Key specifications
Overview
Introducing the 1963 Ducati 250 Diana, a true gem in the realm of classic motorcycles that perfectly embodies the spirit of Italian craftsmanship. Designed for the sport category, this lightweight and agile machine was built to cater to the demands of both spirited riders and enthusiasts yearning for a slice of motorcycle history. Positioned as a bridge between everyday commuting and exhilarating weekend rides, the Ducati 250 Diana was a game-changer in the early '60s, appealing to riders looking for both performance and style. At the heart of the 250 Diana lies a robust single-cylinder, four-stroke engine with a displacement of 249 cc. Producing a spirited 19 horsepower at 7,750 RPM, this engine is a marvel of mechanical design, delivering a top speed of 150 km/h (93.2 mph). The bike’s air-cooled configuration, combined with a compression ratio of 8.0:1 and Dell'Orto 29mm carburettors, ensures a smooth and responsive ride that is both engaging and accessible. Riders can expect nimble handling, thanks to its lightweight frame, which weighs in at just 135 kg (297.6 lbs). The power-to-weight ratio of 0.1407 HP/kg translates to an exhilarating experience, making each twist of the throttle a thrill. The Ducati 250 Diana is not just about raw power; it also boasts an array of features that enhance the riding experience. The bike is equipped with hydraulic telescopic forks at the front and dual shocks at the rear, providing a balanced and comfortable ride over varied terrains. For stopping power, it employs expanding drum brakes both front and rear, with a 180 mm diameter in front and a 160 mm diameter in the rear, ensuring adequate control during spirited rides. With a fuel capacity of 13 liters (3.43 gallons), the Diana offers ample range for weekend jaunts. Coupled with its classic kick starter, the 250 Diana stands as a testament to the simple yet effective engineering of its time. **
