Built in 1953 to join the ranks of the Ducati 98 N and the Ducati 98 T OHV, the 98 Sport became an immediate success in the market, despite its modest performance capabilities. At the heart of the Ducati 98 Sport is a 98 cc OHV single cylinder engine that’s been mated to a four-speed transmission. The powertrain was capable of producing 6.8 horsepower with a top speed of 56 mph. Those numbers may not mean much compared to the bikes Ducati has in its line-up today, but back then, that was enough to make the 98 Sport one of the most popular bikes the company’s range.
