History
The 98 was designed by chief engineer Giovanni Fiorio and was shown at the Milan motorcycle show in 1952, as the 98N and 98T. It was a single-cylinder pushrod overhead-valve engine with a telescopic fork and a swingarm with hydraulically damped rear springs. Later came the four-speed 98TL and various sports versions.
The 1953 98 Sport was Ducati’s first real sports model, with aluminium rims, higher compression and an oil cooler at the front of the engine. It sold well in Italy. The 98SS may only have existed as a sales name for the last, most powerful Sports. The 98 TS ‘Bronco’ carries the same name, but is a different design.

What to check when buying
- The 98 Sport is the most sought after. Check that a ‘Sport’ really is a Sport: aluminium rims, front oil cooler and four gears.
- For the other versions parts are harder to find and the value is lower. Allow for that if something is missing.
- Do not confuse the 98 with the 98 TS Bronco, which has a different frame and engine.
- Compare the frame and engine numbers with the papers.
- Test the drum brakes and check that the fork does not leak and is not bent.
