This manual provides the main information to carry out regular maintenance operations on your vehicle.
This manual is intended to Moto Guzzi Dealers and their qualified mechanics; several concepts have
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 InternationalSubsidiaries. 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 CUSTOMERDEPARTMENT, which will be prepared to provide any information on the subject and any further
communications on updates and technical changes related to the vehicle.

enclosed area, make sure to use a fume extraction system.
CAUTION
EXHAUST EMISSIONS CONTAIN CARBON MONOXIDE, A POISONOUS GAS WHICH CAN CAUSE
LOSS OF CONSCIOUSNESS AND EVEN DEATH.
Fuel
CAUTION
THE FUEL USED TO POWER INTERNAL COMBUSTION ENGINES IS HIGHLY FLAMMABLE AND
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 OR NEAR FUEL VAPOUR.
AVOID ANY CONTACT WITH NAKED FLAME, SPARKS OR OTHER HEAT SOURCES WHICH MAY
CAUSE IGNITION OR EXPLOSION.
DO NOT ALLOW FUEL TO DISPERSE INTO THE ENVIRONMENT.
KEEP OUT OF THE REACH OF CHILDREN
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 LATEX GLOVES WHEN SERVICING THE VEHICLE.
THE ENGINE OR GEARBOX OIL MAY CAUSE SERIOUS INJURIES TO THE SKIN IF HANDLED
FOR PROLONGED PERIODS OF TIME AND ON A REGULAR BASIS.
WASH YOUR HANDS CAREFULLY AFTER HANDLING OIL.
HAND THE OIL OVER TO OR HAVE IT COLLECTED BY THE NEAREST USED OIL RECYCLING
COMPANY OR THE SUPPLIER.
DO NOT DISPOSE OF OIL IN THE ENVIRONMENT
KEEP OUT OF THE REACH OF CHILDREN
Keep mated parts together since they have "adjusted" to each other due to normal wear.
•
Some components must be used together or replaced altogether.
•
Keep away from heat sources.
REASSEMBLING COMPONENTS
CAUTION
BEARINGS MUST ROTATE FREELY, WITHOUT JAMMING AND/OR NOISE, OTHERWISE, 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 applying the tightening torque.
•
Always replace self-locking nuts, washers, sealing rings, circlips, O-rings (OR), split 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 vehicle 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 wiring harness:
Press the relative safety clips, if applicable.
•
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
DO NOT DISCONNECT CONNECTORS BY PULLING THE CABLES.
NOTE
THE TWO CONNECTORS CAN ONLY BE CONNECTED IN ONE DIRECTION: CONNECT THEM
THE RIGHT WAY ROUND.
TIGHTENING TORQUES
CAUTION
REMEMBER THAT THE TIGHTENING TORQUES FOR ALL FASTENING ELEMENTS ON WHEELS,
BRAKES, WHEEL AXLES AND ANY OTHER SUSPENSION COMPONENTS PLAY A KEY ROLE
IN ENSURING VEHICLE SAFETY AND MUST COMPLY WITH SPECIFIED VALUES. CHECK THE
TIGHTENING TORQUES OF FASTENING ELEMENTS ON A REGULAR BASIS AND ALWAYS USE
A TORQUE WRENCH TO REASSEMBLE THESE COMPONENTS. FAILURE TO COMPLY WITH
THESE RECOMMENDATIONS MAY CAUSE ONE OF THESE COMPONENTS TO LOOSEN OR
EVEN DETACH, CAUSING A WHEEL TO LOCK OR COMPROMISING VEHICLE HANDLING. THIS
MAY 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 DISCS
GET ADAPTED.
IT IS IMPORTANT TO STRAIN ENGINE COMPONENTS DURING RUN-IN, HOWEVER, MAKE SURE
NOT TO OVERDO THIS.
CAUTION
THE FULL PERFORMANCE OF THE VEHICLE IS ONLY AVAILABLE AFTER THE SERVICE AT
THE END OF THE RUN-IN PERIOD.
Follow the guidelines detailed below:
•
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.
