The Ducati 860 GT was a Ducati motorcycle made in 1974 and 1975, replaced by the restyled 860 GTS for 1976–1979. In 1974–1975 the electric-start version was called the 860 GTE, while all models had electric start after 1975, and for the final two years, 1978–1979, the name was changed to 900 GTS. A USA market variant was made in all model years, in which the gearshift was "crudely moved" from the left to the right side of the engine by means an external rod.

The 860 series used the engine and stressed member frame of Fabio Taglioni's original 750 GT L twin, with bevel cam drive and with the enlarged capacity achieved by using two of the Ducati 450 single-cylinder engine’s sleeves and pistons. The controversial angular design of the cosmetic elements was by noted car stylist Giorgio Giugiaro. Giugiaro dispensed with both the sinuous tank shape and engine covers, and added large steel side covers to create an overall integrated effect. The upright seating position was intended for urban riding rather than the sporting leaning over position of the earlier 750.

The 860 GT was renamed the 860GTS in 1976 and featured a less angular fuel tank than the GT; a seat without the duck-tail; lower, narrower handlebars and a decreased final drive ratio. By 1977 further cosmetic and electrical enhancements were introduced in the again renamed 900 GTS. Production ceased in 1979, with these later bikes having engines mechanically similar to the Darmah SS and SD bikes that replaced them.

The GTS version of the 860 ducati was a much nicer looking bike than the previous GT bike. The GTS version is also somewhat rare as there just were not many sold and few have survived. The gas tank had a much nicer shape as did the seat . Gauges were more in the style of the early 750 Sport.

Any corrections or more information on these motorcycles will be kindly appreciated.
