The Ducati 250 Diana is an iconic symbol of the Italian motorcycle manufacturer’s foray into high-performance sports bikes in the early 1960s. Its sleek, racing-inspired design – complete with clip-on handlebars and a distinctive exhaust note – was the epitome of style and substance. With its lightweight frame tipping the scales at just 265 pounds, the 249cc SHC single engine proved to be a potent combination, delivering a punchy 24 horsepower and a top speed of 85mph.
Riding a 250 Diana is an experience like no other – the bike’s responsive handling and agile demeanor make it a joy to navigate twisty roads and corners. And yet, despite its relatively modest power output, the Diana has a raw, unbridled energy that’s impossible to ignore.
Built on the success of this model, the Mark 3 Super Sport was eventually born, boasting an impressive 30 horsepower and five-speed transmission – but it’s the original 250 Diana that remains the true gem of Ducati’s early racing pedigree.
