September 13, 2006 Ducati has revamped its popular Multistrada model, pumping the capacity to 1100cc for the 2007 model year and breaking the one litre capacity with its L-twin Desmo motor for the first time. For 2007, the Multistrada features a potent new 95 bhp (up from 92 bhp) engine with a capacity of 1078 cc (up from 992 cc) of the previous version and 10.5 Kgm (up from 8.5 Kgm) of torque at 4750 rpm (max torque was at 5000rpm on previous model). Apart from a fatter mid-range with 20% more grunt, the new engine has a quieter, more robust wet clutch, vibration-isolated handlebars, and a new maintenance program that reduces running costs by as much as 50%. The Multistrada will also be available in an S version with the same powerplant and fully-adjustable Ohlins suspension derived from the Ducati Superbikes. The changes to the Multistrada will make an incredibly versatile machine even more adaptable to any road condition. On mountain roads it offers impressive cornering performance by way of Superbike-grade suspension, world-class brakes and the renowned Ducati Trellis frame. For long journeys, the longer travel suspension smoothes the way, vibration isolated handlebars reduce fatigue and the relaxed riding position optimises comfort for both rider and passenger. In town the agile chassis, wide bars and broad power of the new 1100 engine make crossing busy city traffic an adventure to look forward to.

Multistrada 1100

The new Multistrada 1100 widens the horizons of all those who are ‘sport motorcyclists’ at heart but still want a bike they can use seven days a week. Riding a Multistrada makes every road a thrill. The punchy new 1100 Desmo L-Twin engine delivers smoother, more tractable power delivery and, coupled with a refined chassis, delivers confident handling and optimal comfort, even over long distances.

The unmistakable Ducati Trellis frame combines with fully-adjustable suspension to adapt the bike to any road condition and every riding style, while rider comfort has been further improved with new vibration-isolated handlebars.

Superb road holding, a powerful new 1100 engine and all day comfort gives the versatile Multistrada a unique personality and character in true Ducati style.

The 1100 is the latest evolution of the Multistrada concept, introduced by Ducati at the start of 2003. It contains all of the innovations that helped to make the model a true point of reference for a totally new market segment.

The characteristic two-part nose fairing, with a transparent screen that moves with the handlebars, allows better than average steering manoeuvrability. The unique tank and seat assembly comes from a single moulding and provides a fuel capacity of 20 litres; one of the innovations on the Multistrada 1100 is the inclusion of a fuel reserve sensor. The joint action of the fuel level gauge and the new sensor guarantees a reliable and constant indication of the amount of fuel remaining in the tank at all times.

Two display management functions are new features on the 1100 model: trip fuel and auto ‘light off’ system. The former is an additional trip meter that is activated when the fuel reserve light is on, while the latter is a feature that automatically switches off the lights after 60 seconds of key-on if the engine is not running.

Other style features of the Multistrada that remain unchanged on the 1100 version are the front headlight cluster, the single-sided aluminium swingarm, the tail section and the aggressive exhaust unit.

Like the rest of the 2007 range the Multistrada 1100 fully complies with EURO 3 exhaust emissions: the lambda probe inside the muffler unit combined with a three-way catalytic converter ensure maximum efficiency. The function of the lambda probe is to detect the amount of oxygen present in exhaust gases and gauge the fuel mixture. In this way the oxygen concentration through the catalytic converter allows the correct chemical reaction and the three-way converter oxydizes the unburnt hydrocarbons and carbon monoxide and reduces the nitrogen oxides.

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%.

Multistrada 1100 S

Due to its world-class suspension and componentry level, this version is for those riders who demand the ultimate in sports performance. It is based on the Multistrada 1100 but features a number of components derived from the Ducati Superbikes, including fully-adjustable Öhlins suspension and carbon fibre highlights.

The Multistrada 1100S is to all intents and purposes a production special, a bike that is capable of highlighting the sporting characteristics of a model whose winning feature is its versatility.

The 1100 features a number of racing components including a front mudguard and cam belt covers in carbon fibre, as well as exclusive variable-section alloy handlebars, which from this year are fitted with vibration isolator mounts. The prestigious Öhlins suspension, derived from the Superbikes, bring clear benefits in terms of superior road handling as well as an exclusive quality look.

Chassis

The chassis is the same as the one that has always given the Ducati Multistrada its extreme versatility and all-round performance and the Multistrada 1100 S earns its ‘S’ status by adding sophisticated suspension and a sporting set-up to an already high performance motorcycle. It provides true superbike performance and is capable of lightning-quick cornering and extreme riding precision.

At the front 43mm Öhlins forks with low friction TiN fork sliders, adjustable in hydraulic compression, are complemented by a fully adjustable Öhlins rear shock with remote preload adjuster for Superbike-class road holding.

The Multistrada 1100 comes with red fairing and red frame, while the Multistrada 1100 S comes in the same colour scheme plus a black fairing and black framed version.
