The Ducati 98, 98N, 98T, 98TL, 98 Sport (98S) and 98 Super Sport (98SS) were a series of single-cylinder OHV, open-cradle pressed-steel frame motorcycles made by Ducati Meccanica from 1952 to 1958.
Ducati was one of several Italian companies that did well in the 1950s with lightweight sporting motorcycles like the 98 because production recovered relatively quickly after WWII, and because the designers understood that "a model with a racing pedigree, stylish looks, and a bit of excitement was, in the Italian designer's mind, likely to sell in larger numbers than a dull looker, no matter how well engineered, comfortable, and practical."
Reviewers at the time found the bike expensive, but were generally positive, liking the sporting feel of the suspension, gearing and brakes, as well praising the fuel economy and the Italian styling. The series would prove to be one of Ducati's most successful early efforts. The price, performance, and stylish looks of the 98S became popular in the Italian la passeggiata (street cruising scene) of the era and sold well in the home market.
