This is an air/oil cooled engine: essentially it's aircooled, but BMW run
oil galleries past the exhaust valve seats (claim: lowers temps there by 70
C.) before passing it through an oil cooler and back to the sump.
Apart from an old version of the motronic engine management system (2.2 vs
around 6.0 for the cars) it's a fairly up to the minute engine and certainly
on the shortlist -especially as spares distribution is likely to be even
more widespread than Rotax... if you need them. (Rather cheaper too, I'll bet)
