I looked into this a while ago.
there are no engines available as spares so the only way of obtaining
one is to buy a bike and throw away the frame.
the bikes cost $33,000 australian dollars
a jabiru engine is less than half that and it was designed as an
aircraft engine.
does that make any sense to you?

German ebay lists quite a few for reasonable price:http://cgi.ebay.de/Motor-BMW-R-1100-...ne-TOP_W0QQite...

If I'm not mistaken, those are all BMW "OilHeads" as opposed to the
older "AirHeads". One nice thing about either is that parts are still
available. The Airhead engines are a LOT simpler (aircooled 2 valve
pushrod), but make less horsepower. They may well be lighter too. I
weighed one of my R100 engines many years ago, I think it came in
right around 100 pounds without the exhaust system. I don't know what
they 'claim' for HP, but it isn't much.
