Dear rider
First
of all we wish to thank you for choosing this motorcycle.
By following the instructions outlined in this manual you will ensure
that your bike has a long and troublefree life.
Before riding, please read this manual thoroughly
in order to get to
know your motorcycle's features and
how to use it safely.
All major inspections and overhauls should be carried out by our
dealers who have the facilities necessary
to guarantee an efficient
and competent service.
Repairs
or adjustments by anyotherthan a Moto Guzzidealerduring
the warranty period could invalidate the warranty.

RIDING TECHNIQUE
Due to its exceptional features, this motor-
cycle can be considered as in the same
class as racing machines, and should be
ridden as such.
For this very reason it is enjoyed by many
enthusiasts, but as with racing motor-
cycles, the riding technique must be ap-
propriate.
Above all else, given that the carburetors
are fitted with accelerator pumps, if the
throttle isn't used correctly in relation to
the engine speed, any excess fuel ex-
pelled by the carburetors will end up in the
carburetor air intake filter.
When travelling at low speeds, or more
correctly at low engine speeds, the throttle
must be used ca refu ll y, since the excess
fuel might not be fully burned by the en-
gine; at high engine speeds, even with
abrupt accelerations , the fuel is complete-
ly burned , producing that exhilarating and
distinguishing " pick-up ".

AERODYNAMIC DEVELOPMENT
Reproducing ideal driving conditions
in a free flow
wind tunnel,
the aerodynamics has been optimised
by designing an integral cockpit fairing,
to create an air flow that envelopes
the rider , enclosing him in an isolated
air pocket, and with special profiling,
producing negative lift and hence
stable road-holding, with an increase
in stability proportional to the
increase in speed.
Low drag coeffecient and low total
weight make for higher speeds and
lower fuel consumption than obtained
on any other motorcycle of similar
engine capacity.

18 Cleaning the windshield
Mos t soaps, detergents, waxes and po li shes used
for plastics or glass , can be used to clean the wind-
shield. However, the following precautioos should
be taken :
• never ... h or clean the windshield when the
.1, Wmper.tur. i. very high , or underatrongaun-
light;
• under no ci rcumstan ces sho uld solvents, caus-
tlc solu ti ons, or similar produc ts be used;
• do not use liquids contai ning abrasive materials,
CJ( pumice, glass paper, scrapers, etc .;
"
"
• apply polishes only after having thoroughly
washed off all dust and dirt:
• Ught scratches can be smoothed over with a soft
po li sh;
• fresh paint and seali
ng compounds can easily
be removed belore they harden, by rubbing lightly
with gasoline, isopropyl alcohol
or butyl celiosolYe
(do not use methylated spirits);
• always use soft cloths, sponges, chamois lea-
ther orcotton wool rubbing gentty. Do not use paper
towels or synthetic fiber cloths as these lend to
scratch the windshield.
Deepscratches or abrasions cannot be removed by
vigorous rubbing or by the use of solvents.
