Special Report - Edited by
The New Moto Guzzi Stelvio!
on a North American Stelvio!
The Moto Guzzi Stelvio, cousin to the Moto Guzzi
it?), is ready for market and will be sold by
Moto Guzzi dealers worldwide in 2008. The bike
was announced at the EICMA show in Milan in November
The Stelvio should make a nice competitor for the
BMW R 1200 GS Adventure Tourer, and although the
styling of both is something of an acquired taste,
the Stelvio has a modern, hard-edged look that also
seems "tight", without all the "loose ends" that
seem to hang off BMW's big guy.
The turn signals on the Stelvio are nicely
integrated, and the bike supposedly has fittings for
saddlebags (panniers) designed right in to the frame
in the rear, which is a nice touch. The top
box rack appears to be standard, and many other
accessories should also become available.
Note also the Stelvio's two-piece seat, which may
indicate the possibility of lowering or raising the
seat for the rider. The passenger seat looks
The Stelvio's engine is the new Moto
Guzzi 8-valve 1200cc engine, also used in the new
Griso (Thanks to S.B for this info!).
The bike uses upside-down forks and radially
mounted front brakes. The front wheel is a
nice 2.50" x 19" Excel spoked job fitted with a
110/90 ZR19 tire and the rear is a 5.50” x 17”
fitted with a meaty 180/55 ZR17”. It appears
that Pirelli Scorpion Sync tires are used.
Here's more information from the Moto Guzzi press
release and some photos and a table of technical
data from Moto Guzzi. Also, be sure to read
overview on the other new 2008 Moto Guzzis. Enjoy!
Moto Guzzi Stelvio 1200 4V
The Stelvio Pass is a winding path that like a
snake coils up shrouded by the shadow of the
Ortles massif, strangling it with 84 hairpin
bends that link, at an altitude of 2758 meters,
Valtellina with Venosta Valley. For
riders, but not only for them, this asphalt
stretch built in 1855 is a legendary route that
combines the difficulty of a rugged track with a
massive natural beauty, resulting in a riding
experience of extraordinary intensity.
For Moto Guzzi, it is a
historical test stretch, where the benefits of
chassis features chosen, resistance and
decelerating power, engine response and
suspension absorbing capacity can be tested.
A frequent test bench where the new Mandello's
creature, taking its first steps, caused instant
astonishment due to its dynamics and the
pleasurable ride offered.
So much so, that it seems quite
natural to summarize the design talent and
technical intuitions instilled in the new maxi-enduro
by Moto Guzzi, with the images and sensations of
a place, where the riding pleasure is enriched
by the feeling of adventure, sport challenge,
extreme tourism: the Stelvio Pass.
Moreover, the new Moto Guzzi
Stelvio 1200 4V has been designed and developed
to brave any destination, devouring kilometers
of roads and even off-road surfaces. This
multipurpose capability is evident at first
glance .Inspired by off-road bikes, Stelvio 1200
4V breaks the traditional, austere look of
models in this market segment by introducing new
intense shapes and a dynamic energy that evokes
the feeling of adventure, long routes, the most
Slender and streamlined in the
lower part, highlighted by refined aluminum
spoke wheels and the technology seen in the
powertrain and final transmission, the Moto
Guzzi Stelvio 1200 4V is compact and robust in
the upper part, revealing the care taken to
obtain the best ergonomics for the rider.
They are sculptured shapes that
stress the numerous design details to respond to
an active and intense use, such as the presence
of a powerful double front headlight assembly,
the windshield and the adjustable seat, the
ample section of chassis guides, the aluminum
exhaust silencer, the careful assessment for
passenger and luggage transport.
This design concept has been
designed to stress the throbbing heart of
Stelvio 1200 4V, the unmistakable 90°
transversal V-twin engine in its most functional
“quattrovalvole” (four valves) version.
Strong, powerful, dominant in its action,
Stelvio 1200 4V is now streaking along European
roads in three different color concepts: red
Corsa for the classic sportsman; Black Guzzi for
those who prefer tradition, and Lunar white, the
most glamorous color of the moment.
Stelvio 1200 4V marks the return of Moto Guzzi
to the Maxi-Enduro segment, a motorcycle concept
developed on the echoes of the great popularity
of African marathons. An austere
motorcycle, dominated by impressive tanks
strongly integrated to the fairings that extend
until the engine is almost hidden, by the
undoubtedly fascinating as well as irrational
image when adventure does not have the equator
as its horizon, but just crossing an urban
centre or riding along main roads leading
towards weekend or holiday destinations.
Starting from this premise, Moto
Guzzi has developed a stylistic idea as a
countertrend, highlighting the dynamic energy
expressed by the mechanics and the chassis at
sight, with tight-fitting panels, with clean
cuts and sharp lines, able to give the vehicle a
sensation of lightness and power, in an ensemble
of solid elegance and class.
Stelvio 1200 4V immediately
captivates with its front end look- two
side-by-side headlamps with convex lens create a
three-dimension effect that makes the machine
look compact, also helped by the effect created
by the satin reinforcement in anthracite color.
This solution is also applied to the mudguard
and tank rear, which not only creates an
original aesthetic design but also protects
surfaces from gravel as well as reinforces the
image of a vehicle resistant even under the most
The light fairing emphasizes
numerous prismal elements and concave surfaces,
and a careful aerodynamic study is perceived at
the assembly formed by the adjustable shield on
the top fairing plus the contoured but capacious
tank. An evident characteristic in the
front view is the predominance of two auxiliary
air deflectors highlighted with silver paintwork
and metal louvers, designed to direct fresh air
The top fairing, matching the
double headlight assembly parabolas, forms a
shape that deviates the aerodynamic load when
riding at high speeds. The peculiar blow
molding technology was used to produce the tank
and helps to minimize dimensions and weight
according to the (18-litre) capacity.
Moreover, it includes a
fantastic glove-box that can be unlocked from
the handlebar and is atop the saddle, which, by
covering the grooves, avoids direct contact with
the rider's legs to ensure superior riding
Once you are seated on the
saddle, finely upholstered with non-slip
material, it is quite noticeable there is more
space for both rider and passenger's comfort.
The rider saddle height can be adjusted to two
positions, 820 mm or 840 mm from the ground,
whereas the passenger, besides being seated on a
thick and spacious seat, can count on a solid
and comfortable handhold seat strap.
Even more aggressive from the
forecarriage, the rear end look is dominated by
the hi-tech aspect of the rear light with
complex surface curve and LEDs, and by an
important enhanced aluminum double tail silencer
that evokes solidness and power.
Stelvio 1200 4V is a tourer, that can also be
used off-road, and with excellent performance on
asphalt. These characteristics emerge
immediately once you are seated on the bike,
where the perception of carefully-designed
ergonomics can be felt straightaway: saddle,
footrests and handlebar form a perfect triangle
for all users.
Moreover, for the
perfectionists, there is still room for minor
adjustments: windshield, saddle height (820 or
840 mm), handlebar inclination, levers, pedals,
also for professionals, set screws to adjust
hydraulic compression/rebound damping of
In a matter of seconds,
everything is at the right place to face any
challenge, from city traffic to the most
inaccessible off-road paths. In motion,
reduced vibration and an efficient aerodynamic
protection ensure riding comfort for rider and
passenger as well, ideal to tackle long trips.
Among the most appreciated
features for everyday use, there is a glove-box
to the left-side of the tank that can be
unlocked from the handlebar and even, if your
are wearing gloves. The instrument panel
features complete and easily visible gauges- a
white-background rpm indicator that incorporates
efficient service warning lights, long range
lights (optional), and a dash display that
provides plenty of information about the vehicle
operation and diagnosis, a fuel level indicator,
average and current consumption, average speed,
trip time, maximum speed peak reached and, as
heated handgrips may be fitted upon request, the
heating level of handgrips can also be seen.
The Stelvio 1200 4V is a class
leader, as a result of an elegant aesthetic
appearance, is also enhanced by features which,
while fulfilling a stylistic function, set new
parameters in terms of effectiveness and safety.
Some examples are the headlight
assemblies, highly reliable and effective,
manufactured with technology borrowed from the
automotive industry, fittings for the panniers
are integrated to the passenger handgrips and
the luggage racks, design elements expressing
the versatility and calling for adventure and
touring of the Stelvio 1200 4V model.
You should not be mislead by its luxury
off-road appearance: the Stelvio 1200 4V
features driving effectiveness superior to the
average of many road motorcycles, since it is
equipped for the unexpected and able to
withstand any off-road driving strains.
The secret is the new upper twin
spar frame, made of high-strength steel, with
2.5mm thick directional tubes, where the engine
is anchored through six connecting points, two
more than in usual frames, which give high
rigidity to the assembly at twisting moments.
Chassis positions have been
defined to facilitate handling, a headstock with
a 27° inclination for a 125mm trail, improved by
a 1535mm wheelbase which guarantees impeccable
Suspensions, pieces of fine
workmanship adjustable not only during
preloading but also for the hydraulic response
at compression and rebound damping, offer an
immediate and clear response to handlebar
pressures. The front end is controlled by
a solid upside-down Marzocchi fork, with 50mm
and 170mm travel stems, whereas at the rear,
suspension kinematic mechanisms with progressive
rising rate are moved by a Boge unit that works
on a 155mm stroke.
The refinement of the suspension
department guarantees a neutral setting at all
times. When going out of a bend, and the
action of the 105 horsepower generated by the
new “Quattrovalvole” engine is requested, or
when braking, under the quick deceleration
generated by the three-disc Brembo braking
And either for its effectiveness
or its aesthetic value, there stands out a
system consisting of radially-mounted calipers
engaging onto a couple of fully drilled discs
for better heat dissipation.
Splendid spoke wheels assembled
with Ber rims and Alpina spokes at Moto Guzzi
are ideal for Pirelli Scorpion tubeless tires.
They are 110/80, on a 19-inch front wheel and
the 180/55/17 oversize for the rear wheel, which
guarantees a truly sporting supporting surface.
Even when considering chassis
elements, where the overall assembly is what
really counts, Stelvio 1200 4V is not afraid of
Engine and Transmission
(See below for chart). Stelvio has been
developed with the new “Quattrovalvole”, the
most advanced evolutionary milestone of the
mythical 90° transversal V-twin engine. An
engine that has evolved beyond recognition even
for the most loyal passionate, and that marvel
due to its contents and performance, the highest
of the category.
A design that has absolutely
revolutionized Mandello's twin-cylinder
mechanics, with more than 75% of new components.
In all, 563 new parts have been designed to
allow this 90° V-twin engine to have a single
overhead camshaft distribution system, which
controls 4 valves per cylinder.
A great example of mechanics,
unique in the motorcycle panorama thanks to its
lucid design structure, obtained by light and
smooth sliding masses, moving alternately, the
thermodynamic study and fuel supply in order to
enhance functions, reliability and smooth
operation aiming at a new quality standard.
The new lighter crankshaft,
3-ring forged pistons and very light valves with
5-mm stems supported by cone-section springs
that eliminate resonance and power losses at
high speeds, emerge among the most valuable
Lubrication and cooling are
ensured by two pumps fitted in tandem in order
to obtain smaller dimensions and are activated
by three gears that make lubricant flow along a
channel, separated from the cylinder head, to
reach the exhaust pipe, where the highest
temperature is found, and feed cooling jets
placed under the piston.
In order to house these new
components, a completely new crankcase is
necessary, to offer smaller dimensions and an
integral front bench support with bushing, while
the rear one has a new flange and a more
effective oil feeding system.
The most seducing element of the
new “Quattrovalvole” is, surely, the modern
design of cylinders, more compact with cooling
finning oriented to riding direction.
Consequently, head covers have been redesigned
by adding, apart from the “Quattrovalvole”
identifying abbreviation, a floating system that
further cushions the silent action of the
distribution system, controlled by “Morse”
chains and supplied with hydraulic tensioners
and tensioning pads.
Fuel supply has also been
subject to important innovations, with throttle
bodies well over Ø 50-mm and new IWP 189
In the Stelvio configuration,
the Quattrovalvole receives an original exhaust
system which, thanks to the increase of the
silencer internal volume, made in aluminum,
optimizes the engine performance at low and
average speeds, generating a maximum power of
105 CV at 7500 rpm and a 11 kgm torque at 6400
rpm. These numbers offer a clear idea of the new
Stelvio 1200 4V potential.
