In 1987 Exin only marketed one novelty from the STS (Super Track System) series. It was the Pinzgauer support vehicle with reference 2204 and in dark blue, white and yellow colors. Like previous models, it was inspired by the Paris-Dakar Rally and featured four-wheel drive, through an open Mabuchi motor with a double axle fixed diagonally to the chassis, which moved the crown gears of both wheel axles through helical worm pinions. Neither by numbering nor by decoration can we associate Exin's white version to any specific team or edition.
