just read about the new BMW S 1000 RR bike. The complete engine assembly
is less than 60 KG. Engine puts out 193HP (112 Nm, 12,000rpm). Wouldn't
that one (slightly detuned) make a nice SLA powerplant ;-))

Possibly, but what horsepower can it produce at 3000 RPM? And if that
is not enough, what reduction gear assembly do you want to use?

And yes, BWM horizontal twins HAVE been used on light aircraft, along
with Citreon twins.
