Aero engined bikes

Well we all know that the boxer began life powering aeroplanes. These guys have taken another aero engine and built a bike round it. Never seen the like of this before.

I don't know if these apply to a radial engine, but try to imagine adjusting the valves, balancing, or just changing the spark plugs for that matter. javascript:emoticon(':shock:')

Other than the novelty of bolting a radial engine in a motorcycle frame, I don't see the benefit. Too much complexity.

Must be one heck of a riding experience though, at least initially.

Would you want to clean it...?

If it were a 'rotary' engine, now that[/u] would be even whackier!!

Rog,
Suzuki tried that way back in the 70's, it was an ok bike, they offered it for a couple years,
before realizing that no one was going to buy it. So it died quietly. I found this link about the RE5. You might find it interesting.

I think Rog is referring to the aircraft rotary engine, which anchors the crankshaft to the airframe and spins the whole engine -- which has the propeller attached. This enhanced cooling, at the expense of a fierce gyroscopic effect. Some WWI aircraft used these engines.

I thought about that too, scary. "Man eaten by own bike" headline...

Oh yeah, the spinning rotory engines.....might as well make that the next step.

If the engine "spun" the right direction it would be a wheelie MONSTER.

Imagine dumping the clutch when the "flywheel" effect of that huge hunkamotor was spun up!

And think of the envy from those guys that shelled out the big bucks to have spinning hubcaps......
