BASIC SAFETY RULES Fig. 1 To drive the vehicle it is necessary to be in possession of all the requirements prescribed by law (driving licence, minimum age, psychophysical ability, insurance, state taxes, vehicle registration, number plate, etc.). 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.
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. Fig. 3 The driver should pay attention and avoid distractions caused by people, things and movements (never smoke, eat, drink, read, etc.
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 Concessionario Ufficiale aprilia 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.
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.
ACCESSORIES Fig. 9 Fig. 10 10 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.
LOAD Be careful and moderate when loading your luggage. Keep any luggage loaded as close as possible to the center of gravity of the vehicle and distribute the load uniformly on both sides, in order to reduce umbalance to the minimum. Furthermore, make sure that the load is firmly secured to the vehicle, especially during long trips.

Carry out the maintenance operations more frequently if you use the vehicle in rainy and dusty areas or on uneven ground.
IDENTIFICATION DATA It is a good rule to write down the frame and engine numbers in the space provided in this manual. The frame number can be used for the purchase of spare parts. Do not alter the identification numbers if you do not want to incur severe penal and administrative sanctions. In particular, the alteration of the frame number results in the immediate invalidity of the guarantee. Fig. 42 FRAME NUMBER (Fig. 42) The frame number is stamped on the left side of the steering head.
2 CHECKING THE GEAR OIL LEVEL (Fig. 44) ◆ ◆ 1 3 Fig. 44 In case of oil leakages or malfunctions, contact your aprilia Official Dealer. DO NOT DISPOSE OF OIL IN THE ENVIRONMENT. ◆ Hold the vehicle in an upright position with respect to the ground. Remove the checking screw (1) (right side cover): the oil level is correct if it reaches the bottom edge of the hole when the vehicle in an upright position. If necessary, top up through the filler hole (2). GEAR OIL REPLACEMENT (Fig.
CLUTCH ADJUSTMENT (Fig. 45-46) This model is equipped with two devices for adjusting the length of the clutch cable. Check the correct adjustment of the clutch cable from time to time, ensuring that the idle stroke of the control lever is from 3 ÷ 4 mm (Fig. 45). If this distance is not correct, turn the control lever adjuster (1) or the adjuster on the motor cover (Fig. 46).
SEPARATE LUBRICATION (Fig. 47) Top up the mixer oil tank every 500 km. The vehicle has a separate lubrication system which includes an mixer oil tank (Fig. 47) (1,3 l with a reserve of 0,5 l ) and a variable-capacity oil supply pump (the capacity varies according to the number of revs of the motor and the opening of the throttle). When the oil reaches reserve level, this is indicated by the coming on of the mixer oil reserve warning light “ “. Fig.
◆ ◆ Unscrew the drainage screw (1) and at the same time completely rotate the pump control lever (2) until the oil drains off, then tighten the screw again. Keep the pump lever rotated until all traces of air bubbles have completely disappeared from the carburettor supply pipe. For greater safety we advise using up all the blended fuel in the tank before refilling with only premium grade petrol (see “TECHNICAL FEATURES”).
◆ ◆ Lock the brake adjuster (2) by means of the lock nut (1). Unscrew the pump control rod (4) and restore the clearance between the brake adjuster and the stroke point. Make sure that some clearance is present between brake rod and master cylinder. This will avoid brake to be left unintentionally operated with a consequent early wear of braking system parts. 4 3 1 2 Fig. 49 ADJUSTING THE REAR BRAKE (Fig. 49) The brake pedal is positioned ergonomically during the assembly phase.
CHECKING THE BRAKE PAD WEAR (Fig. 50) Check brake pads for wear every 2,000 km. In case of off-road use, with mud or sand, check brake pads after every ride. The pads present a groove that must always be visible. both. Fig. 50 The following information refer to a single braking system, but are valid for Disc brake pads wear depends on use, riding style and road surface. Check brake pads for wear, especially before every trip.
◆ From above, on the rear part, for rear brake caliper. The excessive wear of the friction material would cause the contact of the pad metal support with the disc, with consequent metallic noise and production of sparks from the caliper; braking efficiency, safety and soundness of the disc would thus be negatively affected. Should the groove have worn out (i.e. friction material 1.5 mm thick), change both pads: √ For the front brake caliper have both pads changed.
ADJUSTING THE REAR SUSPENSION (Fig. 52) The rear suspension comprises a single springshock absorber unit and a lever unit with A.P.S. The standard rear suspension is suitable for a driver weighing about 75 kg. If your weight or your needs are different, work on the length of the shock absorber spring, by acting on the nut (1) to restore the right driving position. To check this position: With the vehicle in an upright position, without the rider and prop stand, measure the distance (2-3).
CHAIN ADJUSTMENT (Fig. 53) ◆ ◆ Stand the vehicle in an upright position and completely extend the rear suspension. Check that the vertical movement in the lower part of the chain, at a point mid-way between the pinion and the crown, is about 30 mm. If this distance is not correct, proceed as follows: Loosen the rear wheel pin fastening nut. ◆ For the wheel centering: Make sure that on both sides the fixed reference on the rear fork corresponds to the number indicated on the chain tightener. ◆ ◆ 30 Fig.
CHAIN LUBRICATION (Fig. 54) Proceed to chain lubrication frequently (see ≈LUBRICANT CHART∆), every 4,000 km, every time the vehicle is used off-road on mud or sand. Fig. 54 CHAIN CHECKING (Fig. 55) From time to time check the wear condition of the chain; make sure that it is not too loose and that there are no angles or seized links. If any faults are found, change the chain.
COOLANT CHECKING Do not use the vehicle if the coolant is below the minimum allowed level. Do not remove the radiator plug when the engine is hot, since the coolant is under pressure and its temperature is high. If it gets in contact with the skin or with clothes it can cause severe burns and/or damages. Every 2000 km or after using the vehicle in difficult conditions, check the coolant level with cold engine; change the coolant every two years.
CHECKING AND TOPPING UP (Fig. 56) ◆ Let the engine cool down for a few minutes. ◆ Keep the vehicle in vertical position. ◆ Make sure that the level of the fluid contained in the expansion tank (see figure) is included between 1/4th and 3/4ths of the capacity of the expansion tank itself. ◆ If not, remove the filling plug (see figure). Be careful not to confuse the oil mixer tank with the expansion tank. ◆ Top up until the fluid level reaches about 3/4ths of the expansion tank.
REGOLAZIONE DEL MINIMO (Fig. 57) Adjust the idling every time it is irregular. Fig. 57 To carry out this operation, proceed as follows: ◆ Warm the engine up until it reaches the normal running temperature. ◆ Set the gear in neutral position (neutral indicator warning light ≈ ∆ comes on). ◆ Position the vehicle on the stand. ◆ Connect an electronic revolution counter to the spark plug cable. ◆ Act on the adjusting screw positioned on the carburettor.
ADJUSTING THE ACCELERATOR CONTROL (Fig. 58) The slack of the accelerator control must be about 23 mm, measured on the the twist grip. To adjust the slack, proceed as follows: ◆ Remove the protection element (1). ◆ Release the nut (2). ◆ Act on the adjuster (3) placed at the beginning of the accelerator control cable. ◆ Once you have carried out the adjustment, lock the nut (2) and put back the protection cover (1). Fig.
ELECTRICAL SYSTEM For battery efficiency (Fig. 59) it is very important that the correct load of acid be observed and that maintenance be carried out properly. If the following instructions are scrupulously observed, the battery life will be considerably prolonged. Fig.
BATTERY MAINTENANCE ◆ It is important to check the level of the electrolyte at least once a month or even more frequently during the summer months. The level should be kept between the ≈MIN∆ and ≈MAX∆ marks and topped up from time to time WITH DISTILLED WATER ONLY. When checking the liquid level, ensure that the breather pipe is properly connected to the battery. When the plates remain uncovered, an irreversible degeneration process begins. 60 ◆ Battery shall be always kept FULLY CHARGED.
FUSE REPLACEMENT (Fig. 60) The fuse (7,5 A) is positioned under the saddle. If any device ceases to operate, check the fuse that protects the circuit. If the fuse is burnt-out the filament will be broken. Before replacing the fuse, look, if possible, for the cause of the fault. Then replace the fuse with another of the same type. Never close the circuit with material other than the fuse. Fig.
