BMW boxers

[LongRanger_imp]

I've had three boxers and am now on my fourth. I've never had an issue with the opposed cylinder heads, but I've never dropped any of these bikes, either. The valve covers are inexpensive (<$100) if you do have a mishap, but you're not going to break the cylinders off the engine block if that's what you're worried about. But as I wrote elsewhere, ride one before you fall in love with it. You may not care for the engine and gearbox.
