Hi all - I’m a new Street Twin owner and really appreciate the help I have already received on the forum. As I’m learning the ins and outs of this bike, can you take a look at these photos and let me know if you see anything concerning?

I noticed some white dried marks on the lower left casing today and it looks like something dripped down onto the casing from above. Here are a few photos.

Is this built up condensation from the outside? Or does it look like something leaking from the inside?

Thanks all!

How new/old is the bike? In the fourth photo, the markings on that one part indicate, to me, that is not original. In the first photo, I see two spots that bear further inspection. Follow the left vertical "post" up the cooling fins to just below the top of that section; there seems to be residue there. Straight up from the "Bonneville 900" tag on the top of the second set of cooling fins, there seems to be more residue.

It does look like something has dripped from the top as Geyfell pointed out. You did not have any spillage when you last put gas in the tank did you. This does not seem like a constant drip but more like a one time thing.

In the last picture it looks like a coolant leak under what appears to be the thermostat housing. Could have leaked and migrated across to the other side when bike was on it's sidestand. Was this noticed after a washing/rinse? Is the coolant level good?

I would clean it up and see if the stains reappear. Sometimes the easiest fix is the correct one. Good luck.
