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. The 98 Sport sold in London in 1956 for ₤178 10s, which would be ₤3,979 as of 2016, after inflation.[2]

Ducati was one of several Italian companies that did well in the 1950s with lightweight sporting motorcycles like the 98, especially the 98 Sport, 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."[8]

Development

The series was envisioned as a "bare-bones low performance model,"[9] but the 98 Sport of 1953 became Ducati's "first true sporting model."[10] The new design by Ducati's chief engineer, Giovanni Fiorio, made its debut at the 1952 Milan Show with the showing of the 98N and 98T (with twin seat).[11] The following year, the 98 Sport was presented at the same show, a lighter bike with alloy instead of chrome steel rims,[5] and a higher state of tune, and the addition of a finned oil cooler at the front of the engine.[12][13]

Although the 98 had some success in competition,[7][9] its limitations made Ducati Director Giuseppe Montano decide to begin a racing program led by a new engineer, Fabio Taglioni.[12] Though Taglioni mainly worked on the new OHC bikes, he might have influenced the 98S of 1954.[14]

Popularity

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.[2][7] The series would prove to be one of Ducati's most successful early efforts.[14] 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.[5][15]

Today the 98 Sport is the model of this series most sought after by collectors and restorers. The other versions, while originally more numerous, today suffer from a scarcity of parts and relatively low resale value.[16]

Though similar in name, the Ducati 98 TS (aka 98 Bronco) was different than the earlier 98 range, having a milder-tuned engine (7:1 compression) and a new duplex full-cradle tubular steel frame.[17]

98 Super Sport mystery

There are questions as to the existence of the 98 Super Sport, as a distinct model from the 98 Sport. While authors Ian Falloon and Mick Walker describe such a version,[3][10] saying it was faster and lighter than the 98 Sport, with Walker adding that the 98 SS is very rare and sought after by collectors,[16] other evidence, such as photographs of the elusive 98 SS, is lacking. One explanation is that the name "Super Sport" was used instead of "Sport" after 1955 as a marketing label, rather than a technical distinction, to describe the last, and best performing, of the 98 Sport models.[18]

"Communque, la denominazione 98 SS viene ignorata sui documenti della Casa; serviva forse per definare in termini pratici e commerciali, anziché tecnici, l'ultima e piú brillante linea della 98 S." Translation: "...the SS name is ignored in the Ducati official documents: it was probably meant to indicate in practical and commercial terms, rather than technical terms, the last and more performing line of 98 S models."
