Ducati 350 F3

In 1985 the Ducati F1 750 was released, based on the TT1 and TT2 racers, with full flow oil cooling rather than cylinder head bypass cooling, and cantilever rear suspension. The first production bikes used the same size valves as the 500 had, restricting performance.
With its 1400 mm wheelbase, it was a smaller 750 than the world was used to, and ancillary parts were of mixed quality.
Larger riders found it small, and the 16-inch (410 mm) front wheel restricted tyre choice. Distinctive features included 38 mm Marzocchi front forks, fully floating rear disc brake, Nippon Denso instruments, and an aluminium petrol tank.
This was the same year the liquid-cooled Desmoquattro models appeared. While air-cooled models are still produced, development since has focussed more on the liquid-cooled models.
In 1986 the 750 F1 crankcases were strengthened, and now used straight cut primary gears driving a hydraulically activated dry clutch, and stronger gearbox.



The valve sizes were increased to 41 mm and 35 mm, as used on the TT2, and this meant smaller 12 mm sparkplugs were fitted.
Other features were 40 mm Forcella front forks, Veglia instruments, and a steel petrol tank. The 750 F1 continued to be produced in 1987 and 1988.

There were three limited edition models; the Montjuich, the Laguna Seca, and the Santa Monica. These used 40 mm Dell'Orto carburettors, hotter camshafts, a two into one Verlicchi exhaust, 4 piston Brembo calipers with fully floating discs all round, and an aluminium swingarm. These are considered the best of the 750 F1 models.


From 1986 to 1989 the factory made 2 sister bikes manly for Italian tax reasons, the F3 350 en the 400 F3
This one got a 550 cc Kit installed.
