Ducati 350 Mark 3 D (1969 - 70)

The Ducati 350 Mark 3 D is a true icon of Italian motorcycling heritage. With its SOHC, bevel gear driven single cylinder engine producing 38 horsepower at 7,800 rpm, this motorcycle embodies the essence of raw power and agility.

The bike’s all-alloy construction, featuring polished cases and massive finning on the barrel, exudes a sense of craftsmanship and attention to detail. The 5-speed unit construction gearbox with heel/toe shifter allows for seamless gear transitions, further enhancing the riding experience.

But it’s not just about speed; the Ducati 350 Mark 3 D is also designed with rider ergonomics in mind. With its narrow cases and frame, tank, and footpegs, this motorcycle provides a level of adjustability that’s unmatched by many of its contemporaries.
