The Ducati ST4S – a motorcycle that defies categorization with its bold blend of high-performance components. Its four-stroke, 90-degree twin-cylinder engine, lifted directly from the 996, delivers a unique soundtrack and impressive torque delivery.
As we discovered during our extensive test period, the ST4S is more than just a collection of parts; it’s a harmonious union of engineering expertise and Italian flair, resulting in a truly exhilarating riding experience. The chassis, drawn from Ducati’s sportbike stablemates, provides exceptional handling, while the USD Showa front end and Ohlins rear suspension work in perfect harmony to soak up the road imperfections.
But it’s not just about numbers and specifications; the ST4S is a motorcycle that rewards its rider with an unparalleled level of engagement and connection. Its engine character, with its smooth power delivery and characteristic “dual-cylinder” thrum, makes it a joy to ride in any situation, from spirited blasts through twisties to relaxing cruises on the open road.
