2012 Moto Guzzi Nevada Classic &
Anniversario

The single throttle small block engine
now equips the Nevada Classic and Anniversario too.
Increased power and torque, decreased fuel consumption
and emissions and even greater riding pleasure.
1. TECHNOLOGY, PERFORMANCE AND SENSATION
TRANSPLANT.
For more than twenty years the Nevada has been the
entry level model to the Moto Guzzi world thanks to
its ability to reconcile performance and accessible
costs with the image and technology of a superior
class bike.
With its design inspired by the flagship California,
the Moto Guzzi Nevada never gave in to the temptation
to replicate the American inspired ornamental style
so typical of this segment, keeping its design and
technical personality intact.
This is a choice which, together with the superior
road qualities that stem from a faultless chassis,
allowed it to overcome momentary fashion, making it
the most effective proselytism activist toward the
Moto Guzzi world.
In 2010 the Anniversario version joined this role,
the model which celebrates the twenty year anniversary
of the Nevada which, alongside the famous Classic,
introduced a more modern and dynamic style.
Both return domineeringly into the limelight of
the segment with the introduction of the brand new
single throttle small block designed for the new V7
series and extended to the Moto Guzzi custom middleweight
range as well.
Compared to the previous engine, the new single
throttle unit provides a 10% reserve of power and,
above all, engine torque for better fuel economy and
lower emissions. On this type of bike the increase
in performance would quite bland information were
it not sustained by exciting elements of the engine,
such as aesthetics and sound. For both parameters,
the improvement is clear: the new engine has rounded
thermal groups like the Moto Guzzi engines from the
1970s, with more extended finning of the cylinders
which connects to the chromium plated valves cover,
where the 'Moto Guzzi' writing makes its welcome return.
Even the sound, while maintaining the famous pulsation
of the 90° V two cylinder, is clearer, both due
to the revamped thermal part and the new filter casing,
not located behind the throttle body and not in the
middle of the V that the cylinders form.
In addition to the new engine, the two Nevada models
also share the well known chassis, which has not undergone
any changes, confirming for both versions the perfect
double cradle frame with bolted and removable lower
elements. Characterised by a conservative chassis
geometry, with a good headstock rake angle (27°50')
which guarantees reassuring stability and directional
precision. Comfort is guaranteed by quality suspension
components. At the front is a Marzocchi fork with
40 mm stanchions and 130 mm wheel travel, while at
the rear is a swingarm linked to two shock absorbers
featuring adjustable spring preload and offering 118
mm of wheel travel.
The brake system consists of a 320 mm floating front
disc and a 260 mm rear disc. Other standout features
are the spoked wheels, measuring 18 inches at the
front and 17 at the rear to cater to high profile
tyres, for outstanding agility and superlative feel.
2. THE NEW, SINGLE THROTTLE V7 ENGINE.
The original engine design dates back to 1977, the
year of the Moto Guzzi 50's fortunate début.
Since then the engine has been continuously updated,
sustaining displacements of 350, 500, 650 up to 750
cc, going from carburetor to electronic injection,
but staying faithful to the genial layout introduced
in the original design by engineer Lino Tonti. Appreciated
all over the world for its proverbial reliability
and functional regularity, the small block, after
many years, needed a bit more liveliness at high rpms.
And so, the search for greater performance opened
the door to a new design, rich with innovative solutions
that project this engine among the most advanced in
its category with more than 70% new parts, equal to
more than 200 new or redesigned mechanical organs.
This design freshness can already be seen in the
layout of the thermal group which is a summary of
the design philosophy for the entire bike: innovation
which respects tradition. And so it is that the square
finning, legacy of production from the 1980s, passed
the baton to a rounded shape which is reminiscent
of the first generation of two cylinders from Mandello.
The valves cover is also a homage to its two cylinder
origins; made in aluminium, it faithfully covers the
profile of the finning, showing off the Moto Guzzi
signature in bas-relief. Another element which is
immediately recognisable is the disappearance of the
two intake manifolds and relative throttle bodies:
in fact, the new small block is the first single throttle
Moto Guzzi engine.
The manifolds were replaced by a single Y manifold
made of rubber, completely ribbed and straight (diameter
of 36 and 39 mm respectively from the injector groups
and the throttle body) which links to a single Magneti
Marelli MIU3G 38 mm diameter throttle body.
This is a modern unit which allows two lambda probes
to be managed, thereby obtaining a mixture to the
cylinders which is more uniform with consequent improvement
in fuel economy and harmful emissions, besides contributing
to the increase in performance, which was the goal
of the entire design. For this purpose a new head
was designed, working on the intake ducts, now larger
in diameter and better linked to reduce losses and
increase turbulence, as well as repositioning the
spark plug hole more centrally, thanks to the use
of a more modern plug with d=10mm threading and a
prominent electrode.
The squish area and the compression ratio is also
increased, thanks to the use of new, higher performance
pistons which increased the ratio by one point, going
from 9.2 to 10.2. In addition to the pouches obtained
at the top of the piston, the bottom of these are
completely redesigned to make the structure more sturdy
without increasing the weight. The segments are also
new, with more modern sizes, material and shapes,
and they contribute to improving efficiency and oil
consumption.
The general efficiency of the engine stems from
the contribution of the new cylinder finning, greater
dimensions and wheelbase which lowered average operating
temperatures, and the new filter casing, redesigned
to accommodate the "breathing" needs of
the two cylinder from Mandello.
With this new configuration, the two cylinder from
Mandello became significantly more sturdy in engine
torque and above all in maximum power, growing 10%
with higher inclination for spurts and a power curve
which expresses its additional horses already from
3500 rpm.
The transmission has also been revamped, still five
speeds, but with a new pre-selector which has made
control more precise, smooth and quiet.
3. THE NEVADA RANGE:
NEVADA CLASSIC:
This is the custom that retains the design style
and philosophy of the flagship California. From the
time it was introduced in 1990, it was cleverly called
"eurocustom" because, although maintaining
the typical characterisations of this type of bike
such as the low saddle, wide handlebars and the moderately
forward placed footrests, it provides a riding position
which is less stretched and which allows greater control
of the motorcycle. Basically it translated the custom
spirit into a language that everyone can understand,
appealing to bikers from all different backgrounds
and experiences. Particularly appealing to female
riders who appreciate the low weight and agility,
the Nevada Classic is suited for any use, including
long range touring. Equipped with side bags, top box
and a windshield, the Nevada Classic transforms into
a comfortable and practical Grand Tourism bike, economical
with fuel and maintenance thanks to the final cardan
joint drive which characterises the two cylinders
from Mandello del Lario.
The new Nevada is available in the classic “Aquila
Nera” livery, based on the contrast between
the historic gold coloured Moto Guzzi logo and the
superstructures painted “coal black” and
in a new colour designed to emphasise the insertion
of the new single throttle two cylinder.
NEVADA ANNIVERSARIO:
Created in 2010 to celebrate the twentieth anniversary
of the mid-sized custom from Mandello, the Anniversario
joins range alongside the timeless Classic to offer
the choice of a bike with more eye-catching, contemporary
looks. Inspired by a concept of more sporty and dynamic
style, the "sporty custom" from Mandello
is more muscular and rebellious compared to the Classic,
particularly from the side view, where the new two-up
saddle seems to perch on top of the fat rear tyre
with the wheel-hugging two-tone rear mudguard sprouting
out from behind.
Completing the revised looks of the tail is a set
of brand new chrome plated grab handles, yet another
styling touch distinguishing the bike from the original
Classic.
The design of the centre section of the Anniversario
showcases the beating heart of the bike, the brand
new single throttle, two cylinder small block. To
further show off its revamped layout, the side fairings
have been redesigned to complement the forms of the
14 litre tank. The tank itself seems suspended over
the V of the two opposed cylinders in a visual effect
created by the two-tone colour scheme, with black
dominating the lower part of the bike, and white the
predominant colour of the upper area consisting of
the top of the tank and the mudguards, with a delicate
orange pinstripe separating the two areas. The result
is a bike with distinctly sporty looks that is further
emphasised by the low bar handlebars which, in keeping
with the spirit of the bike, are lower and narrower
than the bars on the Classic and which determine a
more forward riding position.
The distinctly sporty spirit of the Nevada Anniversario
benefits from the new single throttle two cylinder
both from a performance point of view and from the
sensation which it is able to provide through pulsations
and sounds which emphasise the greater compression
ratio and the different intake compared to the previous
generation engine.
