The 1965 Ducati 250 Diana

The 1965 Ducati 250 Diana represents Ducati's entry-level sport offering from the mid-1960s, positioned as an accessible gateway into the Italian brand's performance-oriented lineup. This quarter-liter single delivers genuine sporting character with its 19 horsepower at 7,750 RPM, rewarding riders who enjoy wringing out a smaller engine rather than relying on brute force. The Diana feels nimble and eager, particularly suited to twisty back roads where its lightweight nature and chain final drive let you carry momentum through corners. It's the kind of bike that teaches proper riding technique while still providing enough punch to be genuinely entertaining.

The 1965 model carried over without significant mechanical changes from the prior year — buyers comparing it to a 1964 example should focus on mileage, service history, and condition rather than spec differences. Today's 250 Diana attracts two distinct groups: vintage Ducati collectors who appreciate its role in the company's sporting heritage, and experienced riders seeking an authentic 1960s Italian lightweight. With moderate collector interest continuing to build, well-maintained examples appeal to enthusiasts who want classic Ducati DNA without the complexity or cost of larger displacement models.
