2009 Moto Guzzi Griso 8V
   
His power was increased both by the
fact itself and in public opinion”. This quote
from “I promessi sposi” by Alessandro
Manzoni, refers to Griso, the head of a group known
as the “Bravi” “to whom the most
dangerous jobs were entrusted”. This refers
to the character of the new Griso 8V that is the smartest
and most high spirited Moto Guzzi ever made and that
encompasses an absolute new sense of “Sporting
spirit” stemming from the power and technology
of the innovative “Quattrovalvole” engine.
Although designed along traditional lines, the new
engine features 563 brand new components and is a
celebration of the logic behind the 90° V concept.
It features a single overhead camshaft per head that
operates the four valves on each cylinder with noiseless
timing chains. This is quite an evolution of the 1200
cc engine that, with its 75% of its components renewed,
now puts out 110 CV at 7,500 rpm with maximum torque
of 11 kgm at 6,400 rpm.
The power delivery is silky smooth and on the open
road the bike’s true sports character shines
along with the countless technical innovations and
the new sense of style. Although the exclusive exhaust
system with twin coiled pipes has been seen before,
it now truly reflects the greater power of these machines.
From the looks point of view, the Griso 8V has undergone
customising that includes particular stylistic details
like the new saddle and streamlined bodywork as well
as equipment levels of the highest possible level.
Even the most discerning of palates will appreciate
the front end with its Brembo P4/34 radial caliper
brakes that act on wave floating discs measuring Ø
320mm.
They will also delight in the Showa upside-down forks
that have had 43 layers of carbon nitride treatment.
Sitting astride the bike, the rider can immediately
appreciate the sports riding position that the new
setup between handlebars, saddle and footpegs provides.
These are all new components and were specially designed
to make the rider feel completely in control. The
two-seater saddle creates a superb rear view and there
seems to be a tail like on a single seater. In fact
there is more than enough room for a passenger to
sit in great comfort. Powerful, elegant and exclusive,
the Griso 8V will soon become an icon among those
who truly appreciate elite motorcycles. The Griso
is offered in three colour schemes: Jet Black, Moon
White and Corsa Red.
