What part of the motorcycle is this please?

Hi folks. Can't upload video so link to my Google drive. Can someone tell me what this is for? It's holding some kind of liquid that says low....my fuel tank is full, so is engine coolant and oil so what is it? Thank you https://drive.google.com/file/d/1rmUDmbq_ENXxBCpgdzzFd9mvHiQyRHBf/view?usp=drivesdk

that's the coolant expansion tank iirc? Your radiator maybe full, but this also needs coolant in it as it ebbs and flows with the heat.

Thanks for the reply mate. How do I fill this up seperate to the main engine coolant storage?

There's usually a black top hose near the side of the airbox.

Should be able to find it on Google/Youtube. Get yourself a Haynes manual too if you're not too familiar with the bike.

The filler is under the tank, here's the page from the owner's manual
