Rules Safety rules Carbon monoxide If you need to keep the engine running while working on the vehicle, please ensure that you do so in an open or very well ventilated area. Never let the engine run in an enclosed area. If you do work in an 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 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. 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. Before handling these components, make sure that you are wearing 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 POUR COOLANT ONTO HOT ENGINE OR EXHAUST SYSTEM COMPO- NENTS; THE FLUID MAY CATCH FIRE AND BURN WITH INVISIBLE FLAMES. WHEN CARRYING OUT MAINTENANCE OPERATIONS, IT IS ADVISABLE TO WEAR LATEX GLOVES. EVEN THOUGH IT IS TOXIC, COOLANT HAS A SWEET FLAVOUR WHICH MAKES IT VERY ATTRAC- TIVE TO ANIMALS. NEVER LEAVE THE COOLANT IN OPEN CONTAINERS IN AREAS ACCES- SIBLE TO ANIMALS AS THEY MAY DRINK IT. SX - RX 50 Characteristics CHAR - 7

KEEP OUT OF THE REACH OF CHILDREN DO NOT REMOVE THE RADIATOR CAP WHEN THE ENGINE IS STILL HOT. THE COOLANT IS UNDER PRESSURE AND MAY CAUSE BURNS. 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.

BRAKE AND CLUTCH FLUIDS ARE EXTREMELY HARMFUL FOR YOUR EYES. IN THE EVENT OF ACCIDENTAL CONTACT WITH YOUR EYES, RINSE THEM IMMEDI- ATELY WITH ABUNDANT COLD, CLEAN WATER AND SEEK MEDICAL ADVICE. KEEP OUT OF THE REACH OF CHILDREN Battery electrolyte and hydrogen gas CAUTION THE BATTERY ELECTROLYTE IS TOXIC, CORROSIVE AND AS IT CONTAINS SULPHURIC ACID, IT CAN CAUSE BURNS WHEN IN 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. IF THE FLUID GETS IN CONTACT WITH YOUR EYES, WASH WITH ABUNDANT WATER FOR FIFTEEN MINUTES AND CONSULT 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.

When repairing, dismantling and reassembling the vehicle follow the recommendations reported below carefully. BEFORE REMOVING COMPONENTS • Before dismantling components, remove dirt, mud, dust and foreign bodies from the vehicle. Use the special tools designed for this bike, as required. COMPONENTS REMOVAL • Do not loosen and/or tighten screws 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. • 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 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 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 seals and bearings with the brand or batch number facing outward (visible side). ELECTRIC CONNECTORS Electric connectors must be disconnected as described below; failure to comply with this procedure causes irreparable damages to both the connector and the cable harness: Press the relevant safety hooks, if any. SX - RX 50 Characteristics CHAR - 9

• 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. CHECK THE TIGHTENING TORQUE 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 running in period. In this way, you allow for the work of components to be "loaded" and then "unloaded", thus cooling engine parts. 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) brake carefully to avoid rough and long braking. That is to permit the adequate adjustment of the pad friction material to the brake discs. Vehicle identification CAUTION CHANGING THE IDENTIFICATION CODE IS A CRIME THAT MAY BE PUNISHED WITH SERIOUS CRIMINAL CHARGES.
