View Full Version : 4-Wheel motorcycle

Take a gander at this!



The Tomahawk Concept
This is the wild one. Imagine a 500-horsepower Viper engine on wheels. No chassis or body, just wheels. That’s the Tomahawk. Wolfgang Bernard, outfitted in the requisite leather jacket, drove this concept onstage.

This 4-wheel motorbike is a mechanical sculpture, with nothing but outrageous performance in mind. Weighing only 1,500 lbs., the Tomahawk can reach 60 mph in just 2.5 seconds. Top speed is estimated to be around 300 mph, but that hasn’t been verified. Yet. When Dieter Zetsche, president and CEO of the Chrysler Group asked if this vehicle would ever be produced, the response was “maybe,” which is more than many other automaker execs would have granted.

It may even be close to self-balancing. Back in the '60's an uncle of mine did something like this with a chevy V-8 underslung from big diameter aircraft wheels.

The problem was holding it upright against the torque while revving. . .

Went up to a Gold-Wing the other day, because it was sounding like a Harley, and I wanted to know why...

It's own idle was so quiet, I wasn't even hearing it.

BUT it did have a big stereo, on which the guy was playing a tape he'd made of an idling Harley...

Jeeze, that thing's incredibly beefy! I've ridden a new GSXR1000 and it's plain scary...wheelies on demand with just a crack of the throttle. I can't even imagine how dangerous this monster bike thing would be! :eek:

Tim the Toolman has apparently taken up motorcycles as a hobby ... ;)

Geez if it's speed they want why not just ditch the motor all together and strap a couple of JATO bottles to the frame! Rocket sled on wheels! ;)

Of course Mr. Leno's bike is only 300 hp.
It's a bit more compact though since it's run by a jet engine.

I wonder if there's an odd "bump" as you go from leaning one way to the other, like when changing lanes... :confused:

Cool thought, from a company who's come up with some great concepts over the last decade.

I really DON'T want to try to ride that thing down a twisty road. It looks to me like something built mainly to be impressive on the stage, and it does that very well indeed. Give me my old Ducati any day.

Pine box, eh? Well, I did fill out an organ donor card when I bought a motorcycle, and that was just a stock Kawasaki...

OK, trivia question: which of the E. E. "Doc" Smith books is it that the hero zooms out of his garage on one of these, with flashing purple lights and a siren?

You can have your Hayabusas. Personally, I'm more into this:

That's me crossing a 100' wide river during an off-road MC rally last summer. It's sort of boat-related, isn't it :D

Not seen to many off road Beemers. Does it have the horizontally opposed engine?

Nobody remember E J Potter the Michigan Mad Man?
Used to do demo rides on a 7.5 ltr Chevvie powered bike in the '60s on what passed for drag strips in England back then.

With a cross country on an X6, I think you qualified for "Iron Butt" a long time ago. tongue.gif :D
