The 1975 860GT was the last year of Ducati's original Giugiaro-styled big twin tourer, using the 864 cc bevel-drive V-twin with a single 280 mm front disc and a rear drum. Sales of the square styling were poor, which led to the restyled GTS the following year. A US version had its gearshift moved to the left side.
