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 ;-))

193 HP ??? Are you positive about that number? I would like to see where
that number came from, if it is available on the net, if you wouldn't mind.

If it is correct, that should do rather nicely. People have flown BMW bike
engines in the past. I believe that most of the successful ones have used a
different gearbox to reduce the prop RPM. Seems to me that I remember that
they adapted a Rotax gearbox to the job, but I doubt that there are any
Rotax gearboxed that could handle 193 HP.
