The Ducati Mark 3 was a standard motorcycle produced by Ducati between 1968 and 1974. It was a replacement model for the Ducati Sebring and powered by a 340cc single-cylinder bevel drive SOHC engine.
In addition to the base model, the maker produced a higher specification model available wearing the Mark 3D designation. It packed a different head derived from the 350SCD model, using desmodromic valves.
In 1971, the Italian motorcycle manufacturer released the Ducati Mark 3D, which packed the same engine as the base model but with desmodromic valves and shared its cycle parts. It was also available with optional features, such as a race kit, a fairing, and a megaphone silencer.
In the visual department, the bike packed features such as a round headlight up front with analog instruments mounted on top, a one-piece dual seat with a passenger strap belt, dual, side-mounted rear shocks, a single exhaust system mounted on the right side, and lightweight wire-spoke wheels.
As for the power figures, the 1971 Ducati Mark 3D had installed a 340cc four-stroke single-cylinder air-cooled engine at its core managed by a Dell'Orto carburetor, delivering 34 hp with maximum strength at 8,500 rpm.
The bike was set in motion by sending the power to the rear wheel via a five-speed transmission and a final chain drive, pushing it to 170 kph (106 mph).
