Paramedic version of the V-strom in Serbia
(not my pic- stolen from Wikipedia)
Have seen a GTR1400 (black) used as an one-marked bike by South Wales Fuzz, along with an older CBR600 (white)
There have been some 650GS's used in large urban police forces to combat kids on nicked bikes in local parks and waste ground.
Think the local environmental enforcement lot use some various small offroad bikes to inspect areas used by trail riders, but they won't have blue lights
