The 1967 Ducati 250 Diana
The 1967 Ducati 250 Diana represented the final year of production for this sportier single-cylinder offering in Ducati's smaller displacement lineup. Built around a 249cc single that punched out 19 horsepower at a relatively high 7,750 rpm, the Diana was engineered for riders who wanted genuine sport bike character without the complexity or cost of larger twins. The high-revving nature of the engine rewarded an aggressive riding style, and the 93 mph top speed was respectable for a quarter-liter machine of the era. This was a bike that taught proper throttle control and cornering technique while still being approachable enough for intermediate riders stepping up from smaller machines.
The 1967 model carried over without significant mechanical changes from the prior year — buyers comparing it to a 1966 example should focus on mileage, service history, and condition rather than spec differences. Today's 250 Diana appeals to collectors who appreciate the purity of single-cylinder sport bikes and riders seeking an authentic vintage Ducati experience without the premium pricing of the larger displacement models. The moderate collector interest means examples still trade at reasonable prices, making them accessible entry points into classic Ducati ownership.
