1971 Ducati 450 TS Technical Analysis & Specification Breakdown

Positioned in Ducati's naked motorcycle lineup, the 1971 Ducati 450 TS pairs a 435 cc (26.5 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 20 HP (14.6 kW) at 5,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 46 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.

On the scales, the 450 TS measures 155 kg (342 lbs) wet (curb), translating to a power-to-weight ratio of 0.13 HP/kg (7.75 kg per horsepower). The 15-liter (4 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 125 km/h (78 mph).
