That’s a Continental IO-550-A. Horizontally opposed 6 cylinder. Made in Alabama.
It’s got to be hot sitting right behind that air cooled engine.
Looks like a flat 6 rather than the V6 mentioned in the story. Is it flat, or a really, really shallow V?
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?
IO-550-A Looks liquid-cooled. Do you think the radiator is receiving forced air?
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).
Those look more like Tiara cylinders - 550A induction is on the bottom..so it could be a 540cu in motor (stock bores), or over-bored slightly. Those motors are obsolete as far as I know.
I think the Rolls Royce claim is just marketing...
