The DUCATI ST4 (1998-03) ST4 is an Italian sport-touring motorcycle, not a car. It pairs sporting performance with a fairing and riding position suited to longer road journeys. In the UK used market, it is an enthusiast-focused alternative to everyday commuter bikes, with distinctive Ducati styling. mycarcheck.com has recorded 40 look-ups covering 25 different VINs, so this is useful market context but a modest sample, not a complete picture. Those checks show an average private-sale valuation of £1,300 and average recorded mileage of 27,000 miles. Average annual use is just 1,000 miles, while bikes had nearly five previous keepers on average. That low annual mileage may suit weekend riders and touring fans seeking a characterful used Ducati, though condition and service history deserve careful attention. Compared with more practical, less distinctive rivals, the ST4 is best for riders who value engaging road manners and Italian character over low-cost, all-purpose transport.
