2012 Moto Guzzi Stelvio 1200 8V-NTX
Named after the famous Alpine pass that
connects Valtelline Valley to Vinschgau Valley with
84 amazing s-bends between them, Stelvio has launched
Moto Guzzi back among the stars of the maxi enduro
world. A highly appreciated bike that has now reached
a coming of age at a technical-functional level, thanks
to the updates and final tweaking undergone by the
new 1200 8V and NTX.
It all starts with style, now even
more attractive and trendy rounding off the fuel tank
by integrating it within the lightweight fairing,
which now highlights a clearly smooth streamlined
effect which flows into the double front headlight
assembly. The latter feature is a distinctive element
of the Stelvio design, and the only detail inherited
from the previous version. The top fairing, windshield
and the half-fairing with integrated turn indicators
are all brand new elements that combine to give the
front-end of the Stelvio 8V a cutting-edge, more aggressive
and dynamic look. It has an original design, but it
is above all more functional and versatile, features
that are of uppermost importance on models of this
type. From an objective standpoint, the style of the
new surfaces emphasises two fundamental project milestones
compared to the previous version: more efficient aerodynamic
protection, thanks to the new top fairing and practically
twice fold range capacity thanks to the outstanding
new fuel tank with a 32 litre record capacity.
This new Stelvio bike has an air of
complete renovation about it, fine examples being
the cockpit with brand new graphs on the on-board
control panel, a new increased scale fuel indicator.
The heart that beats inside this touring
bike is the renowned V-shaped 90° transverse twin-cylinder
"Four valve" engine, the highest performer
among all the families of engines manufactured at
Mandello del Lario, which has now reached exclusive
levels as far as its technical/performance development
This latest version can boast the careful
attention paid to achieve a more silent and smooth
running of the engine, whilst tweaking the electronic
control, timing system and cooling system. The brand
new integrated ignition and injection ECU now exploits
the signals sent by the two lambda probes to guarantee
adequate feeding throughout the entire combustion
cycle, improving response to the throttle control,
low-to-mid-range power delivery further to consumptions
and emissions. The ECU also includes the ATC system
to prevent sliding: this system controls ignition
advance and injection to cut torque delivery whenever
a sudden loss of grip is detected so as to help the
rider to remain in control under extreme, unexpected
conditions. The system can be deactivated, just like
The engine now boasts a maximum torque
of over 113 Nm delivered at a mere 5,800 rpm and easily
reaches a peak in output of over 105 HP; it practically
reaches an automobile-level speed of 7,250 rpm.
The NTX is the more “adventurous”
version of the Stelvio, and now has all the technical
features of the base version, plus some exceptional
new fixtures, i.e. the sturdy "armour" that
embraces it and comprises the oil sump guard, engine
guard, cylinder guard, full cover hand-guards and
extra large windshield with additional wind deflectors
to protect the rider and his bike against the hidden
dangers throughout his trip.
A bike dedicated to long haul travellers
naturally needs luggage space, hence the spacious
aluminium panniers and additional halogen lights.
Even more luxury options are available on the accessory
catalogue including a GPS navigator installation kit,
heated hand-grips, CA.RC protection (Compact Reactive
Cardan Shaft Drive), aluminium top box for the NTX
or side wind deflectors, extra large windshield, dedicated
body coloured plastic polymer panniers and top box
kit for the 1200 8V version.
The new Stelvios are available in Guzzi
Black, Moon White and Sienna colour schemes, while
the NTX will flaunt a brand new colour concept on
a black satin finish base (Lava Black).
Unstoppable long-time tourers.
Stelvio 1200 8V and NTX are great tourers 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, as well as race-style adjusters for hydraulic
compression/rebound damping. In a few 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 the efficient aerodynamic
protection offered by the new top fairing and windshield
and original side wind deflectors (dedicated for NTX)
ensure riding comfort for rider and passenger as well,
ideal to tackle long trips.
Major improvements are also found in the controls,
with a new dashboard including a 12V power outlet,
a new fuse box compartment, cockpit and instrument
panel with new rpm indicator graphics and a dash display
with six-mark fuel indicator that integrates with
on-board computer functions such as average and current
consumption, average speed, trip time, maximum speed
peak reached and diagnostics. The display also lets
you control hand grip heating (option) and activate
the ATC system, fitted as standard on both models.
CHASSIS, SUSPENSION AND BRAKES
Designed for non conventional paths.
You should not be mislead by its luxury off-road
appearance: the Stelvio 1200 8V and NTX feature driving
effectiveness superior to the average of many road
motorcycles, since they are 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 1535-mm wheelbase which
guarantees impeccable steering precision.
High quality suspension whose adjustable preload
and hydraulic response during compression and rebound
combine to ensure instant, smooth response to pressure
on the handlebar. The front end is controlled by a
new upside-down Marzocchi fork, with 45mm stanchions
and 170mm travel, whereas at the rear, suspension
kinematic mechanisms with progressive rising rate
are moved by a Sachs 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 system
supported by the deactivatable Continental ABS, fitted
as standard on NTX and Stelvio 1200 8V. Both sport
a new couple of 320mm front brake discs with a new
holder flange, while retaining a 282mm brake disc
at the rear. Innovation also for the wheels which
boast a cutting-edge designed set of light alloy rims
with 150/70-17 rear tyre, new on the 1200 8V version,
previously exclusively mounted on the NTX, which comes
standard with tubeless spoked wheels (patented Alina
ENGINE AND TRANSMISSION.
The “Quattrovalvole” evolution
The Stelvio 1200 8V and NTX boast the latest evolution
of the "Quattrovalvole" engine”, introduced
in 2006 and universally acknowledged as the most advanced
version of the V-shaped 90° transverse twin-cylinder.
This highly sophisticated mechanical gem, which is
unique in terms of both architecture and engineering
clarity, is built using advanced componentry and technical
solutions. Worth mentioning are the raised cam profile
single camshaft timing system driven by silent "Morse"
type chains” with hydraulic chain tensioners,
the forged pistons with three rings cooled by oil
jets in the crankcase, the ultra-light valves in special
alloy steel with 5mm stems, and the conical valve
springs that eliminate resonance and power loss at
high engine speeds. Lubrication and cooling are ensured
by two coaxial pumps that circulate lubricant through
a separate duct in the head up to the exhaust valve
seats, where the highest temperatures develop. The
cylinders feature an extremely modern design, with
the cooling fins tapered toward the front of the cylinders,
while the valve covers - which proudly flaunt the
“Quattrovalvole” moniker - feature a floating
mounting system to reduce mechanical noise.
As far as the fuel system goes, the "Quattrovalvole"
engine premiers the new Marelli IWP 189 injectors
located on the intake ducts of the sizeable 50mm throttle
bodies, whereas the brand new integrated ignition
and injection ECU now exploits the signals sent by
the two lambda probes to guarantee adequate fuel metering
throughout the entire combustion cycle, improving
response to the throttle control, mid range power
delivery further to consumptions and emissions. In
terms of electronic components, the new Stelvio 1200
8V and NTX debut the ATC system to prevent sliding,
an invaluable help in keeping out of trouble in poor
The gearbox is a genuine six speed mechanical gem
that excels for quietness, an easily selectable neutral
position and precision, thanks also to the quiet and
smooth single plate clutch.
