Sorry. Not trying to cause a panic, just sharing the little bit I know. I'll shut up now. I lost coolant from the radiator also when the seal was bad so that won't be what is troubling you.

Mine does that every once in a while when I'm really hammering it over a number of days. The radiator will be full and the overflow bottle will be empty or really low after a ride. No idea where it goes but the bike seems fine.
