Before the Ducati 175 broke into the scene, the Ducati 125 Sport was the quintessential early Ducati single. the Ducati 125 Sport was in a league of its own, weighing only 221 pounds and featuring a 124 cc SOHC single engine that produces 10 horsepower and mated to a four-speed transmission.

The 125 Sport was capable of hitting a top speed in excess of 70 mph, and when combined with a design that’s as streamlined as any Ducati bike ever built, it was the perfect on-the-road companion for all those merry joy rides.
