The Benelli 124 was unveiled and put into production in 1982. It featured modern lines which followed the aesthetic tendencies of the late 1970s and early 80s. The carburettor was square and incorporated within the fairing, while the saddle was long and wide. The 124 was available with two paint-jobs: white with blue detailing and red with yellow details. On the technical side, it boasted a 123 cc four-stroke parallel straight twin engine with vertical cylinders. As regards the structure, it was composed of a closed duplex cradle made from steel tubing, Marzocchi front fork and rear swingarm with adjustable Sebac shocks.
