The Ducati 125 Cadet/4 was one of the last Ducati bikes to carry the pushrod overhead-valve single cylinder engine. Making it even more attractive as a collector’s piece is that the bike only lasted two years because Berliner, the U.S. distributor of Ducati, decided they were not suitable for the American market.

The 125 Cadet/4 also shared many cycle parts with the two-stroke engine, although the engine was still based on the aforementioned overhead-valve unit. Nonetheless, a number of items on the list were changed, particularly the bore and stroke and the cylinder head design. Likewise, the spark plug was moved to the right, and the two overhead valves were set parallel.

The double cradle tubular steel frame was also similar to another Ducati bike, the 125 Bronco. Finally, the 125 Cadet/4’s 121 cc single-cylinder OHV four-stroke engine was mated to a four-speed transmission. It didn’t have the kind of power that would win races, but it sure did carry enough for a bike made by Ducati.
