EICMA: Moto Guzzi Stelvio
With the much-anticipated Stelvio
powered by an impressive "quattrovalvole" engine, Moto
Guzzi offers its response to the challenge in the road-going
maxi-enduro sector. This new machine is characterised by innovative
technical and stylistic solutions that place it firmly in the
lead in this category.
Moto Guzzi has carried out a full scale development project and
reconfigured the "Quattrovalvole" engine. The exhaust
system was renewed, then to tuned to "balance" with
the new injection and intake set- ups. These modifications kept
the power output in excess of 100 CV, but, at the same time,
allowed smoother, more controlled delivery at low and medium
revs.
The engine also plays an important role as a stress bearing component
in the new frame. This high tensile steel tubular twin cradle
has been strengthened at the steering head and at the four engine
mounting points.
The machine now boasts a slimmer, more tapered profile. Moto
Guzzi's maxi-enduro is one of the most compact machines in the
sector and introduces numerous technical solutions and new items
of equipment. These include tubeless spoked wheels, anodised
finishings, upside-down 50 mm forks with support brackets for
radial caliper brakes and the magnificent satinised aluminium
exhaust silencer. Riders can now enjoy a adjustable saddle, adjustable
windscreen and stow small objects in a new compartment alongside
the tank. This compartment can be unlocked from a button on the
handlebars.
As far as looks go, the front view of the Stelvio makes it stand
out immediately from other Maxi Enduros. Two powerful round headlamps
that are embedded in the nosecone dominate the front that tapers
gracefully back to blend perfectly with the lines of the tank.
The Stelvio will be available from the end of the year in white
and red and black colour schemes. A version with ABS will also
be available.
IN FRONT, WHATEVER THE ROAD.
The new Moto Guzzi Stelvio completes the range renovation programme
that, in little over 24 months, has seen this legendary marque
regain all its past splendour.
What was missing and what the public were impatiently waiting
for now is now available in the form of a complete motorcycle.
This is the Italian answer to the demand for a multi-purpose
maxi-enduro machine that can adapt to all conditions and restore
the pleasure of riding.
A machine with these characteristics could not have been a descendant
of previous models but was created as part of a totally new project.
It is the direct result of a long and painstaking research and
development programme that involved countless riders of all types
and widely differing conditions of use. Moto Guzzi undertook
this challenge with one particular key element already decided
upon: the new "Quattrovalvole" engine.
Docile and powerful at low and medium revs, this twin-cylinder,
single raised cam transverse unit is housed in a slender tubular
frame that appears so fundamental as to make even specialists
in off-roading look again. Riders will appreciate the absorption
characteristics of the 50 mm upside-down forks and the traction
offered by the combined action of the rear single swingarm and
the progressive rear suspension system, not to mention the superb
CA.R.C (reactive shaft drive) final drive. If the fact that the
Stelvio is very much at its ease on deceptive surfaces with little
adhesion is down to the superb frame design, its decreased weight
and smooth power delivery; its vocation as a tourer is highlighted
in the many little details that were specifically included to
make daily use sheer pleasure. The windscreen and saddle can
be adjusted, side bags come as standard and the pillion passenger's
part of the saddle is more than comfortable in both size and
shape.
A small storage compartment that can be unlocked from the handlebars
has been positioned between the screen and tank. It is the little
details that make all the difference and make riding this machine
such a pleasure. With over 100 CV on tap, the machine offers
superb performance while the sound it makes says it all. It goes
without saying that safety is at the forefront with powerful
radial brake calipers housing twin parallel pistons. Besides
this Moto Guzzi Maxi-Enduro's performance and technology, there
is another element that sets it apart from the competition: its
beauty. The Moto Guzzi Stelvio captivates with its front end
looks and slender profile. The aggressive Guzzi red or sophisticated
white colour schemes catch the eye and are set off by the anodised
tubeless spoked wheels.
