The Ducati 350 Mark 3 was a standard motorcycle powered by a single-cylinder bevel drive SOHC engine. The bike was manufactured from 1968 to 1974 and was one of Ducati's first wide-case single-cylinder motorcycles.
In addition, a higher-performance version of the Mark 3 was produced under the Mark 3D designation, which used desmodromic valves. The maker manufactured 2,300 Mark 3 models and 1,350 Mark 3D versions.
In 1968, the Italian motorcycle manufacturer launched the Ducati 350 Mark 3, a standard motorcycle with the same bore and stroke as the Sebring model but with a higher compression ratio, hotter cam, and a bigger carburetor.
In the visual department, the 1968 motorcycle packed features, such as a round headlight up front, a one-piece dual seat with a passenger holding strap, side-mounted rear shocks, a single exhaust system with a silencer on the right side, and lightweight wire-spoke wheels.
The bike was built around a steel frame with a hydraulic telescopic fork on the front and dual side-mounted shock absorbers on the rear, acting as suspension. The braking performance was achieved by a single 180 mm drum unit on the front wheel and a single 160 mm drum unit on the rear wheel.
As for the power figures, the 1968 Ducati 350 Mark 3 had installed a 340cc four-stroke single-cylinder air-cooled engine underneath its fuel tank, delivering 34 hp with maximum strength at 8,500 rpm.
