Overview

Introducing the 1968 Ducati 250 Mark 3D: A Slice of Italian Sport Heritage The 1968 Ducati 250 Mark 3D stands as a testament to Ducati's commitment to crafting agile and spirited motorcycles during the golden age of motorcycling. Positioned within the sport category, this model was aimed at riders who craved a nimble bike that could tackle both city streets and winding country roads with equal flair. With its classic Italian styling, the Mark 3D captures the essence of the late '60s, merging aesthetics with performance. Its relatively lightweight frame and compact dimensions make it an ideal choice for both novice riders and experienced enthusiasts alike, offering an engaging ride that reflects the spirit of the era. At the heart of the Ducati 250 Mark 3D lies a single-cylinder, four-stroke engine with a displacement of 249cc, delivering a spirited 20 horsepower at a thrilling 8,000 RPM. This lively powertrain allows the bike to reach a top speed of 160 km/h (99.4 mph), making it more than capable of keeping up with the demands of spirited riding. The 9.7:1 compression ratio and two-valve configuration contribute to its efficient and responsive power delivery. Riders can expect a smooth experience thanks to the 5-speed gearbox, which encourages quick shifts and allows for optimal performance on varied terrains. The combination of air cooling and a carburettor fuel system ensures reliability while keeping the weight low, making the Mark 3D a joy to handle. The engineering ingenuity of the 250 Mark 3D is evident in its chassis and suspension design. Built on a simplex open cradle tubular steel frame, the bike is both sturdy and lightweight, enhancing its agility. The hydraulic telescopic front forks provide 120 mm of travel, effectively absorbing the bumps in the road, while the swinging arm rear suspension, equipped with adjustable hydraulic shocks and offering 70 mm of travel, ensures a comfortable ride. The dual drum brakes—both front and rear—offer dependable stopping power, a hallmark of Ducati's dedication to safety and performance. Additionally, with a seat height of 735 mm, riders will appreciate the accessible riding position, which adds to the overall user-friendly experience. **

    • Engaging Performance: The spirited engine and responsive gearbox provide an exhilarating ride, especially on twisty roads.
