2009 Aprilia Dorsoduro 750
Developed in close collaboration with Aprilia Racing
(the department of Aprilia responsible for thirty-seven
world titles), the Dorsoduro 750 combines the best
technology from the worlds of supersports and racing
supermotards. The result is a distillation of performance
and technology, a special, extreme, and elite motorcycle
that is capable of elevating its rider to motorcycling
The lightweight, agile, and powerful Dorsoduro 750
is driven by a new generation of engine incorporating
the most advanced technical solutions found on any
bike of its kind. Thanks to advanced electronic engine
management, Aprilia’s compact 90° V twin
delivers superb performance, well beyond the reach
of its rivals. Specific power is 122.6 HP/litre and
maximum torque is 82 Nm at only 4,500 rpm.
As you would expect from Aprilia, the chassis is
unique in the supermotard segment. Having achieved
amazing results on the super-specialist SXV, Aprilia’s
mixed trellis and aluminium frame is now one of the
most distinctive features of the Dorsoduro, giving
it the sort of directional control, responsiveness
and precision the competition cannot hope to achieve.
Despite its essential design, the Aprilia Dorsoduro
boasts the highest level of components, technical
equipment and finish. Four piston radial calipers,
wave discs, a hydraulic wet clutch, adjustable front
and rear suspension, Tri-Map ride-by-wire engine management
and a Matrix instrument display with on-board computer
are just some of the many items that make the Dorsoduro

Design: Conceived To Thrill
The minimal and aggressive bodywork of the Aprilia
Dorsoduro 750 adds the perfect finishing touches to
the advanced motorcycle technology that forms the
basis of its design. The Dorsoduro 750 is built around
the rider. That is why, on this radical, daring and
sporting machine everything contributes effectively
to maximum riding pleasure. Plastic body panels have
been reduced to a minimum for this very reason. As
with top competition machines, anything that does
not improve performance has been eliminated. Only
the place for a number has been left to emphasis the
bike’s close ties with the world of racing.
The middle of the bike, the area most important
to rider movement under competitive riding conditions,
shows just how compact this design really is. The
Aprilia Dorsoduro 750 is incredibly slender and agile
and enters into instant symbiosis with its rider.
Only a few metres on this amazing machine are enough
to feel completely at one with it. Aprilia’s
design team have achieved this impressive result by
giving the Dorsoduro a long, flat seat, derived directly
from the world of racing, allowing the rider to find
the most effective position at all times.
The sleek, compact tail houses a twinned exhaust,
a solution that not only gives the bike a mean, aggressive
look but also achieves perfect symmetry and ideal
weight distribution. The hand guards are derived from
those of the SXV supermotard and, despite their streamlined
look, offer effective protection against accidental
impacts with the control levers.
Engine: A State-Of-The-Art Twin
Numerous improvements have been made to the Aprilia
750 cc, 90° V twin engine, which now features
mapping specially developed to bring out the Dorsoduro’s
Improvements have been made to various areas of
the 749.9 cc engine with its bore and stroke of 92
x 56.4 mm. As a result the electronic and mechanical
content of this V twin engine sets new standards not
only for engines of this size but for many far larger
The electronic engine management on the Dorsoduro
750’s engine leads the field in technology and
performance. The Dorsoduro features a second generation
electronic throttle with Tri-Map selectable triple
Three performance modes, Sport, Touring and Rain,
can be selected from a switch on the handlebars (with
the throttle closed for safety reasons). The Dorsoduro
changes its character radically, depending on what
mode you select. Sport mode gives you aggressive instant
power; Touring mode gives you a smoother action, better
suited to relaxed long distance riding; and Rain mode
gives you ultimate safety slippery surfaces.
The Tri-Map electronic throttle also means smoother,
more consistent power thanks to more accurate and
precise throttle control based on parameters including
engine speed, gear selection, air flow, throttle position
Whatever mapping you select, the engine is always
ready to deliver the best possible performance in
terms of acceleration and rev range, giving you an
amazingly satisfying and entertaining ride.
The exhaust is made entirely from stainless steel.
The collector pipes meet in a single silencer under
the seat before splitting again into two tail pipes.
The large volume of the exhaust system also aids engine
breathing and boosts efficiency.
Thanks to its advanced electronic and mechanical
technology, the Aprilia V twin engine develops 92
HP at 8,750 rpm and a maximum torque of 82 Nm at 4,500
rpm. These figures enable the Dorsoduro to compete
directly with motorcycles powered by far bigger engines.
The Aprilia Dorsoduro 750 is also available, right
from its introduction, in a restricted 25 kW version.
The use of a ride-by-wire electronic throttle has
allowed Aprilia to avoid cutting power right across
the range, as happens with less advanced restricted
versions. Instead, the power curve of the restricted
Dorsoduro is identical to that of its full-power sister
right up to the point where the permitted power limit
is reached. The 25 kW Dorsoduro 750 therefore delivers
far superior acceleration to the equivalent models
of the competition, to the benefit of riding satisfaction
Frame: Perfect Balance
Aprilia motorcycles have always been acclaimed for
the excellent chassis designs. The Dorsoduro 750 is
no exception, thanks to a chassis that makes it the
best balanced and most effective bike of its type.
The new Dorsoduro is easy and intuitive to ride despite
its blistering performance. It is designed to be ridden
at the limit under all conditions, to perform extreme
power slides, and to blast out of bends under full
power. The secret lies in an ultra-responsive chassis,
whose ergonomics suit riders of all statures and allow
you to “take it to the limit” and enjoy
the thrills of a motorcycle built for pure entertainment.
The frame incorporates all of Aprilia’s vast
racing experience, and makes full use of the latest
mixed steel and aluminium designs derived from the
world of Supermotard World Championship racing. The
top half of the frame is a tubular steel trellis.
This is secured to generous aluminium side members
by special high strength bolts. The resulting structure
is extremely rigid and lightweight, and provides the
best possible means of harnessing the exuberant power
of the Aprilia V90 engine while still communicating
a strong impression of lightness, high technology
and Italian style.
Continuous co-operation between engine and frame
designers has led to the perfection of high-tech,
performance-oriented solutions and to total integration
between engine and frame. The intelligent design solutions
applied to Aprilia’s V twin engine have made
it shorter than ever, permitting the development of
a rational and efficient frame and a superbly agile
and incredibly responsive motorcycle.
The lateral position and acute angle of the rear
monoshock has freed up the space needed to ensure
optimum exhaust geometry without any increase in the
bike’s overall length, and without subjecting
the monoshock to thermal stress. The aluminium swingarm
is robust enough to withstand the asymmetric stresses
generated by the lateral positioning of the rear suspension.
The swingarm has been specially developed to satisfy
the needs of a supermotard like the Dorsoduro 750,
and combines excellent torsional rigidity with the
elasticity needed for precision under acceleration
and intuitive control under changing conditions.
Suspension: Effective On All Surfaces
Optimum suspension setup has always been one of
the strong points of the Aprilia design and testing
team. The 43 mm upside down fork features shell-cast
bottom outers with radial calipers mountings, and
offers adjustments for spring preload and rebound
damping. This sophisticated fork offers a superb sliding
action and a wheel travel of 160 mm in line with the
latest trends in supermotard racing. Both yokes are
forged, and the top yoke is also anodised to match
the Dorsoduro’s high level of finish.
The laterally offset monoshock pivots directly on
the swingarm in a cantilever configuration, and is
also adjustable in spring preload and rebound damping.
Rear wheel travel is 160 mm, again in keeping the
requirements of a top level supermotard, on which
effective, controlled long stroke suspension is a
Brakes: Racing Technology
The Aprilia Dorsoduro 750 is equipped with the best
braking technology currently available. The front
brakes feature 4-piston radial calipers, state-of-the-art
for the motard market. The lightweight, 320 mm wave
discs ensure shorter than ever stopping distances.
The bike’s aggressive stopping power is emphasised
by the mean look of the braking system, in keeping
with the Dorsoduro’s overall styling.
The rear brakes incorporate another wave disc, 240
mm in diameter this time, plus a single piston caliper.
Both the front and rear brakes are fitted with aeronautical
type metal braided brake lines to eliminate the sponginess
associated with conventional rubber hoses and to deliver
maximum braking precision.
A sophisticated two channel Continental ABS system
provides maximum active safety on the Dorsoduro 750.
The ABS controller is specially calibrated to make
full use of the Dorsoduro’s impressive braking
power and tyre grip on dry surfaces. Riders can therefore
still enjoy this amazing “fun bike” to
Supermotards are always no-frills machines, and
sometimes quite spartan. This, however, does not mean
having to do without top quality components and attention
to detail. Here too Aprilia stands apart from the
competition by adopting a level of equipment worthy
of a true market leader:
- Matrix instrumentation. The mixed analog/digital
instrument cluster receives data over a CAN line
and incorporates a memory that forms an integral
part of the diagnostics system. The ultra-compact
instruments feature a modern design and are extremely
light in weight. All functions can be accessed and
controlled from the handlebars. The LED backlighting
is white in the analog area and red in the digital
area, and can be adjusted to three levels of brightness;
- Dual taper anodised aluminium handlebars exactly
like those fitted to Aprilia’s racing supermotards.
This super-lightweight component is specially designed
for optimum dynamic control;
- Hydraulically operated clutch for a consistently
precise action and exceptional smoothness. The clutch
is also self-adjusting and completely maintenance
