Gradually get to know the vehicle by driving it first in areas with low traffic and/or private areas. The use of medicins, alcohol and drugs or psychotropic substances notably increases the risk of accidents. Be sure that you are in good psychophysical conditions and fit for driving and pay particular attention to physical weariness and drowsiness. Most road accidents are caused by the driver's lack of experience. NEVER lend the vehicle to beginners and, in any case, make sure that the driver has all the requirements for driving. 6 use and maintenance RS 125 Rigorously observe all road signs and national and local road regulations. Avoid abrupt movements that can be dangerous for yourself and other people (for example: rearing up on the back wheel, speeding, etc.), and give due consideration to the road surface, visibility and other driving conditions. Avoid obstacles that could damage the vehicle or make you lose control. Avoid riding in the slipstream created by preceding vehicles in order to increase your speed. Always drive with both hands on the handlebars and both feet on the footrests (or on the rider's footboards), in the correct driving posture. Avoid standing up or stretching your limbs while driving. use and maintenance RS 125 7 OIL COOLER The driver should pay attention and avoid distractions caused by people, things and movements (never smoke, eat, drink, read, etc.) while driving. Use only the vehicle's specific fuels and lubricants indicated in the "LUBRICANT CHART"; check the oil, fuel and coolant levels regularly. If the vehicle has been involved in an accident, make sure that no damage has occurred to the control levers, pipes, wires, braking system and vital parts. If necessary, have the vehicle inspected by an aprilia Official Dealer, who should carefully check the frame, handlebars, suspensions, safety parts and all the devices that you cannot check by yourself. Always remember to report any malfunction to the technicians to help them in their work. Never use the vehicle when the amount of damage it has suffered endangers your safety. 8 use and maintenance RS 125 ONLY ORIGINALS A12 345 Never change the position, inclination or colour of: number plate, direction indicators, lights and horns. Any modification of the vehicle will result in the invalidity of the guarantee. Any modification of the vehicle and/or the removal of original components can compromise vehicle performance levels and safety or even make it illegal. We recommend respecting all regulations and national and local provisions regarding the equipment of the vehicle. In particular, avoid all modifications that increase the vehicle's performance levels or alter its original characteristics. Never race with other vehicles. Avoid off-road driving. #,/4().' Before starting, always wear a correctly fastened crash helmet. Make sure that it is homologated, in good shape, of the right size and that the visor is clean. Wear protective clothing, preferably in light and/or reflecting colours. In this way you will make yourself more visible to the other drivers, thus notably reducing the risk of being knocked down, and you will be more protected in case of fall. This clothing should be very tight-fitting and fastened at the wrists and ankles. Strings, belts and ties should not be hanging loose; prevent these and other objects from interfering with driving by getting entangled with moving parts or driving mechanisms. use and maintenance RS 125 9 Do not keep objects that can be dangerous in case of fall, for example pointed objects like keys, pens, glass vials etc. in your pockets (the same recommendations also apply to passengers). !##%33/2)%3 The owner of the vehicle is responsible for the choice, installation and use of any accessory. Avoid installing accessories that cover horns or lights or that could impair their functions, limit the suspension stroke and the steering angle, hamper the operation of the controls and reduce the distance from the ground and the angle of inclination in turns. Avoid using accessories that hamper access to the controls, since this can prolong reaction times during an emergency. Large fairings and windscreens assembled on the vehicle can produce aerodynamic forces capable of compromising the stability of the vehicle while driving. Make sure that the equipment is well fastened to the vehicle and not dangerous during driving. Do not install electrical devices and do not modify those already existing to avoid electrical overloads, because the vehicle could suddenly stop or there could be a dangerous current shortage in the horn and in the lights. aprilia recommends the use of genuine accessories (aprilia genuine accessories). ,/!$ Be careful and moderate when loading your luggage. Keep any luggage loaded as close as possible to the centre of the vehicle and distribute the load uniformly on both sides, in order to reduce imbalance to the minimum. Furthermore, make sure that the load is firmly secured to the vehicle, especially during long trips. 10 use and maintenance RS 125 KG! Avoid hanging bulky, heavy and/or dangerous objects on the handlebars, mudguards and forks, because the vehicle might respond more slowly in turns and its manoeuvrability could be unavoidably impaired. Do not place bags that are too bulky on the vehicle sides and do not ride with the crash helmet hanging from its string, because it could hit people or obstacles making you lose control of the vehicle. Do not carry any bag if it is not tightly secured to the vehicle. Do not carry bags which protrude too much from the luggage rack or which cover the lights, horn or indicators. Do not carry animals or children on the glove compartment or on the luggage rack. Do not exceed the maximum load allowed for each side-bag. When the vehicle is overloaded, its stability and its manoeuvrability can be compromised. use and maintenance RS 125 11 !22!.'%-%.4 /& 4(% -!). %,%-%.43 +%9 1) 2) 3) 4) 5) 6) 7) 12 Dashboard Left rear-view mirror Ignition switch/steering lock Battery Fuse carrier Fuel tap Saddle lock use and maintenance RS 125 8) 9) 10) 11) 2 stroke oil tank 2 stroke oil tank plug Glove/tool kit compartment Passenger left footrest (snapping, closed/open) 12) Rider left footrest (with spring, always open) 13) Shifting lever 14) Side stand 15) Left fairing 16) Horn +%9 1) Passenger right footrest (snapping, closed/open) 2) Crash helmet cable 3) Rider saddle 4) Air cleaner 5) Rear brake fluid tank 6) 7) 8) 9) 10) 11) Fuel tank plug Expansion tank Coolant expansion tank plug Right rear-view mirror Front brake fluid tank Rear brake pump 12) Rear brake control lever 13) Rider right footrest (with spring, always open) 14) Drive chain use and maintenance RS 125 13 !22!.'%-%.4 /& 4(% ).3425-%.43#/.42/,3 +%9 1) 2) 3) 4) 5) 6) 7) 14 Ignition switch/steering lock ( n - m - s ) Cold start lever (e) Direction indicator switch ( c ) Horn push button ( f ) LAP push button (chronometer) Dimmer switch ( b - a ) High beam signalling push button (a ) use and maintenance RS 125 8) 9) 10) 11) 12) 13) 14) Clutch lever Instruments and indicators Front brake lever Throttle grip Start push button (r) Light switch ( o - p - · ) (not provided for _) Engine stop switch (n - m) ).3425-%.43 !.$ ).$)#!4/23 +%9 1) Multifunction computer programming push buttons 2) Multifunction digital display (coolant temperature - clock - battery voltage - chronometer) 3) Revolution counter 4) Red 2 stroke oil reserve warning light LED ( j ) 5) Green direction indicator warning light ( c ) 6) Green neutral indicator warning light (q ) 7) 8) 9) 10) 11) 12) 12) Blue high beam warning light ( a ) Amber "side stand down" warning light ( \ ) Partial kilometres odometer Odometer trip control Total kilometres odometer Speedometer Speedometer - only km/h scale ^ use and maintenance RS 125 15 ).3425-%.43 !.$ ).$)#!4/23 4!",% Description Direction indicator warning light High beam warning light Revolution counter (rpm) Side stand down warning light 2 stroke oil reserve warning light LED Neutral indicator warning light Partial kilometres odometer Odometer trip control Total kilometres odometer Speedometer (\) (c) (a) Function Blinks when the direction indicators are on.

It is important to carry out the refuelling and the maintenance operations in a wellventilated area, with the engine off. Do not smoke while refuelling or near fuel vapours, in any case avoid any contact with naked flames, sparks and any other heat source to prevent the fuel from catching fire or from exploding. Further, prevent fuel from flowing out of the fuel filler, as it could catch fire when getting in contact with the red-hot surfaces of the engine. In case some fuel has accidentally been spilt, make sure that the area has completely dried and before starting the vehicle verify that there is no fuel inside the fuel filler neck. Since petrol expands under the heat of the sun and due to the effects of sun radiation, never fill the tank to the brim. Screw the plug up carefully after refuelling. Avoid any contact of the fuel with the skin and the inhalation of vapours; do not swallow fuel or pour it from a receptacle into another by means of a tube. 42!.3-)33)/. /), Check the transmission oil level every 4000 km (2500 mi), see p. 48 (CHECKING THE TRANSMISSION OIL LEVEL AND TOPPING UP). Change the transmission oil after the first 1000 km (625 mi) and successively every 12000 km (7500 mi), see p. 49 (CHANGING THE TRANSMISSION OIL). a DO NOT DISPOSE OF FUEL IN THE ENVIRONMENT. KEEP AWAY FROM CHILDREN. Use only unleaded petrol, in conformity with the DIN 51607 standard, min. O.N. 95 (N.O.R.M.) and 85 (N.O.M.M.). FUEL TANK CAPACITY (reserve included): 13 L TANK RESERVE: 3.5 L (mechanical reserve) To refuel, proceed as follows: N Insert the key (1) in the tank plug lock (2). N Turn the key clockwise, pull and open the fuel flap. Engine oil can cause serious damage to the skin if handled every day and for long periods. Wash your hands carefully after using the oil. Do not dispose of the oil in the environment. Put it in a sealed container and take it to the filling station where you usually buy it or to an oil salvage center. In case any maintenance operation has to be carried out, it is advisable to use latex gloves. c a Use high-quality 75W-90 oil, see p. 81 (LUBRICANT CHART). use and maintenance RS 125 25 Make sure that the brake discs are neither oily nor greasy, especi a ll y a f te r ma in t en an ce or checking operations. Check that the brake cables are neither twisted nor worn out. Prevent water or dust from accidentally getting into the circuit. In case maintenance operations are to be performed on the hydraulic circuit, it is advisable to use latex gloves. If the brake fluid gets in contact with the skin or the eyes, it can cause serious irritations. Carefully wash the parts of your body that get in contact with the liquid. Consult a doctor or an oculist if the liquid gets in contact with your eyes. Do not dispose of the brake fluid in the environment. KEEP AWAY FROM CHILDREN. When using the brake fluid, take care not to spill it on the plastic or painted parts, since it can damage them. a $)3# "2!+%3 The brakes are the parts that most ensure your safety and for this reason they must always be perfectly working; check them before every trip. The brake fluid must be changed once a year by an APRILIA Official Dealer. Use brake fluid of the type specified in the lubricant chart, see p. 81 (LUBRICANT CHART). This vehicle is provided with front and rear hydraulic disc brakes. When the disc pads wear out, the level of the fluid decreases to automatically compensate for their wear. The front brake fluid tank is positioned on the right part of the handlebar, near the front brake lever coupling. The rear brake fluid tank is positioned under the upper part of the fairing, on the right side of the vehicle. Periodically check the brake fluid level in the tanks, see p. 27 (FRONT BRAKE), p. 28 (REAR BRAKE) and the wear of the pads, see p. 61 (CHECKING THE BRAKE PAD WEAR). a "2!+% &,5)$ RECOMMENDATIONS This vehicle is provided with front and rear disc brakes, with separate hydraulic circuits. The following information refers to a single braking system, but is valid for both. Sudden resistance or clearance problems on the brake lever may be due to troubles in the hydraulic system.

Check the coolant level every 1500 km (935 mi) and after long rides; change it every 24 months. The coolant is noxious: do not swallow it; if the coolant gets in contact with the skin or the eyes, it can cause serious irritations. If the coolant gets in contact with your skin or eyes, rinse with plenty of water and consult a doctor. If it is swallowed, induce vomit, rinse mouth and throat with plenty of water and consult a doctor without delay. DO NOT DISPOSE OF THE BRAKE FLUID IN THE ENVIRONMENT. KEEP AWAY FROM CHILDREN. Be careful not to spill the coolant on the red-hot parts of the engine: it may catch fire and send out invisible flames. In case maintenance operations are to be performed, it is advisable to use latex gloves. The coolant is made up of 50% water and 50% antifreeze. This mixture is ideal for most running temperatures and ensures good protection against corrosion. It is advisable to keep the same mixture also in the hot season, since in this way losses due to evaporation are reduced and it is not necessary to top up very frequently. The mineral salt deposits left in the radiator by evaporated water are thus reduced and the efficiency of the cooling system remains unchanged. If the outdoor temperature is below 0°, check the cooling circuit frequently and if necessary increase the antifreeze concentration (up to maximum 60%). For the cooling solution use distilled water, in order not to damage the engine. Do not remove the expansion tank cap when the engine is hot, since the coolant is under pressure and its temperature is high. CHECKING AND TOPPING UP a N N N Check the coolant level and top up the expansion tank with cold engine. c Stop the engine and wait until it has cooled down.

TA). a Periodically check the tyre inflation pressure at room temperature, see p. 78 (TECHNICAL DA- Change the tyre when it is worn out or in case of puncture on the tread side, if the puncture is larger than 5 mm. After repairing a tyre, have the wheels balanced. Use only tyres in the size suggested by aprilia, see p. 78 (TECHNICAL DATA). Make sure that the tyres always have their valve sealing caps on, to prevent them from suddenly going flat. Change, repair, maintenance and balancing operations are very important and should be carried out by qualified technicians with appropriate tools. For this reason, it is advisable to have the above mentioned operations carried out by an APRILIA Official Dealer or by a qualified tyre repairer. If the tyres are new, they may still be covered with a slippery film: drive carefully for the first miles. Do not oil the tyres with unsuitable fluids. If the tyres are old, even if not completely worn out, they may become hard and may not ensure good road holding. In this case, replace them. MINIMUM TREAD DEPTH LIMIT front: ............................................... 2 mm rear: ................................................ 2 mm If the tyres are hot, the measurement is not correct. Carry out the measurement especially before and after long rides. If the inflation pressure is too high, the ground unevenness cannot be dampened and is therefore transmitted to the handlebar, thus compromising the driving comfort and reducing the road holding during turns. If, on the contrary, the inflation pressure is too low, the tyre sides are under greater stress and the tyre itself may slip on the rim or it may become loose, with consequent loss of control of the vehicle. In case of sudden braking the tyres could even get out of the rims. Further, the vehicle could skid while turning. Check the surface and the wear of the tyres, since tyres in bad conditions can impair both the grip and the controllability of the vehicle.

If you have to brake, close the throttle and put on both brakes in order to obtain uniform deceleration, properly exerting pressure on the braking parts. By putting on the front brake only or the rear brake only, you reduce the braking force considerably, thus running the risk of locking one wheel and consequently losing grip. If you stop uphill, decelerate completely and use the brakes only to keep the vehicle steady. The use of the engine to keep the vehicle steady may cause the overheating of the clutch. a Before beginning to turn, slow down or brake driving at moderate and constant speed or accelerating slightly; avoid braking at the last moment: it would be very easy to skid. If the brakes are operated continuously on downhill stretches, the friction surfaces may overheat, thus reducing the braking efficiency. Exploit the engine compression and shift down by putting on both brakes intermittently. Never drive downhill with the engine off! In case of wet ground or scarce wheel grip (snow, ice, mud, etc.), drive slowly, avoiding sudden brakings or manoeuvres that could make you lose grip and fall down. a Pay the utmost attention to any obstacle or variation of the ground. Uneven roads, rails, manhole covers, indications painted on the road surface, building site metal plates become rather slippery by rain. For this reason all these obstacles have to be carefully avoided, driving smoothly and bending the vehicle as little as possible. Always use the turn indicators in time when you intend to change lane or direction, avoiding sharp and dangerous movements. Switch off the direction indicators as soon as you have changed direction. Be extremely careful when you overtake other vehicles or are overtaken. In case of rain, the water cloud created by big vehicles reduces visibility; the air shift may make you lose control of the vehicle. a
