fan and he told me about it.  Apparently intended to assist in high speed cornering, as if we need any assistance in killing ourselves with speed.

(still OT) how about "Stranger in a Strange Land"  by Heinlein. Great premise for the social commentary that it is.

[DeeCee]

(Continuing OT) I hope folks will read Starship Troopers before seeing the movie (then follow it with Joe Haldeman's Forever War... now THAT's a killer book! - uh, so to speak)
