- This manual is intended to aprilia 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 vehicles. 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, aprilia 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 aprilia 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 aprilia 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.

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.

Coolant

The coolant contains ethylene glycol which, under certain conditions, can become flammable.

When it burns, ethylene glycol produces an invisible flame which however can cause burns.

CAUTION

TAKE CARE NOT TO SPILL COOLANT ONTO HOT ENGINE OR EXHAUST SYSTEM COMPO-

NENTS; THE FLUID MAY IGNITE AND BURN WITH AN INVISIBLE FLAME. WHEN CARRYING

OUT MAINTENANCE, IT IS ADVISABLE TO WEAR LATEX GLOVES. EVEN THOUGH IT IS TOXIC,

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 foreign bodies from the vehicle.

Use the special tools designed for this bike, as required.

COMPONENTS REMOVAL

•Donotloosenand/ortightenscrewsandnutsusingpliersoranyothertoolsthanthespecific

wrench.

•Mark positions on all connection joints (pipes, cables etc.) before separating them, and

identify them with 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 MXV 450

CHAR - 8

•Some components must be used together or replaced completely.

•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 aprilia 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.

•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 bearings with the brand or

lot number facing outward (visible side).

ELECTRICAL 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 TORQUE

CAUTION

MXV 450 Characteristics

CHAR - 9

DO NOT FORGET THAT TIGHTENING TORQUES FOR ALL FASTENING ELEMENTS ON

WHEELS, BRAKES, WHEEL PINS AND ANY OTHER SUSPENSION COMPONENTS PLAY A KEY

ROLE IN ENSURING THE VEHICLE'S SAFETY AND MUST COMPLY WITH SPECIFIED VALUES.

CHECK THE TIGHTENING TORQUES OF FASTENING PARTS ON A REGULAR BASIS AND AL-

WAYS USE A TORQUE WRENCH TO REASSEMBLE THESE COMPONENTS. FAILURE TO OB-

SERVE THESE INSTRUCTIONS MAY CAUSE ONE OF THESE COMPONENTS TO BECOME

LOOSE AND EVEN DETACHED, THUS BLOCKING A WHEEL, OR OTHERWISE COMPROMISING

YOUR PROPERLY HANDLING THE VEHICLE. THIS CAN LEAD TO FALLS, WITH THE RISK OF

SERIOUS PERSONAL INJURIES OR EVEN DEATH.

Running-in

In order to ensure enhanced reliability and performance along time, special attention should be given

to the first riding day or during the first 2 hours the vehicle is used.

During this time, avoid setting off at too high a speed or sudden accelerations.

These procedures have to be carried out each time:

•pistons are replaced

•piston rings are replaced

•cylinder liners are replaced

•crankshaft, main bearings and connecting rod bushings are replaced.

NOTE

EVEN AFTER THE RUNNING-IN PERIOD, AVOID RUNNING THE ENGINE AT TOP SPEED, WHEN
