When talking about Ducati bikes with some serious racing pedigree in the 60’s, the Ducati 250 Diana has to be mentioned because it was the very first sporting 250 model that every young man had his eyes set on.
Aesthetically, the racing heritage was pretty evident, specifically the addition of racy clip-on handlebars, handsome new styling, and crackling exhaust note. It also weighed just 265 pounds, making its 249 cc SHC single engine more than capable of being a barn burner.
The horsepower output from the 250 Diana reaches 24 ponies and was capable of blasting off at a top speed of 85 mph. Eventually, the 250 Diana’s success spawned itself into a new model - the Mark 3 Super Sport - one that was more than adept at producing a stout 30 horsepower and mated to a five-speed transmission.
Any corrections or more information on these motorcycles will be kindly appreciated. |
