Overview

Introducing the 1967 Ducati 250 Diana, a quintessential piece of Italian engineering that encapsulates the spirit of the 1960s motorcycling scene. Positioned firmly in the sport category, the 250 Diana is a motorcycle that blends performance with lightweight agility, making it a favorite among enthusiasts and casual riders alike. With its sleek lines and distinctive Ducati styling, this bike is not just a mode of transport; it's an icon of its era, celebrated for its spirited performance on both city streets and winding country roads. At the heart of the 1967 Ducati 250 Diana lies a robust single-cylinder, four-stroke engine, boasting a displacement of 249 cc. This powerplant delivers 19 horsepower at 7,750 RPM, allowing the bike to achieve a top speed of 150 km/h (93.2 mph). The engine's 8.0:1 compression ratio and finely-tuned Dell'Orto 29mm carburettors ensure that the bike provides a thrilling yet manageable ride. Its lightweight chassis, tipping the scales at just 135 kg (297.6 pounds), yields an impressive power-to-weight ratio of 0.1407 HP/kg. This makes the 250 Diana incredibly responsive, allowing riders to enjoy a nimble and exhilarating experience, whether navigating tight corners or cruising along open highways. The 1967 250 Diana is equipped with features that enhance both performance and comfort. Its hydraulic telescopic front forks and dual shocks at the rear provide a smooth and stable ride, while the expanding drum brakes—180 mm in diameter at the front and 160 mm at the rear—offer reliable stopping power. The bike's classic design is complemented by a simple yet effective air cooling system, ensuring that the engine remains at optimal temperatures during spirited rides. Every aspect of the Ducati 250 Diana reflects a meticulous approach to engineering, making it a timeless classic that resonates with motorcycle aficionados. **
