been deliberately omitted as they are considered unnecessary. As it is not possible to include complete
mechanical notions in this manual, users should have basic mechanical knowledge or minimum
knowledge about the procedures involved when repairing scooters. Without this knowledge, repairing or
checking the vehicle may be inefficient or even dangerous. As the vehicle repair and check procedures
are not described in detail, be extremely cautious so as not to damage components or injure individuals.
In order to optimise customer satisfaction when using our vehicles, Moto Guzzi s.p.a. commits itself to
continually improve its products and the relative documentation. The main technical modifications and
changes in repair procedures are communicated to all Moto Guzzi Sales Outlets and its International
Subsidiaries. These changes will be introduced in the subsequent editions of the manual. In case of
need or further queries on repair and check procedures, consult Moto Guzzi CUSTOMER
DEPARTMENT, which will be prepared to provide any information on the subject and any further
communications on updates and technical changes related to the vehicle.

MAY BE EXPLOSIVE UNDER CERTAIN CONDITIONS. IT IS THEREFORE RECOMMENDED TO
CARRY OUT REFUELLING AND MAINTENANCE PROCEDURES IN A VENTILATED AREA WITH
THE ENGINE SWITCHED OFF. DO NOT SMOKE DURING REFUELLING AND NEAR FUEL VA-
POURS, AVOIDING ANY CONTACT WITH NAKED FLAMES, SPARKS OR OTHER SOURCES
WHICH MAY CAUSE THEM TO IGNITE OR EXPLODE.
DO NOT DISPERSE FUEL IN THE ENVIRONMENT.

Hot components
The engine and the exhaust system components become very hot and remain hot for some time after
the engine has been switched off. When handling these components, wear insulating gloves or wait
until the engine and the exhaust system have cooled down.
Used engine oil and transmission oil
CAUTION
IT IS ADVISABLE TO WEAR PROTECTIVE IMPERMEABLE GLOVES WHEN SERVICING THE VE-
HICLE.
THE ENGINE OR GEARBOX OIL MAY CAUSE SERIOUS INJURIES TO THE SKIN IF HANDLED

Maintenance rules
GENERAL PRECAUTIONS AND INFORMATION
When repairing, dismantling and reassembling the vehicle follow the recommendations reported below
carefully.
BEFORE REMOVING COMPONENTS
•Beforedismantling components, remove dirt, mud,dust andforeign bodiesfrom thevehicle.
Use the special tools designed for this bike, as required.
COMPONENTS REMOVAL
•Donot loosenand/or tightenscrews and nuts using pliers or any other tools than the specific
wrench.
•Mark the positions on all connection joints (pipes, cables, etc.) before separating them, and
identify them with different distinctive symbols.
•Each component needs to be clearly marked to enable identification during reassembly.
•Clean and wash the dismantled components carefully using a low-flammability detergent.
•Keep mated parts together since they have "adjusted" to each other due to normal wear.
Characteristics GRISO 8V - 1200
CHAR - 8

•Some components must be used together or replaced altogether.
•Keep away from heat sources.
REASSEMBLY OF COMPONENTS
CAUTION
BEARINGS MUST BE ABLE TO ROTATE FREELY, WITHOUT JAMMING AND/OR NOISE: OTH-
ERWISE, THEY NEED TO BE REPLACED.
•Only use ORIGINAL Moto Guzzi SPARE PARTS.
•Comply with lubricant and consumables use guidelines.
•Lubricate parts (whenever possible) before reassembling them.
•When tightening nuts and screws, start from the ones with the largest section or from the
internal ones, moving diagonally. Tighten nuts and screws in successive steps before ap-
plying the tightening torque.
•Always replace self-locking nuts, washers, sealing rings, circlips, O-rings (OR), cotter pins
and screws with new ones if their tread is damaged.
•When assembling the bearings, make sure to lubricate them well.
•Check that each component is assembled correctly.
•After a repair or routine maintenance procedure, carry out pre-ride checks and test the ve-
hicle on private grounds or in an area with low traffic density.
•Clean all coupling surfaces, oil guard rims and gaskets before refitting them. Smear a light
layer of lithium-based grease on the oil guard rims. Reassemble oil guards and bearings
with the brand or lot number facing outward (visible side).
ELECTRIC CONNECTORS
Electric connectors must be disconnected as described below; failure to comply with this procedure
causes irreparable damage to both the connector and the cable harness:
Press the relevant safety hooks, if any.
•Grip the two connectors and disconnect them by pulling them in opposite directions.
•If any signs of dirt, rust, moisture, etc. are noted, clean the inside of the connector carefully
with a jet of compressed air.
•Ensure that the cables are correctly fastened to the internal connector terminals.
•Then connect the two connectors, ensuring that they couple correctly (if fitted with clips, you
will hear them "click" into place).
CAUTION
TO DISCONNECT THE TWO CONNECTORS, DO NOT PULL THE CABLES.
NOTE
THE TWO CONNECTORS CONNECT ONLY FROM ONE SIDE: CONNECT THEM THE RIGHT WAY
ROUND.
TIGHTENING TORQUES
CAUTION
DO NOT FORGET THAT THE TIGHTENING TORQUES OF ALL FASTENING ELEMENTS ON
WHEELS, BRAKES, WHEEL BOLTS AND ANY OTHER SUSPENSION COMPONENTS PLAY A
KEY ROLE IN ENSURING VEHICLE SAFETY AND MUST COMPLY WITH SPECIFIED VALUES.
GRISO 8V - 1200 Characteristics
CHAR - 9

CHECK THE TIGHTENING TORQUES OF FASTENING PARTS ON A REGULAR BASIS AND AL-
WAYS USE A TORQUE WRENCH TO REASSEMBLE THESE COMPONENTS. FAILURE TO COM-
PLY WITH THESE RECOMMENDATIONS MAY CAUSE ONE OF THESE COMPONENTS TO GET
LOOSE AND EVEN DETACHED, THUS BLOCKING A WHEEL, OR OTHERWISE COMPROMISE
VEHICLE HANDLING. THIS CAN LEAD TO FALLS, WITH THE RISK OF SERIOUS INJURY OR
DEATH.
Running-in
Engine run-in is essential to ensure engine long life and correct operation. Twisty roads and gradients
are ideal to run in engine, brakes and suspensions effectively. Vary your riding speed during the run-
in. This ensures that components operate under both "loaded" and "unloaded" conditions, allowing the
engine components to cool.
CAUTION
THE CLUTCH MAY EMIT A SLIGHT BURNING SMELL WHEN FIRST USED. THIS PHENOMENON
SHOULD BE CONSIDERED NORMAL AND WILL DISAPPEAR AS SOON AS THE CLUTCH
PLATES GET ADAPTED.
ITIS IMPORTANT TOSTRAINENGINECOMPONENTS DURING RUN-IN,HOWEVER,MAKESURE
NOT TO OVERDO THIS.
CAUTION
THE FULL PERFORMANCE OF THE VEHICLE IS ONLY AVAILABLE AFTER THE SERVICE AT
THE END OF THE RUNNING IN PERIOD.
Follow these guidelines:
•Do not twist the throttle grip abruptly and completely when the engine is working at a low
revs, either during or after run-in.
•During the first 100 Km (62 miles) use the brakes gently, avoiding sudden or prolonged
braking. That is to permit the adequate adjustment of the pad friction material to the brake
discs.
AFTER THE SPECIFIED MILEAGE, TAKE THE VEHICLE TO AN OFFICIAL Moto Guzzi DEALER
FOR THE CHECKS INDICATED IN THE "AFTER RUN-IN" TABLE IN THE SCHEDULED MAINTE-
NANCE SECTION TO AVOID INJURING YOURSELF, OTHERS AND /OR DAMAGING THE VEHI-
CLE.
