It certainly appears to be the transmission output seal. So Brian, you're thinking this will be a spendy fix, right?
It's a BMW, its going to be expensive. Just sign the title over to me, I'll remove the offending bike (leak and all) free of charge. Then you'll have room for a new *something*.
(yea - I have no idea how much it will cost or how hard it will be to fix).
