1964 Ducati Diana Mark 3

The Ducati Diana Mark 3 1964 represented Ducati's refined approach to lightweight sporting motorcycles, sitting as the evolved flagship of their quarter-liter Diana series. This single-cylinder machine delivered genuine sporting performance in a package that rewarded smooth, committed riding rather than ham-fisted throttle work.

Built around a sophisticated single making 24 horsepower at a relatively high 7,500 rpm, the Diana Mark 3 was engineered for riders who understood that small-displacement performance meant keeping the engine singing in its sweet spot. The bike responded well to regular maintenance and deliberate riding techniques, offering a direct connection between rider input and machine response that larger, more forgiving motorcycles often mask. Its quarter-liter displacement placed it squarely in the sporting lightweight category that European manufacturers dominated during this era.

The 1964 model carried over without significant mechanical changes from the prior year — buyers comparing it to a 1963 example should focus on mileage, service history, and condition rather than spec differences.

Today's Diana Mark 3 buyers typically fall into two camps: serious Ducati collectors building comprehensive early collections, and experienced riders seeking an authentic 1960s sporting experience. The moderate collector interest means prices remain accessible compared to later desmodromic models, though clean examples command respect.
