Your friend will be able to "see" the fuel quality on the R1200GS / LC, just by looking at the fuel range number on the dash after refuelling . No need even for the engine to run.
No idea how the thing works but it does... Incredibly high number like 500 to 570km range = low octane.
Normal range (380 to 420km) = normal fuel.
If anyone knows how this works, I'd love to know.
