2008 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.
DISTINGUISHING MARKS - BEAUTIFUL.
The sinuous tubes of the frame wrap around the tank - the sides are like forearms pointing straight ahead – the exhaust manifolds coil round the engine. Everything about the Griso is a little strange, a little unsettling maybe – not normal…It is however very like the bike we all imagine or even dream of having The Griso is a masterpiece on wheels. A dynamic work of art that demonstrates sheer Italian creativity crowned by the Moto Guzzi eagle that puts it way beyond any classification. The feelings aroused by its aggressive raw lines get stronger when you climb aboard. The riding position offered by the saddle and wide handlebars mean maximum control and fast changes of direction whether in heavy traffic or on the open road. Thanks to the long wheelbase, the bike is very stable but surprisingly agile due to its wonderful frame. The steel frame is both rigid and reactive. The adjustable suspension adapts to all surfaces and changes in loads.
Constant full-bodied power is supplied by a 90 degree V twin of the latest generation that has been completely updated and meets Euro 3 emission standards. The torque produced by the engine is delivered to the wheels via a silky smooth reactive shaft drive transmission system patented by Moto Guzzi. The sound made by this machine has no comparison. It is a deep throbbing note that comes first out of twin manifolds then on to stainless steel silencers. No matter how many miles flick by on the futuristic mileometer display on the onboard computer, your Griso will never go unnoticed. Its elegant Guzzi Black, Racing Red or new satinised Orange colour schemes make it both elegant and hard to miss.
