Ducati St4s
The Ducati ST4S was introduced in 2001 as the flagship of Ducati's Sport Touring lineup, featuring the more powerful 996cc Superbike-derived engine with Öhlins suspension upgrades over the standard ST4. It was produced through 2005 and is notable for blending genuine superbike performance with long-distance touring capability, making it one of the most capable sport-tourers of its era.

What Buyers Should Know
Desmodue Valve Service
The ST4S requires Ducati's desmodromic valve adjustments every 7,500 miles — a labor-intensive service that can cost $600–$1,200 at a dealer. Always verify service history before buying, as skipped intervals can cause serious engine damage.
Heat & Electrical Gremlins
The ST4S runs notoriously hot at low speeds, and older models are prone to electrical issues including failing rectifier/regulators that can fry the battery. Budget for a regulator upgrade if the bike hasn't already had one.
Stable Resale Value
The ST4S holds its value reasonably well among sport-touring Ducatis due to its rare 996 Superbike-derived engine and limited production numbers. A well-maintained example remains desirable to enthusiasts, making it a smarter long-term buy than most competitors.
