The Ducati ST4s was a sport-touring motorcycle manufactured by Ducati between 2001 and 2005.
The ST4s used the liquid-cooled Desmoquattro (four desmodromic valves) 90° V-twin engine based on the Ducati 996. The Desmoquattro was largely unchanged from the 996 Super-Bike, and retained a valve angle of 40°, but lost 4 mm of diameter on each of the intake throttle bodies (down from 54 mm on the 996). Chassis clearances also required the use of the more compact cylinder head design that was shared with the 748 Super-Bike and Monster S4. In spite of the smaller intakes, the ST4s actually made slightly more power and torque than the 996 Super-Bike due to the mostly straight-through design of the ST's exhaust, compared to the under-seat exhaust of the Super-Bike.
The chassis design was based on the ST4 but with the larger engine, and improved suspension. Otherwise it was a competent trellis framed sports tourer with a protective fairing, and standard colour matched luggage (luggage was optional on other ST series models). The ST came equipped with a center-stand, an accessory power outlet, and both the ST4s and ST3s could also be equipped with ABS from 2003.
In 2004, an upgrade to the ST line brought a slightly redesigned nose fairing and dashboard, adjustable ergonomics, a trip computer, four-way (hazard) flashers, digital speedometer, a dashboard-controlled adjustable headlight, a new seat design, Euro-2 catalytic exhaust (except USA - Euro-3 was achieved in the 2006 ST3), and a simplified CAN-bus wiring setup. The refinements reduced weight by 11 kg (24 lb) due to the lighter wiring harness and simpler support structure for the nose of the bike.
