Ifbattery fluid is spilled into your eyes, flush with abundant water for fifteen minutes and contact an eyespecialist immediately.If battery fluid is swallowed accidentally, drink abundant water or milk. Immediately seek medicalattention and keep drinking milk of magnesia or vegetable oil in the meantime.The battery gives off explosive gases. Keep the battery well away from any sources of ignition, suchas flames, sparks, or any heat sources.Make sure the area is well ventilated when servicing or refilling the battery.


Battery fluid is corrosive.Avoid spillage. Take special care not to spill battery fluid on plastic parts.Ensure that the electrolyte fluid you are using is the suitable type for your battery.

GENERAL PRECAUTIONS AND INFORMATIONFollow these instructions closely when repairing, disassembling or reassembling the motorcycle or its components.

DANGERDo not use open flames when working on the vehicle. Before proceeding to maintain or inspect themotorcycle, stop the engine and remove the ignition switch key. Ensure that the engine and exhaustsystem have cooled down. Wherever possible, place the motorcycle on firm and level ground and lift itusing suitable equipment. Pay special attention to hot engine parts and the exhaust system: burnshazard.Do not hold mechanical parts or engine components in the mouth, as some of them are made of toxicmaterials.Unless otherwise specified, re-assembly takes place in the reverse order to disassembly. Where aprocedure is cross-referred to relevant sections in the manual, proceed sensibly to avoid disturbingany parts unless strictly necessary. Never use abrasive pastes to polish opaque paintwork.Never use fuel instead of solvent to clean the motorcycle.Do not use alcohol, petrol or solvents to clean the rubber and plastic parts and the saddle: use onlywater and mild soap.Always disconnect the battery negative () lead before soldering any electrical components.When two or more persons service the same motorcycle together, special care must be taken to avoidpersonal injury.For more details see (HAZARDOUS COMPONENTS)

BEFORE DISASSEMBLING ANY COMPONENTS• Clean off all dirt, mud, and dust and clear any foreign objects from the vehicle before disassembling any

components.• Use the model-specific special tools where specified.

DISASSEMBLING THE COMPONENTS- Never use pliers or similar tools to slacken and/or tighten nuts and bolts. Always use a suitable spanner.- Mark all connections (hoses, wiring, etc.) with their positions before disconnecting them. Identify each connection

using a distinctive symbol or convention.- Mark each part clearly to avoid confusion when refitting.- Thoroughly clean and wash any components you have removed using a detergent with low flash point.- Mated parts should always be kept together. These parts will have seated themselves against one another in service

as a result of normal wear and tear.- Certain components are matched-pair parts and should always be used together or replaced as a set.- Keep the motorcycle and its components well away from heat sources.

REASSEMBLING THE COMPONENTS

DANGERNever reuse circlips or snap rings. These parts must always be renewed once they have beendisassembled.When fitting a new circlip or snap ring, open the ends just sufficiently to allow fitment to the shaft.Make a rule to check that a newly-fitted circlip or snap ring has located fully into its groove.Never use compressed air to clean bearings.

IMPORTANT: All bearings must run freely with no hardness or noise. Replace any bearings that do not meet theserequirements.

- Use ORIGINAL Moto Guzzi SPARE PARTS only.- Use the specified lubricants and consumables.- Where possible, lubricate a part before assembly.- When tightening nuts and bolts, start with the largest or innermost nut/bolt and observe a cross pattern. Tighten

evenly in subsequent steps until achieving the specified torque.- Replace any self-locking nuts, gaskets, seals, circlips or snap rings, O-rings, split pins, bolts and screws which have

a damaged thread.- Lubricate bearings abundantly before assembly.- Make a rule to check that all components you have fitted are correctly in place.- After repairing the motorcycle and after each service inspection, perform the preliminary checks, and then operate

the motorcycle in a private estate area or in a safe area away from traffic.- Clean all mating surfaces, oil seal edges and gaskets before assembly. Apply a light coat of lithium grease along the

edges of oil seals. Fit oil seals and bearings with the brand or serial number facing outwards (in view).

ELECTRICAL CONNECTORSDisconnect electrical connectors as follows: failure to follow the instructions can seriously damage the connectors andthe wiring:Press down on the locking tab, where fitted.

WARNINGNever separate two connectors by pulling on the wiring.

• Grasp both connectors and pull them in opposite directions until they become separated.• Remove any dirt, rust, moisture, etc. from inside the connector with compressed air.• Ensure that the wires are securely crimped to the terminals inside each connector.

IMPORTANT: A connector will only locate properly into the matching connector when it is inserted in the correctmounting position.

• Reconnect the two connectors and ensure that they are fully engaged (if fitted with a locking tab, it should clickaudibly into place).

TIGHTENING TORQUES

DANGERDo not forget that the tightening torques of all fastenings on wheels, brakes, wheel spindles and othersuspension components are essential to ensuring safe operation of the motorcycle and must be set tothe indicated values.Regularly check the tightening torques on all fastenings, and always use a torque wrench when fittingthem. Failure to observe these instructions can result in parts loosening or coming away, thusjamming a wheel or creating other problems which could affect the handling of the motorcycle,potentially resulting in serious injury or death.

1.3. HAZARDOUS SUBSTANCES1.3.1. WARNINGS

FUEL

DANGERThe fuel used for internal combustion engines is extremely inflammable and in particular conditions itcan become explosive.It is important to carry out the refueling and the maintenance operations in a well-ventilated area, withthe engine off.Do not smoke when refueling or in the proximity of sources of fuel vapors. Avoid contact with bareflames, sources of sparks or any other source which may ignite the fuel or lead to explosion.Take care not to spill fuel out of the filler, or it may ignite when in contact with hot engine parts.In the event of accidental fuel spillage, make sure the affected area is fully dry before starting theengine. Fuel expands from heat and when left under direct sunlight.Never fill the tank to the brim. Tighten the filler cap securely after each refueling.Avoid any contact of the fuel with the skin and the inhalation of vapors; do not swallow fuel or pour itfrom a receptacle into another by means of a tube.DO NOT DISPOSE OF FUEL IN THE ENVIRONMENT.KEEP AWAY FROM CHILDREN.

Use only premium-grade unleaded fuel with a minimum octane rating of 95 (N.O.R.M.) and 85 (N.O.M.M.).

LUBRICANTS

DANGERCorrect lubrication is essential to the safety of the motorcycle.Failure to maintain the lubricant level or the use of incorrect, old or dirty lubricant can cause theengine or transmission to seize, resulting in accidents, serious injury or death.Prolonged or repeated contact with engine oil may cause severe skin damage.Wash your hands thoroughly after handling engine oil.Do not dispose of oil in the environment.Dispose of engine oil through the nearest waste oil reclamation firm or through the supplier.

WARNINGWhen filling the vehicle with lubricant, make sure not to spill it. Immediately clean up spilled oil, as itcan damage the motorcycle's paint.Oil on the tires can make them very slippery and dangerous to use.In case of oil leaks, do not use the vehicle. Identify the cause of the leak and repair it.

ENGINE OIL

DANGERProlonged or repeated contact with engine oil may cause severe skin damage.Wash your hands thoroughly after handling engine oil.Do not dispose of oil in the environment.Dispose of engine oil through the nearest waste oil reclamation firm or through the supplier.Wear latex gloves during servicing.

FRONT FORK FLUID

DANGERModifying the suspension settings or the viscosity of the front fork oil will affect its response.Standard oil viscosity: SAE 20 W. Choose the oil viscosity to determine the type of response required(SAE 5W for a softer suspension, 20W for a stiffer suspension).The two grades can also be mixed in varying solutions to obtain the desired response.

BRAKE FLUID

IMPORTANT This motorcycle is fitted with two (front and rear) disk brakes with independent hydraulic circuits. Theinformation provided below applies to both braking systems.

DANGERDo not use the vehicle if the brakes are worn or malfunctioning! The brakes are the most importantsafety component on the vehicle, and using the vehicle with the brakes in less than perfect conditionis very likely to result in an accident, with the risk of serious personal injury or death.The brakes are significantly less effective on a wet road surface.

DANGERIf the road surface is wet with rain, maintain a double braking distance, inasmuch as both the brakesthemselves and the grip of the tires are significantly less effective in such conditions.Water on the brakes, whether due to a recent wash or picked up from the wet road surface, puddles ordrains, can result in significantly reduced brake effectiveness.Failure to observe these instructions can result in serious accidents, with the risk of serious personalinjury or death.The brakes are essential to your safety. Do not use the vehicle if the brakes are not in perfect workingorder.Always check the brakes before riding the motorcycle.Brake fluid is an irritant. Avoid contact with eyes or skin.In the event of accidental contact, wash affected body parts thoroughly. In the event of accidentalcontact with eyes, contact an eye specialist or seek medical advice.DO NOT DISPOSE OF THE FLUID IN THE ENVIRONMENT.KEEP AWAY FROM CHILDREN.When handling brake fluid, take care not to spill it onto plastic or paint-finished parts or they willdamage.

DANGERDo not use any brake fluids other than the specified type. Never mix different types of fluids to top uplevel, as this will damage the braking system.Do not use brake fluid from containers which have been kept open or in storage for long periods.Sudden resistance or clearance problems on the brake levers may be due to troubles in the hydrauliccircuits.Ensure that the brake discs and friction material have not become contaminated with oil or grease.This is particularly important after servicing or inspections.Make sure the brake lines are not twisted or worn.Avoid accidental ingress of water or dust into the circuit.Wear latex gloves when servicing the hydraulic circuit.

DISK BRAKES

DANGERThe brakes are the vehicles most important safety component.To ensure your personal safety, they must be in perfect working order and should be checked beforeevery ride.Oil or other liquids on the disks will contaminate the brake pads.Dirty pads must be replaced. A dirty or oily disk should be cleaned with a high quality degreaser.If the vehicle is often used on wet road surfaces or on dusty or rough tracks, or in case of use incompetition, reduce the service intervals by half.Check the wear of the brake pads.When the pads are worn, the fluid level in the tank lowers to compensate for the wear.The front brake fluid reservoir is on the RH side of the handlebar, next to the front brake lever.The rear brake fluid reservoir is under the RH side fairing.Do not use the vehicle if the brake system is leaking in any position.

COOLANT

DANGERCoolant is toxic when ingested and is an irritant, contact with eyes or skin may cause irritation.On the event of contact with the skin or the eyes, rinse repeatedly with abundant water and seekmedical advice. If swallowed, provoke vomiting, rinse the mouth and throat with abundant water andimmediately seek medical attention.DO NOT DISPOSE OF THE FLUID IN THE ENVIRONMENT.KEEP AWAY FROM CHILDREN.

DANGERTake care not to spill coolant onto hot engine parts. It may ignite and produce invisible flames. Wearlatex gloves when working on the system.Do not ride when coolant is below the minimum level.

Coolant mixture is a 50% solution of water and anti-freeze. This is the ideal solution for most operating temperatures andprovides good corrosion protection.This solution is also suited to the warm season, as it is less prone to evaporative loss and will reduce the need for top-ups.In addition, less water evaporation means fewer minerals salts depositing in the radiator, which helps preserve theefficiency of the cooling system.When the outside temperature drops below freezing, check the coolant circuit frequently and add more anti-freeze (up to60% maximum) to the solution.Use distilled water in the coolant mixture. Tap water will damage the engine.Refer to the chart given below and add water with the quantity of anti-freeze to obtain a solution with the desired freezingpoint:

Freezing point °F (°C) Coolant % of volume-4 (-20) 35-22 (-30) 45-40 (-40) 55

IMPORTANT The different brands of anti-freeze available on the market have varying specifications. Always readproduct label to determine the degree of protection afforded.

WARNINGUse only nitrite-free anti-freeze and corrosion inhibitors with a freezing point of -35°C as a minimum.

TIRES

WARNINGAn overinflated tire results in a hard, uncomfortable and less secure ride.Overinflation also affects grip, especially on curves and in the wet.An underinflated tire (insufficient pressure) can slip on the wheel rim, resulting in loss of control.Underinflation also affects grip and handling, as well as braking efficiency.Tire replacement and repair, and wheel servicing and balancing are delicate operations. They shouldbe carried out using adequate tools and are best left to experienced mechanics.New tires may be covered by a thin protective cover which has reduced grip. Ride carefully for thefirst few kilometers (miles).Never use any kind of rubber treatment product on the tires.In particular, take care not to allow the tire to come into contact with liquid fuel, which rapidlydeteriorates the tire rubber.A tire which has come into contact with oil or fuel cannot be cleaned and must be replaced.

DANGERCertain OEM tires are equipped with wear indicators.There are various types of wear indicators.Contact your Dealership for tire checking information.Check tire wear visually and have the tires replaced when they are worn.If a tire deflates during a ride, do not attempt to continue the trip.Avoid sudden braking or steering maneuvers, and do not decelerate rapidly.Slowly decelerate and move to the edge of the road braking with the engine until you come to astandstill.Failure to observe these instructions can result in serious accidents, with the risk of serious personalinjury or death.Never use tube tires on tubeless tire rims, or vice versa.

1.4. RUNNING-IN1.4.1. RUNNING-IN

Proper engine running-in is essential to preserving engine life and performance over time.Twisty roads and gradients are ideal to break in engine, suspension and brakes effectively.Varying speed frequently is also recommended.This will vary the amount of stress placed on vehicle components continuously, allowing engine parts to cool down whenless stressed.While it is important to put a certain amount of stress to engine components during the running-in period, it is equallyimportant to spare the engine at this stage in vehicle's life.

WARNINGTop acceleration performance is only obtained after covering the first 1243 mi (2000 km).

Observe the following instructions:• Avoid harsh accelerations and do not flip the throttle open abruptly when the engine is running at low speed, both

during and after the running-in period.• Apply the brakes gently and avoid hard, prolonged braking for the first 62 mi (100 km). This will allow the brake pad

lining to wear in properly rubbing on the brake discs.• Never exceed 5000 rpm during the first 932 mi (1500 km) (see chart).

WARNINGAfter the first 932 mi (1500 km), perform the checks listed in the post running-in column of thePERIODIC MAINTENANCE CHART. Failure to perform these checks may lead to personal injury toyourself or third persons, or vehicle damage.

• Between the first 932 mi (1500 km) and 1243 mi (2000 km), a somewhat brisker riding style is acceptable. Vary yourspeed and use peak acceleration for just a few instants, to allow the different components to become properlyseated against one another. However, avoid exceeding 6000 rpm (see chart).

• After 1243 mi (2000 km), the engine will be ready for a more demanding use. However, never exceed the maximumengine speed allowed (7600 rpm).
