The popular Enduro BMW R 80 GS and the R 100 GS underwent a comprehensive model update for the model year 1991. Customers mainly perceived this update through the new visual appearance, which was partly based on the "Paris-Dakar". It included half fairing bolted to the frame with external tubular brackets, a rectangular headlamp unit and a modified instrument panel. The technical innovations featured an enlarged oil sump, a new Marzocchi spring strut, a semi-floating brake disc on the front wheel, new handlebar fittings and a safety tank lid.
