Chassis

The renowned Multistrada chassis remains unchanged, guaranteeing exceptional stability at speed, as well as fantastic agility through fast bends, thus allowing expert riders to find it easy to achieve blistering performance with the 1100.

The round tube Trellis frame is made from high quality steel (ALS 450) for maximum rigidity and precise directional control.

 

The fully adjustable suspension of the Multistrada 1100 features Marzocchi forks at the front with upside-down 43 mm stanchions. Adjustments for hydraulic compression and rebound damping as well as spring preload are standard.

The Sachs rear monoshock is equipped with a practical hydraulic remote control to adjust spring preload, which operates through Ducati’s rising rate linkages.

The Multistrada is equipped with an exceptional braking system; two 320 mm semi-floating discs at the front wheel with two 4-piston Brembo callipers, while rear stopping power is provided by one 245 mm disc with one Brembo 2-piston calliper.

 

Starting with Model Year 2007 the entire Multistrada family benefits from new vibration-isolated handlebars, which through a pair of silent blocks contained in the specially-designed steering head increases rider comfort.

Engine

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).

The camshafts are supported on oil pressurized plain bearings, which reduce the overall dimensions, the weight, and the number of moving parts, while also improving heat dispersal. The new configuration also puts the camshafts in a more direct relationship with the valves, reducing friction and stress on valve components and thus increasing reliability. In fact, although the cylinder head is more compact, it allows more space for the intake and exhaust valves, these being 45 mm and 40 mm in diameter respectively. Further innovations include valve seats made of beryllium bronze, a technologically advanced material that affords better heat dispersal and wear-resistance and thus maintains valve clearances more accurately over a longer period of time.

To guarantee high mid-range performance, the crankshaft, cylinders and pistons have been designed to obtain a bore and stroke value of 98 mm and 71.5 mm respectively. The pistons are fitted with nitrided steel rings, which afford improved sealing and significantly reduce oil consumption. The connecting rods are made from a new material composition (30NiCrMo4) that has exceptional flow characteristics during forging. In cross section, the new rods are thinner side-to-side, but wider fore to aft, increasing strength and lowering weight for increased reliability and performance.

The crankshaft is of a more compact design and the oil passages have been strategically repositioned in areas less critical for its structural strength. The result is a crankshaft that is more rigid and with less flex, making for less vibration and improved reliability

The 1100 Dual Spark engine also features a new ‘wet’ clutch that has lighter lever effort, is quieter and more modular than a dry clutch and is characterized by having exceptional wear-resistance.

Thanks to an excellent compromise between performance, reliability, noise and lever effort, this clutch is ideal for sports riding and at the same time offers ensures a more progressive action and feel.

The overall look of the engine is characterized by injection-moulded timing belt covers in black, high mechanical and thermal resistance plastic. The engine covers are in a new dark grey colour.

Starting with the entire 2007 range Ducati has introduced a new maintenance programme in which servicing intervals have been extended, and less parts are required and fewer operations are performed, thus reducing the bike’s overall running costs by up to 50%.
