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%.
