Looks toasty.

How in heck does he steer the damn thing????.............

Exactly.

Brakes may be concealed between the rim and the wheel.

That’s a Continental IO-550-A. Horizontally opposed 6 cylinder. Made in Alabama.

It looks identical to the pristine engine in my good friend's immaculate Piper Comanche 260. I was trying to figure out why they keep calling it a “Continental Flat Six” manufactured by “Rolls Royce”. What kind of BS is that?

[dragnet2]

Looks like Mad Magazine material. What a joke.

Lean to the right, it will turn right.

Lean left, it will turn left.

I just realized, from a dynamic standpoint, it's ridiculous.

Look at the ground clearance, and the length of the wheelbase.

Every time you go over a bump, there's going to be significant up-and-down oscillation, From the picture, it looks like there's about a two-inch (or less) ground clearance under the driver, the driver and engine together probably mass about 600 pounds. The distance from the center of mass to the point of contact between the front wheel and the road looks like about six feet.

Fuhgeddaboudit.

IO-550-A Looks liquid-cooled. Do you think the radiator is receiving forced air?

And the soles of your shoes.............

Need to see how it handles road construction, traffic bumps, entrance ramps, parking garages, parking lots. Straight smooth roads look good!

Completely impractical.

You are correct. The fact they could run it on the street is amazing.

Looks cool, though.

Extra braking power, no doubt!

Hehe ... take it to Sturgis, I dare you ;-)

[doorgunner69]

Looks like it is meant to go back and forth in straight lines, sort of like HD cruisers and chompers like to do.

Those wheels make for some immense centrifugal force. Anyone that has ridden fast on a windy road or race track knows that makes changing direction hard work.

[Red Badger]

Been there.
Done that.
Lived to tell the story................

[jim_trent]

Looks like it. That shoots down the statement that it was entirely custom made in Brazil. Also, aircraft engines would be the last engine I would use for high speed motorcycle use. They are limited to low RPM (although with high torque at the low RPM).

Where are the lights?

With no fenders or fairing, I bet it's a lot of fun driving on wet pavement.

Is a street sweeper always required to be just ahead of the bike?

[Jmouse007]

Death on wellless.
