I thought (wrongly I guess) that the dealer would have by default, done an oil change before delivery to customer on a used bike.
That's never been my experience. As @GreyGhost mentioned, that would significantly bite into margins.
The oil wasn't bad by any means (see photos above) aside from what I'm thinking (but could be entirely wrong) was moisture, but like I said, I always like to start with a baseline on fluid changes so I know what's in there and when it was done. Previous owner might have used the cheapest or incorrect oil for the engine, for example, so it's always best to start clean and fresh. Or it could have been Motul 1, fed to Swiss cats, refined by their digestive system and is collected after they poop it out, and I just wasted $200 in oil by changing it 30,000km before it really needed it, but it is what it is.
