guida sicura
BASIC SAFETY RULES
To drive the vehicle, you must satisfy
certain legal requirements (driving licence,
minimum age limit, psychophysical fitness,
insurance, vehicle licence tax, vehicle
registration, number plate, etc.).
Begin to familiarise yourself with the
vehicle by riding in low traffic areas and/or
private ground.
Certain prescribed medicines, alcohol,
drugs and psychotropic substances will
affect your riding, thereby increasing the
risk of an accident.
Be sure that you are in good
psychophysical conditions and fit for
driving and pay particular attention to
physical weariness and drowsiness.
use and maintenance Quasar 50 - 100 - 125 - 180
6
Most road accidents are caused by
inexperienced riders.
NEVER lend your vehicle to a beginner
and make sure any person borrowing your
vehicle fills the legal requirements for
driving.
Strictly observe all posted signs and
national and local road regulations.
Avoid any sudden or risky manoeuvres
that may endanger your and other people's
safety (for example: reckless manoeuvres,
speeding, etc.), and adjust your riding style
to road surface conditions, visibility, etc.
Avoid obstacles that could damage the
vehicle or make you lose control of the
vehicle.
WARNING
Always hold the handlebars with both
hands and keep both feet on the
footpegs (or on the rider's footboards),
in the correct riding position.
Do not stand up or stretch your limbs while
riding.
ONLY ORIGINALS
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 specified fuels and lubricants
indicated in the "LUBRICANT CHART"
(page58) and check engine oil,
transmission fluid and fuel levels at regular
intervals.
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 Authorised Dealer who should
carefully check the frame, handlebars,
suspensions, safety parts and all the
devices that you cannot check by yourself.
Remember to report any malfunction to the
technicians and/or mechanics to facilitate
their work.
Never use the vehicle when the amount of
damage it has suffered makes it unsafe to
ride.
Never change the position, inclination or
colour of: number plate, turn indicators,
lights and horns.
Any modification of the vehicle will result in
the invalidity of the warranty.
Making any modifications to the vehicle
and/or removing the original components
can adversely affect vehicle performance
and safety or make it illegal to ride.
Observe applicable law and all national
and local regulations concerning vehicle
equipment.
In particular, avoid any modifications apt to
enhance performance or alter the vehicle's
original specifications.
Never race with other vehicles.
use and maintenance Quasar 50 - 100 - 125 - 180

CLOTHING
Always wear and fasten your helmet
correctly before moving off. Make sure
your helmet complies with applicable
regulations, is not damaged, is the right
size and keep the visor clean.
Wear protective clothing, preferably bright
and/or reflective clothing. This will ensure
you are easily seen by other road users
and reduce the risk of an accident, besides
affording improved protection in the event
of a fall.
Wear tight-fitting clothing fastened at the
wrists and ankles; make sure no strings,
belts and ties are hanging loose; make
sure no items of clothing or other objects
can distract you or become entangled with
moving parts or with the handlebars.
use and maintenance Quasar 50 - 100 - 125 - 180
8
Do not ride with sharp or pointed objects in
your pockets as they might cause injury in
the event of a fall (this includes keys, pens,
glass vials, etc. - note that the same
applies to your passenger).
Avoid fixing bulky, heavy and/or dangerous
objects to the handlebars, mudguards and
forks - this could slow down the vehicle's
response in turns and would inevitably
affect handling.
Do not place bags that are too bulky or the
crash helmet on the vehicle sides and do
not ride with them on, because they could
hit people or obstacles, making you lose
control of the vehicle.
Do not exceed the maximum load capacity
of each luggage rack.
When the vehicle is overloaded, its stability
and its manoeuvrability can be
compromised.
Never use the vehicle in water deeper than
10 cm.
After having used the vehicle in salt water,
it is necessary to wash it with fresh water.
Never show off without respecting the
safety features.
Never unbalance the weight of your body
so to avoid that vehicle takes unusual
positions.
The vehicle should always be ridden
following the safety rules indicated in this
manual, at any time (riding uphill, downhill,
turning, etc.) and with any surface
conditions.

MAIN COMPONENTS
FUEL
WARNING
The fuel used in internal combustion
engines is highly flammable and can
become explosive under particular
conditions.
It is important to refuel and service the
vehicle in a well-ventilated area, with the
engine off. Do not smoke while refuelling
or near fuel vapours, in any case avoid
contact with naked flames, sparks and any
other heat source or source of ignition to
prevent fires or explosion.
Avoid spilling fuel, as it may ignite when in
contact with hot engine parts.
In the event of accidental spillage, make
sure that the area has completely dried
before starting the engine.
Never fill the tank to the rim, as fuel
expands from heat and when left under
direct sunlight. Tighten the filler plug
securely after refuelling.
Avoid contact with skin, do not inhale fuel
vapours; do not swallow fuel or transfer it
between different receptacles using a
hose.
DO NOT RELEASE FUEL INTO THE
ENVIRONMENT.
KEEP AWAY FROM CHILDREN.
Use only premium-grade unleaded fuel
with a minimum octane rating of 95 (RON)
and 85 (MON).
To refuel, proceed as follows:
◆ Unscrew and remove the tank plug (1).

TYRES
This vehicle is equipped with tubeless
tyres.
CAUTION Perform
maintenance operations more frequently
than the indicated intervals if you are riding
in rainy or dusty conditions, on rough road
surfaces or when the vehicle is used for
racing.
WARNING
Check the tyre inflation pressure at
room temperature before every ride.
Measuring pressure on hot tyres will
lead to inaccurate measurement.
Overinflated tyres will not absorb
bumps when riding on rough road
surfaces and resulting vibration is
transferred through the handlebar,
giving a harsh ride and reducing tyre
grip especially during cornering.
Conversely, underinflation will put more
stress on the sidewalls (1) and the tyre
may slip on the rim or even come off the
rim, leading to loss of control. The tyres
could come off the rims under harsh
braking. An underinflated tyre will put
the tyre in contact with the rim thus
cutting the tyre surface. After the first
two weeks and then every month check
tyre condition. Finally, the vehicle could
skid during cornering.
WARNING
Inspect tyre surface condition and
check for wear, as worn tyres lead to
poor road holding and handling. Some
of the tyres approved for this vehicle
are equipped with wear indicators.
There are several kinds of wear
indicators. For more information on
how to check the tyres for wear, contact
your Dealer. Visually inspect the tyres
for wear and have them changed if
worn. Have the wheels balanced after
each tyre repair.
WARNING
Use tyres of the specified type and
model recommended by the
manufacturer. Using other than
specified tyres may adversely affect
handling.
Do not install tube tyres on tubeless
tyre rims or vice versa.
Always check that the caps are in place
on the valves, or the tyres may deflate
suddenly.
Tyre replacement and repair, and wheel
servicing and balancing are delicate
operations that should be carried out
using adequate tools and are best left to
experienced mechanics.
Have your tyres and wheels serviced at
an Aprilia Authorised Dealer
or a specialised tyre repairer.
New tyres may be coated with an oily
film: ride carefully until covering
several kilometres. Old tyres, even if
not completely worn down, may
become hard and provide poor grip.
If so, have them replaced.

DISC BRAKES
WARNING
The brakes are critical to your safety
and must always be kept in sleek running order. Check the brakes before
each ride.
A dirty disc will soil the pads, leading to
loss of braking efficiency. Dirty pads
must be replaced, while dirty discs
must be cleaned with a high-quality degreaser.
Have brake fluid changed at an Aprilia
Authorised Dealerevery two years.
CHECKING BRAKE FLUID LEVEL
CAUTION
Fluid reservoir (1) is under rear right
wheelhouse.
CAUTION Position the vehicle
on firm and flat ground.
◆ Make sure that the fluid contained in the
reservoir exceeds the "MIN" mark
stamped on the reservoir.
MIN = minimum level.
WARNING
Do not use the vehicle if the braking
system is leaking fluid.
CAUTION
Do not use the vehicle if the fluid is below the “MIN” mark.
CAUTION
Brake fluid level decreases as the brake
pads wear down.
Should the level be too low:
◆ Check the brake discs and pads for
wear, see page 27 (CHECKING THE
BRAKE PADS FOR WEAR)
If the pads and/or the disc do not need replacing:
◆ Contact an Aprilia Authorised Dealer
that will top up the fluid.
WARNING
Check the brake for proper operation.
When the brake lever has exceeding
travel or if you notice a loss of braking,
contact an Aprilia Authorised Dealer.The braking system may need bleeding.
1
CHECKING THE BRAKE PADS FOR WEAR
Carefully read page 26 (BRAKE FLUID recommendations), page 26 (DISC
BRAKES) and page 34 (MAINTENANCE).
Periodically check brake pad wear. The
rate at which brake pads will wear depends
on vehicle usage, riding style and road surface condition.
Outlined below is a quick brake pad inspection procedure:
◆ Visually check between brake disc and
pads, check both pads (1) looking from
the bottom at the rear end.
◆ Should friction material (of even one pad
only) be worn down to 1.5 mm of thickness, have both pads replaced.

persons or animals.
RUNNING-IN
Correct engine running-is essential to ensuring proper performance and durability.
Vary speed frequently during the runningin period.
This will allow engine parts to be alternately
loaded and unloaded, allowing them to cool
down when unloaded.
While it is important to put some stress on
engine components during running-in, it is
equally important to avoid extreme load
conditions.
CAUTION It is possible to reach
the best performance of the vehicle only
when the first 20 l of fuel have been used.
3
Follow these recommendations:
◆ Do not open the throttle harshly and
completely when engine is running at low
rpm.
◆ During the first 4 hours of operation, use
the brakes gently and avoid harsh, prolonged braking. This will help the brake
pads bed in properly against the brake
discs and block friction material to settle
onto brake drums.
STOPPING
WARNING
If you can, do not stop or slow down
suddenly and avoid limit-braking.
◆ Release of the throttle.
◆ Gradually put on the brakes until the ve-
hicle stops.
◆ If you need to stop only briefly, keep at
least one brake applied.
CAUTION Use,
whenever possible, the brake pedal that applies front and rear brakes at the same time
thanks to a distribution frame, thus ensuring
quick deceleration without the risk of locking
the wheel.

CHECKING CHAIN AND SPROCKETS
FOR WEAR
Visually inspect chain, front and rear
sprockets looking for:
√ damaged chain rollers;
√ loose chain link pins;
√ dry, rusty, warped or seized links;
√ exceeding wear;
√ exceedingly worn or damaged sprocket
teeth.
CAUTION
If chain rollers are damaged and/or
chain link pins are loose, renew the
drive chain and the front and rear
sprockets as a set.
Lubricate the chain frequently,
especially if you find any dry or rusty
parts.
Change the chain if some links are
warped or have seized.
If this is not possible, have the chain
replaced at an Aprilia Authorised
Dealer.
CLEANING AND LUBRICATION
Never wash the drive chain using steam
cleaners, high-pressure water nozzles or
highly flammable solvents.
◆ Wash the drive chain with fuel oil or
kerosene. If the chain tends to become
rusty quickly, service more frequently.
◆ Wash and dry the chain, lubricate it with
recommended grease (see lubricant
table).
CAUTION Do not ride when you
have only just lubricated the chain.
Centrifugal force would cause the newly
applied lubricant to fly all over adjacent
vehicle parts.

CLEANING
CAUTION
If the vehicle is used on sandy roads, use
fresh water to wash the vehicle immediately after use. Salt water causes rust and early wear. Clean the vehicle frequently if it is
used in particular areas or conditions,
such as:
√ Pollution (urban and industrial areas)
√ High salinity and humidity (sea areas,
hot and damp climates).
√ Seasonal/environmental conditions
(road salt and chemicals spread on the
roads in the wintertime).
√ Make sure to clean off any industrial res-
idue and pollutants, tar , dead insects,
bird droppings, etc. from the body panels
and fairings.
√ Avoid parking the vehicle under trees.
Resins, fruits or leaves falling from the
trees may contain aggressive chemical
substances that may damage the paintwork.
WARNING
After the vehicle has been washed,
braking efficiency could be temporarily
impaired because the friction surfaces
of the braking systems may still be wet.
Ride carefully as braking distance will
be longer.
Operate the brakes repeatedly to restore normal operation.
Perform the recommended pre-ride
checks, see page 29 (PRE-RIDE
CHECKS CHART)
To clean off dirt and mud from painted surfaces, soften caked dirt with a low-pressure
water jet. Sponge off using a car body
sponge soaked in a car body shampoo and
water solution (2-4% parts of shampoo).
Then rinse with plenty of water and dry with
chamois leather. Clean the outer parts of
the engine using a degreaser, small brushes and cloth.
CAUTION
To clean the lights, use a sponge
soaked with water and a mild detergent,
rubbing the surfaces delicately and
rinsing frequently with plenty of water.
Wash the vehicle thoroughly before applying silicone wax.
Do not polish matt-painted surfaces
with polishing paste.
use and maintenance Quasar 50 - 100 - 125 - 180
53
Do not wash the vehicle under the sun,
especially in the summertime, when the
body is still warm, as the shampoo will
dry before you can rinse it away and
could damage the paint.
Do not use liquids at a temperature
higher than 40°C to clean the plastic
components of the vehicle.
CAUTION
Do not aim high-pressure water/air jets
or steam jets at the following parts:
wheel hubs, controls on the right and
left side of the handlebar, bearings,
brake master cylinders, instruments
and indicators, silencer, glove/tool kit
compartment, ignition switch, cooler or
radiator fins, fuel filler plug, lights and
electric connections.
Do not use alcohol, petrol or solvents to
clean rubber and plastic parts and the
seat; use water and mild soap only.
WARNING
Do not apply protection waxes to the
seat, or it may become slippery.
LONG PERIODS OF INACTIVITY
When the vehicle is to remain unused for
long periods, some precautions are necessary to avoid damage.
Do not postpone necessary repairs or you
could forget them when you take the vehicle out of storage; a general check up is
also recommended.
Proceed as follows:
◆ Remove the battery, see page 45 (RE-
MOVING THE BATTERY)
◆ Wash and dry the vehicle, see page 53

haust pipe opening to keep moisture out.
◆ Cover the vehicle avoiding plastic or wa-
terproof covers.
AFTER STORAGE
CAUTION Remove the plastic
bag from the exhaust pipe.
◆ Remove the cover and clean the vehicle,
see page 53 (CLEANING).
◆ Check battery charge, see page 46
