150 5V Arcore

The 125 and 150 versions of the 5V Arcore, presented at the Milan Fair in 1971, replaced the previous single-cylinder, four-stroke, five-speed gearbox versions with the same displacement that had been a point of strength of production in the late 60's. It was not, however, a mere facelift but a true revamping: the engines were highly "undersquare", the fins had a square shape and the crankcase had a new design. The general approach was the classic Gilera style, including the last use of a gearbox with foot pedal to the right of the crankcase and overhead valves with double parallel cylindrical springs. The lower continuous double cradle frame, with reinforcement triangles in the most stressed points, had been considerably modernised.
