aCAUTION
If the symb ol HIL (9B) is displayed during the normal running of the en­gine, this means that the electronic unit has detected an anomaly. In many cas­es, the engine keeps running with re­duced performance levels; immediately contact your Local APRILIADealer
.
aWARNING
Avoid opening and clo sing the throttle repeatedly and continuously. Failure to head this warning can cause you to ac­cidentally lose control of your vehicle.
When you have to brake, close the throttle and apply both brakes simulta­neously in order to obtain the best brake performance.
By applying only the front brake or only the rear brake, you re duce the braking performance considerably and run the risk of locking up one wheel which can cause an upset and subsequent serious injury or even death.
If you stop on an up hill, us e brakes only to slow the vehicle and to keep it in place. Slipping the clutch to keep the vehicle in one place on an uphill grade will very quickly ruin the clutch and overheat the engine.
Before enteri ng a turn, slow down, us­ing the brakes and the engine, to a con­stant speed and then accelerate slightly

through the turn. Av oid braking at the last moment. Thi s can cause you to lose control of your vehicle.
If the brakes are operated continuously on downhill grades, the discs and pads will overheat, reducing the braking effi­ciency. Use engine compre ssion and downshift to retard your vehicle while going downhill. Use the brakes as little as possible to maintain a safe speed.
Never coast downhill with the e ngine off and/or the clutch disengag ed or the transmission in neutral.
On roads that are wet or covered with snow, ice or mud, ride very slowly, avoiding braking or accelerating or ma­neuvering quickly. Hold the handlebars firmly.
Failure to heed these warnings can cause an upset with su bsequent seri­ous injury or death.
Pay very close attention to any obsta­cles or variations of the road surface. Uneven roads, rails, manhole covers, painted traffic stripes, traffic dots all be ­come slippery when wet. Avoid partic u­larly steel pl ates which are som etimes used during r oad maintenanc e. They become more slippery than ice once they are wet by rain. If you must ride on such surfaces, decrease your speed and operate the throttle, brakes and steering very gently.
Always use the turn signals any time you intend to change lanes or change direction, and avoid sudden or abrupt turning.

Switch off the direction indicators as soon as you have changed direction.
Overtake and pass only with care, espe­cially in rainy weather when a water cloud created by larger vehicles reduces visibility and the slip stream could cause you to lose control of your vehicle.
25..).').
The internal parts of the engine and trans­mission must be properly run-in to ensure their long life and dependable operation.
If possible, while breaking in your vehicle, ride on hilly roads a nd/ or roa ds w it h many curves so that the engine and transmis­sion undergo lots of speed changes. It i s also important that, during the r un-in peri­od, the suspension and brak es be treated gently to allow the mating parts to bed.
Therefore, avoid hard braking, high speeds or very bumpy roads during the break in period.
NOTE Only after the first 937 mi (1500
km) of running-in you can expect the best performance from the vehicle.
During break in, obey the following rules:
Do not open the throttle abruptly or fully at low engine speed. This rule applies even after break in has been completed.
During the first 62 mi (100 km), apply the brakes with caution, avoid sudden and prolonged braking. This ensures correct bedding in of the pads on the discs.
During the first 625 mi (1,000 km), never
exceed 6,000 rpm.
aWARNING
After the vehicle has been operated for 625 mi (1,000 km) perform the “checking operations shown in column After run­ning-in of the REGULAR SERVICE IN­TERVALS CHART, see p. 74. Rectify any faults found. Failur e to heed this warn­ing could lead to damage to your vehicle or engine s eizure or o ther malfun ction which could cause an upset and lead to serious injury or even death.
Between the first 625 mi (1,000 km) and 937 mi (1,500 km) drive more briskly, changing speed and using maximum ac­celeration for only a few seconds. Never exceed 7,500 rpm.
After the first 937 mi (1,500 km) if you have followed the above break in sched­ule, the engine should be fully broken in, and will deliver maxi mum performance. However, never exceed the ma ximum al­lowed rpm (10,500 rpm).

Before beginning any main tenance op­eration or any inspection of the vehicle, stop the engine, remove the key (1) from the ignition swi tch (2), wait until the engine and the e xhaust syst em have cooled down and if possible lift the ve­hicle by means of the pro per equip­ment, on firm and flat ground.
Before proceeding, make sure that the room in which you are working is prop­erly ventilated.
Be careful to avoid hot parts of the en­gine and exhaust system. They are hot enough to cause serious burns.
Avoid the temptation to hold any part of the vehicle in your mouth . The c oati ngs and platings used are, in some cases, toxic.
aCAUTION
In general, reas sembly is perfor med in the reverse order of the disassembly in­structions given here.
For some maintenance operations, es­pecially those in which your hands are likely to come in contact with coolant, or engine oil, or gasoline, or bra ke fl uid, it is advisable to use thin disposable gloves, such as thos e made of latex, rubber or nitrile.
The routine maintenance operations de­scribed in this manual can usually be per­formed by the user. However, in some cases, specific tools a nd technical exper­tise may be required.
Do not hesitate to contact your Local aprilia Dealer who has all the latest factory infor­mation and tools to properly service your vehicle. Remember that many s ervic e opera tions, if done improperly, can be very hazardous. If you have any quest ions abou t your abili ty to carry out the operations described here, contact yo ur Local aprilia Dealer.
In all cases, personally carry out the “pre- liminary checking operations after any maintenance, see p.61 (PRELIMINARY CHECKING OPERATIONS).
aWARNING
Remember that tightening torq ue of all fasteners on the wheels, brakes, axles, suspension are extremel y important to ensure safety, and must be maintained at the prescribed values.
Check the tightening torques of the fas­teners regularly, and always use a torque wrench when installing them.
Failure to adhere to this warning could cause the loosening and subsequent loss of critical f asteners, which could cause a wheel to lock or cause other handling prob lems with consequent overturning, and the risk of serious inju­ry or even death.
aWARNING
Fasteners mu st be neither over tight­ened or undertightened. If they are overtightened, the threads ma y be dam ­aged and the fa steners will be de­stroyed, whereas if they are undertight­ened, they can vibrate and become lost. Obviously, under these circumstances, a serious accident with resultant seri­ous injury or death could ensue.
aCAUTION
After the first 6 25 mi (1,000 km) and suc­cessively every 4,687 mi (7,500 km), the word SERVICE (3) appear s on the ri ght display.

It is critical to the safe operation of your vehicle that the proper lubricants, mai n­tained at the proper levels, are used. Failure to heed this warning can lead to an engine seizure wit h subseq uent acci­dent, serious injury or death.
aWARNING
Remember that the tightening torque of all fasteners on the wheels, brakes, ax­les, and other components of the sus­pension system is very important to en­sure the safety of the vehicle, and must be kept at the prescribed values. Check the tightening torque of the fas­teners regularly, and always use a torque wrench when reinstalling them. Failure to comply with this warning could allow one of these compon ents to be lost which could lock a wheel or cause other handling pro blems with consequent overturning and risk of se­rious injury or even death.
CHECKING
NOTE Positi on the vehicle on firm a nd
flat ground.
aCAUTION
The engine oil level must be checked with warm engine. If the check is carried out with cold en­gine, the oil level may temporarily lower below the “MIN” mark.
This is not a problem, provided that the engine oil pressure warning light LED
j” does not come on, see p. 30 (IN-
STRUMENTS AND INDICATORS TA­BLE).
aWAR NING
Exhaust gases co ntain carbon monox­ide, which is extremely poisonous if in­haled. Do not start the engine in closed or bad­ly-ventilated rooms. Failure to observe this warning may cause loss of consciousness or even lead to death by asphyxia.
Check the oil when the engine is warm, having been ridden for at least 10 mi (16 km).
NOTE If the engine is cold, warm it up
for riding, preferably on a hilly road, for ap­proximately 10 mi (16 km) before checking the oil.
Stop the engine before checking the oil.
aWARNING
Should your vehicle overturn, it will leak gasoline, which is extrem ely flamm able. Flames or sparks may cause a fire, which could destroy not on ly the vehi­cle, but also the bu ilding in which it is located, and cause serious injuries or even death.
Keep the vehicle in vertical position, with the two wheels resting on the ground.
NOTE If yo u attemp t to chec k the oil with
the vehicle leaned in either direction from the vertical, your measurement w ill be in­accurate.
NOTE If the engine oil tank is dirty, wipe

ADJUSTING THE FRONT FORK
The front fork is adjusted at the factory to suit most riding conditions for most riders. However, it is pos sible to adjust the fork s et­ting to your preference, and to accommo­date the full range of operating conditions that the vehicle is intended to be used for.
aCAUTION
When adjusting the fr ont fork, always start from the most rigid setting. Do not rotate adjusters (1) and (2) beyond their limit position, to avoid damaging the threads.
Use the notches (1) and (2) provided on the adjusters as refere nce ma rks for the adjustment of hydraulic damping on ex­tension and hydraulic damping on com­pression.
Turn the adjusters (1) and (2) 1/8 turn at a time and turn the a djus ting nut (3) one notch at a time. Then, test the ve hicle on the road, to ensure you have ob­tained the optimal adjustment.
Make sure that the spring preload and hydraulic damping, both on extension and compression, is the same for both sides. A different shock absorber set­ting on the left and right side will de­crease the stability of the vehicle.
When the spring preload is increased, it is necessary to also increase the hy­draulic damping, both on extension and compression, to avoid a jerky unsteady shock action while riding.

The rear suspension consists of a hydrau­lic shock absorber - spring unit, which is mounted to the frame with a uniball, and to the swinging arm by means of a system of levers.
The ride height of the rear of the vehicle can be set using the spring preload adjust­ing ring nut (3) and locking ri ng nut, (4). The rear suspension can be tuned by ad­justing the extensi on damping with a spring adjuster (1), the damping on compression can be adjusted by a knob (2).
ADJUSTING THE REAR SHOCK ABSORBER
The rear shock absorber is set at the facto­ry to satisfy most ridin g conditi ons, at either low or high speed, and with e ithe r a li ght or full load. However, it is pos sible to tu ne the suspension to y our prefe rence by u sing the above mentioned adjustments.
aCAU TION
When adjusting the rear shock absorber, always start from the stiffest position. This is the fully clockwise position of the extension damper adjusti ng screw (1) and the compression damper knob (2).
Do not rotate the extension damper ad­justment screw (1) beyond its limit , this will damage the screw and destroy your shock absorber.
Always make sure, when adjusting screw (1), that it clicks in to an adjust­ment notch, and is not at a position inter­mediate between adjustment notches.
The distance between the top of the ad­justment ring and the top of the threads must not exc eed 1.10 ± 0.2 0 in (28 ± 5 mm). Adjusting the nut further down on the shock will compress the spring ex­cessively, and result in an uneven bumpy ride. Also, it will be impossible to adequately adjust the extension damp­ing using screw (1).
Loosen the locking rin g nu t (4) b y m ean s of the appropriate spanner wrench.
Adjust th e adjus ting ri ng nut (3) (see fig­ure).
If necessary, adjust the extension damp­ing screw (1) (see table p. 85).
Once the ride height has been properly adjusted, tighten the lock ring nut (4) completely.
Slightly loosen the lock nut (5).
Rotate the adjuster (6) one tu rn at a time so that the adjusting screw (1) faces out to the left side of the vehicle.
Using the appropriate wrench, turn the adjuster ( 6) (whi ch adjust s the ce nter to center distance of the shock absorber unit) (see table p. 85).

NOTE Adjust the spring preload and the
extension damping according to t he vehi­cle use. When the spring preload is in­creased, it is also necessary to increase the extension damping in order to avoid a bumpy uneven ride. Especially at hi gher preload setti ngs, it is advisable to use full extension damping (screw (1) fully clockwise) or only a couple of clicks clockwise, to avoid a bumpy un­even ride. If necessa ry, c on tac t y our L oc al aprilia Dealer.
Never remove the plug (7) o r attempt to ad­just the valve covered by it. This may cause nitrogen to escape which will de­stroy the function of the shock absorber and could upset the handling of your vehi­cle, leading to an ac ciden t with subse quent injury or even death.
Never exceed 2-3 clicks with the extension damping adjustment (1) or 5-6 cli cks with the compression dampi ng a dju stmen t kn ob (2), or one turn with the preload adjusting nut (3) at any given ad justment attempt. Ride the vehicle for more than just a few miles on the road between each adjust­ment, to determine the adjustments most suitable to your use.
