Battery electrolyte and hydrogen gas
CAUTION
THE BATTERY ELECTROLYTE IS TOXIC, CORROSIVE AND, AS IT CONTAINS SULPHURIC
ACID, MAY CAUSE BURNING IF IT COMES INTO CONTACT WITH THE SKIN. WHEN HANDLING
BATTERY ELECTROLYTE, WEAR TIGHT-FITTING GLOVES AND PROTECTIVE APPAREL. IN
THE EVENT OF SKIN CONTACT WITH THE ELECTROLYTIC FLUID, RINSE WELL WITH PLENTY
OF CLEAN WATER. IT IS PARTICULARLY IMPORTANT TO PROTECT YOUR EYES BECAUSE
EVEN TINY AMOUNTS OF BATTERY ACID MAY CAUSE BLINDNESS. IN THE EVENT OF CON-
TACT WITH THE EYES, RINSE WITH PLENTY OF WATER FOR FIFTEEN MINUTES AND CON-
SULT AN EYE SPECIALIST IMMEDIATELY. IF THE FLUID IS ACCIDENTALLY SWALLOWED,
DRINK LARGE QUANTITIES OF WATER OR MILK, FOLLOWED BY MILK OF MAGNESIA OR
VEGETABLE OIL AND SEEK MEDICAL ADVICE IMMEDIATELY. THE BATTERY RELEASES EX-
PLOSIVE GASES; KEEP IT AWAY FROM FLAMES, SPARKS, CIGARETTES OR ANY OTHER
HEAT SOURCES. ENSURE ADEQUATE VENTILATION WHEN SERVICING OR RECHARGING

Maintenance rules
GENERAL PRECAUTIONS AND INFORMATION
When repairing, dismantling and reassembling the vehicle, follow the recommendations given below
carefully.
BEFORE DISASSEMBLING COMPONENTS
•Beforedismantling components, remove dirt, mud, dust and foreignbodies from the vehicle.
Use the special tools designed for this bike, as required.
COMPONENTS REMOVAL
•Donot loosen and/ortighten screws andnuts using pliersor 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.
Characteristics STELVIO 1200 NTX
CHAR - 8
Revente Interdite - Revendita Vietata - Resaling Forbiden - Wiederverkauf Verboten

•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 ap-
plying 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 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 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
REMEMBERTHATTHETIGHTENINGTORQUES FORALLFASTENING ELEMENTSONWHEELS,
BRAKES, WHEEL AXLES AND ANY OTHER SUSPENSION COMPONENTS PLAY A KEY ROLE
STELVIO 1200 NTX Characteristics

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.
ITISIMPORTANTTOSTRAIN ENGINECOMPONENTS DURINGRUN-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 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.

Overhaul data
Assembly clearances
Cylinder - piston assy.
Measurement of the cylinder diameter must be done at three heights, turning the dial gauge 90°.
Check that cylinders and pistons are of the same selection types (D, E, F).
Check clearance between cylinders and pistons on the selected diameter; if it exceeds the value speci-
fied, it is necessary to replace cylinders and pistons.
The pistons of an engine must be balanced; a weight difference of up to 1.5 g (0.0033 lb) is allowed.
