Air-cooled horsepower. Ducati vs. BMW vs. Guzzi

I do think it would be cool to see a 4V, higher compression, higher hp & torque, 1200cc version of the current engine (perferably with no drawbacks).  It will never happen, but I'd still like to see it. 

Hmm, how hard would it be to put some 4v heads on a 1000ds, double up the oil flow with an extra electric oil pump add another little oil radiator under the seat, and maybe a little muffin fan on the vertical head aka buell?  As long as you watched the temp gauge, you could keep it safe.

As long as the fan isn't as obnoxiously loud as the one on the Buell then that sounds like a good idea to me.

I've seen pics of a prototype 4V air cooled head in a Ducati book, likely one of Faloon's.

4V air-cooled heads are common on the big enduro bikes, but they've got the exhaust side facing forward.

Vertical cylinder on a Duc would be a problem.
Muffin fan may be enough, but I wouldn't bet on it.
Serious oil-cooling, like Porsche, possibly could do it.

All great engines.

A flat twin could be considered a 180 degree V-twin.

A straight twin could be considered a 360 degree V-twin.
