R1100R - Is this a battery vent hose?

I just picked up a '00 R1100R. Overall it's in excellent shape, 20K miles and well maintained. It had this hose dangling from the RH side. I assume this is just an old battery vent hose from an original battery that has since been replaced by a sealed Yuasa.

Is that correct or should I go hunt around for some unconnected vent port?
