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.
