had similar issues with the brakes on my bike (not a 650GT), nothing out of place but it makes that exact same sound. turns out there is a number of pebbles/stones stuck between the pads and disc, which makes that sound at low speed. After a very thorough blow of compressed air it thankfully went away... might be the same case with yours.
Haha you blur out your speedo but we can see your speed in the reflection off your wind visor...

Yup most likely it is.
