At the heart of the 1975 Ducati 125 Regolarita allround motorcycle, Ducati relies on a 123.7 cc (7.6 cu in) air-cooled single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 29.2 HP (21.3 kW), transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 236.1 HP per liter, the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the 125 Regolarita measures 114 kg (251 lbs) dry, translating to a power-to-weight ratio of 0.26 HP/kg (3.9 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,420 mm (55.9 in) wheelbase engineered for balanced agility and highway composure. The 7.2-liter (1.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
