An all-new engine has been created for the ST3, engineered for flexible and smooth delivery of power, low vibration and to maximise fuel mileage. The ST3 focuses on the touring side of sports touring, delivering a high comfort on long journeys while at maximum carrying capacity. Although designed to satisfy those who appreciate the ST3's touring capabilities, flexible power and comfort, it utilizes a frame and chassis that will satisfy the most demanding sports riders.
The ST3 has been carefully designed to provide improved protection from the elements for both rider and passenger. This newest member of the Ducati Sport Touring family is a perfect balance of agility and comfort for a superior experience during long journeys at a spirited pace. The available colours include Ducati red, Ducati Yellow and Ducati metallic grey.
The ST3 utilizes the signature tubular steel trellis frame; renowned for its confident handling characteristics, its lightweight, rigidity and engineering beauty add a sporting feel to the touring experience. Suspension is handled by premium 43mm Showa pre-load adjustable upside down forks and an advanced Sachs rear shock absorber that is adjustable for compression and rebound damping, plus spring preload. The adjustments are simple to use and allow a range of adjustment to satisfy the touring rider without too high a level of complexity
The ST3 introduces the latest engine design from Ducati - the Desmotre engine (Three valve Desmodromic). The Desmotre delivers increased performance over its Desmodue predecessor making 102 Hp at 8,750 revs and 9.5 kgm of torque at 7,250, very close to those of the Desmoquattro Superbike engines. Looking to the future, the advanced Desmotre design will easily allow compliance with the even more stringent anti-pollution limits that will be introduced by the Euro 3 regulations. The new engine has a capacity of 992cc (identical to the 1000 DS) and of course retains the Ducati 90 L-Twin configuration. The liquid-cooled engine uses two intake valves and one exhaust; a practical compromise solution between two already well-tested Ducati valve arrangements. For performance closer to that of the advanced Desmoquattro engine, the two intake valves with large straight intake passages help develop high power and the efficient single exhaust configuration of the 1000 DS engine makes for a powerful yet simple engine.
The engine cases are derived from the 1000 DS Desmodue, with the water pump being integrated into the alternator cover. The Desmotre engine takes advantage of the Dual Spark design as used on the 1000 DS engine introduced last year. The Dual Spark solution helps the ST3 to be environmentally responsible and improves fuel mileage.
The Dual Spark system forms a double flame front in the combustion chamber, lowering emissions and contributing to the smooth torquey power, especially at low rpm.
