Ducati 400F3 (1986)

Ducati 400F3 (1986)

The Ducati 400F3 – a diminutive dynamo that packed a punch in the limited sport bike market of the 1980s.

Japanese enthusiasts knew it as the 400-cc F3, generating 47 horsepower and boasting a respectable top speed of 110.8 mph. Its Italian counterpart, the 350cc F3, produced 42.5 horsepower.

Underpinned by the same trellis frame that would become the backbone of every road-going Ducati since, the F3 was a stripped-back version of its bigger brother, the F1. Suspension and brakes may have been lower-spec, but this only added to the bike’s raw, race-bred appeal.

Ride the 400F3 and you’ll experience the essence of Ducati’s ‘real’ era – uncompromising, unapologetic, and utterly thrilling.
