Ducati shows Multistrada 1100 and 1100S

The Multistrada 1100 receives a boost in cylinder size thanks to an evolution of the renowned Desmodue air-cooled twin-cylinder engine. For this model the Ducati 1100 Dual Spark now has a displacement of 1078 cc, which offers truly powerful torque and extraordinary reliability.

The new engine benefits from a bore increase of 4 mm to 98 mm, vs. the 1000 Dual Spark’s 94 mm. As a result the cylinder displacement is 1078 cc, a considerable increase on the 992 cc of the previous version.

This new engine now offers a power output of 95 HP at 7750 rpm and 10,5 Kgm of torque at 4750 rpm. These superb values contribute to the bike’s rideability and the powerful mid-range delivery of this modern air-cooled engine highlights the sporting character of the new Multistrada 1100.

The engine has been designed to comply with the Euro 3 norms while, at the same time, boosting performance.

Compact, powerful and acknowledged as the ultimate expression of the Ducati philosophy of air-cooled twin design, the new 1100 Dual Spark Desmo engine that equips the Multistrada family represents the result of decades of experience and a whole series of innovations that extend from the combustion chambers to the crankshaft.

The end result is a powerful engine that is particularly exuberant in the mid-range and generally acknowledged as the most advanced air-cooled L-twin ever designed. In addition to offering the significant advantages of an air-cooled power plant, the 1100 DS also draws inspiration from the advanced Testastretta racing engine, including the special casting techniques used to make the cylinder heads, the use of oil-pressurized plain bearings to support the camshafts, and the angles and configuration of the valves.

All this, plus the exclusive Dual Spark ignition, with its "double flame front", offers more complete combustion, while simultaneously boosting mid-range power and reducing emission levels.

A closer look at the 1100 DS engine reveals a reduced angle between the intake and exhaust valves, one of the basic principles with which the renowned Testastretta engine was designed, which allows for a more compact combustion chamber, reducing the volume and thus obtaining improved combustion. The improved efficiency of the combustion chamber allows the engine to run on a leaner air/fuel mixture without compromising performance at high temperatures and significantly reduces emissions of hydrocarbons (HC).
