Exhaust fumes consist of carbon mon­oxide, an extremely harmful substance
if inhaled.
Avoid starting the engine in closed spac­es or anywhere with poor ventilation.
Failure to follow this recommendation
may result in loss of senses and even
death by asphyxia.

Battery

DANGER

The battery releases explosive gases;

keep away from sparks and free ames.

Do not smoke. When recharging the bat­tery, make sure there is sufcient air cir­culation in the area.

SAFE DRIVING

This paragraph offers some suggestions for
driving/riding safely.

ACCELERATION. Accelerating and decel­erating repeatedly without true need may
cause loss of vehicle control and result in
fall, with serious consequences for yourself,
for others, and for the vehicle.

BRAKING. To reduce speed in a uniform,
optimal manner:

- Decelerate and always use both brakes,
suitably dosing the amount of force ap­plied on the brake levers;

- Avoid close braking whenever possible.

Using only one of the brakes:

- Reduces braking force;

- Risks locking the braking wheel;

- Contributes to loss of adherence and to
the possibility of falling, with serious con­sequences for themselves and for oth­ers, as well as for the vehicle.

BRAKING IN ASCENT. Decelerate com­pletely and use both brakes to keep the ve­hicle in place.
Using motion force (using the accelerator)
to keep the vehicle in place causes anom­alous overheating of the engine and of the
clutch.
Keeping the vehicle in place using only
physical strength may cause loss of bal­ance and fall, with serious consequences
for yourself, for others and for the vehicle.

VENT 125 Baja + Baja RR / VENT 125 Derapage + Derapage RR

7use and maintenance manual

FACING AND RIDING A
CURVE. Do not ride into a curve at high

speed.

Donotunderestimatethedifcultyinvolved

in negotiating a curve; slow down before
facing it.
When you see a curve up ahead, reduce
your speed by decelerating and then brak­ing. Negotiate the curve at constant speed
or at moderate acceleration, being careful
not to lose adherence with the terrain or
control of the vehicle. If it is necessary to
use the brakes, do it with moderation and
attention.

NEGOTIATING DESCENTS: Never ride
the vehicle with the engine off in descents.
Using only the brakes when riding down a
slope causes overheat in the friction materi­al (brake linings or shoes) and consequent­ly reduces brake effectiveness.
Combine the use of brakes and the com­pression of engine power (scaling the shifts
correctly).

DRIVING WHEN VISIBILITY IS POOR. It is
obviously not advisable to drive/ride when
visibility is poor (due to rain, fog, mist etc);
if possible, it is always better to stop and
wait until visibility conditions improve before
resuming your trip.

DRIVING/RIDING WHEN ROAD ADHER­ENCE IS POOR.

Whenever possible, avoid driving/riding
in such conditions (snow, ice, mud etc). If

necessary, proceed at moderate speed and
avoid sudden manoeuvres; always brake
with caution so as to avoid losing control of
the vehicle.

OBSTACLES AND TRAPS ON THE
ROAD.

Disconnected roads, manholes, sudden
depressions, bumps, rail tracks, road signs
painted over, metal slabs belonging to build­ing sites along the road, may all be slippery
or otherwise jeopardise, even if only tempo­rarily, vehicle stability, causing falls with se­rious consequences for yourself, for others
and for the vehicle.

CHANGING LANES OR DIRECTION. Al­ways activate the blinkers when changing
lanes or direction, and carry out the ma­noeuvres with regularity.
Turn off the blinkers after use.

OVERT AKE CAREFULLY Whenever over­taking another vehicle or when you are
being overtaken yourself, be particularly
attentive. Water splashes when the road
is wet and the slipstream caused by the
motion of large vehicles can cause loss of
control of the vehicle and the possibility of
falling, with serious consequences for your­self, for others and for the vehicle.

WARNING

Always follow the recommended indica­tions when driving/riding.

PARKING

DANGER

Accidentally falling from the vehicle can
cause:

- Fuel leaking from the tank, resulting

in re hazard;

- Cooling uid leaks;

- Engine oil leaks;

- Damages to people, things and the ve­hicle itself.

To avoid accidental falls with the vehicle,

choose asolid,atterrain and an area of

suitable size for the vehicle and for parking
manoeuvres.

DANGER

Make sure the terrain is not exceedingly
inclined.
Always check the motorbike for stability
after lowering it on its kickstand.

If you must park on inclined terrain, park
your motorbike facing uphill, so that its
weight will keep the kickstand in place and
prevent it from caving in.

- Do not leave the vehicle sideways on the
ground or leaning on walls, fences, hand­rails etc.

- The vehicle must always be parked on its
kickstand.

8 use and maintenance manual

VENT 125 Baja + Baja RR / VENT 125 Derapage + Derapage RR

DANGER

The parked vehicle, and in particular its

overheated parts, must not be a hazard

for children, people or animals. NEVER
leave the vehicle parked with the engine
running.

NOTE: The kickstand is designed to sustain

the combined weight of vehicle and luggage.

- Always use the steering lock.

WARNING

Avoid parking or lounging beneath
plants or trees.

During some seasons, certain plants and
trees drop or release residues, resin, fruits
or leaves containing substances that can
damage the vehicle (especially its body).

IDENTIFICATION

Every request made to the dealer must be
accompanied by the V.I.N. of the vehicle in
question, so that the dealer can recognise
the vehicle and meet your demands.

INSTRUCTIONS TO USE THE
VEHICLE

General checks prior to use

Every time you are about to ride your mo­torcycle, go through this checklist:

- Rotate the start key to the ON position
and make sure the display lights up;

- Turn on the high beam and make sure its
warning light is on;

- Turn on the blinkers and make sure their
relative warning lights are on;

- Pull the front brake lever and press the
combined brake pedal; make sure the
rear stop light turns on;

- Check fuel and engine oil levels;

- Checkthebrakeuidlevelinitstank;

- Checkthecoolinguidlevel;

- Make sure the handlebar is working by
turning it all the way to the right and to
the left;

- Check pressure in the tyres;

- Make sure tension in the chain is ade­quate.

NOTE: For the inspection operations,
please consult their relative paragraphs.

Climbing on and off the vehicle

Pay attention to the instructions below.
They have the goal of keeping the pilot or
the passenger from falling from the vehicle
and/or the vehicle itself from toppling, which
would result in damages
to people, things and the vehicle itself.

- Only climb on and off the vehicle if you
have freedom of movement; your hands,
in particular, must not be holding objects,
such as helmet, gloves or glasses.

Climbing on the bike

- With the bike on the side kickstand, the
pilot must climb on the motorbike from
its left side, with both hands holding the
handlebar.

- Once the pilot is on the bike, lift the bike;
the side kickstand will automatically lift
as well.

DANGER

Make sure the side kickstand is fully lift­ed.

WARNING

Do not place the pilot’s or the passen­ger’s weight on the side kickstand.

NOTE: If you are unable to rest both your
feet on the ground on both sides of the bike,

rm your right foot on the ground and keep

the left one ready to offer support.

- The passenger must extract the rear
footrests and climb from the left side
of the bike, using the left footrest while
holding on to the pilot.

20 use and maintenance manual

VENT 125 Baja + Baja RR / VENT 125 Derapage + Derapage RR

Climbing off the bike

- First of all, the passenger must climb off the
left side of the bike, using the left footrest.

- Once on the ground, the passenger must
push the rear footrests back in.

- The pilotmustkeep his/herhands rmon

the handlebar and climb off the left side of
the motorcycle, resting his/her left foot on
the ground and lifting his/her right leg.

- Once on the ground, lower the kickstand
and make sure the motorcycle is resting
its weight on it (for kickstand operations,
please read the “Side kickstand” chapter).

Break-in

Breaking in is crucial for the proper working
and duration of the engine.

The break-in means the rst kilometres

covered.
During break-in, it is necessary to follow
certain rules to prepare the parts of the en­gine and of the vehicle itself for the maxi­mum performance to be demanded later on
(after the break-in).

toexceed andnottostressinsufciently;in

both cases the engine and parts of the vehi­cle might suffer.
ITINERARIES Do not strain engine, brakes
and suspensions in mountain roads.
Give preference to roads with curves and
moderate hills, where the engine, the brakes
and the suspensions can alternate periods
under stress and periods with little or no
stress at all.
SPEED Always change the speed gradual­ly, without sudden, complete accelerations.
Complete acceleration is allowed, but DO
NOT ride for long distances with the acceler­ator knob fully turned (full regime).
BRAKING New brake linings. In order to be
fully operative, the friction surface of brake
linings must be broken in, so it adheres
perfectly to the disk when braking. A good
break-in requires about 200 km (125 miles)
of urban distance. During this period, go for
longer braking distances and use the brake
lever with more intensity . Avoid sudden, long
brakes.

Adjusting rear-view mirrors

DANGER

Never ride the vehicle with the rear-view
mirrors rotated incorrectly.
Before you get going, always make sure
the mirrors are in their correct position
and adjusted accordingly.

- Climb on to the vehicle, to the pilot posi­tion.

- Use the joint (1) to regulate mirror height
(2) and the joint (3) to adjust inclination.

NOTE: Make sure you, as pilot, can prop­erly see the rear part of the road from your
sitting position.

DANGER

Always adjust the mirrors with the mo­torcycle standing still.

Rules for a good break-in

These rules are only suggestions to help the
rider break in the motorcycle properly. Fail­ing to follow them may not result in immedi-

Removing the wheels

WARNING

An inexperienced user may nd it dif-

cult and complex to disassemble and

reassemble the front wheel.
In case of need, contact a VENT Dealer.
If you do wish to do it yourself, follow
these instructions.

NOTE: When disassembling and reassem­bling the wheel, be careful not to damage
the brake tubes, disk and linings.
To disassemble and reassemble, wear

work gloves that ensure suitable protection
for ngers and hands.

Disassembling the front wheel

- Park the vehicle on the central support
kickstand, with the front wheel off the
ground.

- Have someone hold the vehicle by keep­ing the handlebar in its driving position.

-

A second operator can now loosen the
screw (1) that blocks the wheel pin and
unscrew the pin (2).

- Hold the front wheel and manually slide
out the wheel pin (2).

WARNING

Mark the spacers and keep them apart
so as not to invert their positions when
reassembling the wheel.

NOTE: Remove the wheel, carefully sliding

the disk from the brake fork.

Remove the wheel by sliding it forward.

WARNING

Do not activate the front brake after
removing the wheel, otherwise the
fork pistons can leave their seats and

cause braking uid to leak.

If this happens, contact a VENT Deal­er.

Reassembling the front wheel

- Have someone hold the vehicle by
keeping the handlebar in its driving po­sition.

- Moderately grease the outer seats of
the wheel hub.

- A second operator should position the
wheel beneath the parts of the fork, in­serting the brake disk into the fork.

- Use grease on the wheel pin and slide
it completely with the spacer (3) into
the wheel hub (left side) and the spac­er (4) (right side).

- Tighten the wheel pin (2).

Wheel pin torque: 80 Nm (8 kg/m).

- Remove the central kickstand.

- With the front brake lever activated,
press repeatedly on to the handlebar,
causing the swingarm to dip.

This will allow the swingarm parts to

Brake uid level check

DANGER

Unexpected variations in the brake lever
play or elastic resistance on the brake
lever are caused by issues in the hy­draulic system.
If normal inspections cannot be carried
out, of if you are in doubt regarding the
perfect functioning of the braking sys­tem, contact a VENT Dealer, which will
be ready to provide you with accurate,
friendly service.

DANGER

Be particularly sure that the brake disk
is not greasy or oily, especially after car­rying out maintenance or inspections.
Make sure the brake tube is not twisted,

worn or cracked, cut or ssured in any

way.

NOTE: As the friction linings get worn, the

level of uid inside the reservoir diminishes,

to automatically compensate the wearing.

Brake lining check

- Park the vehicle on its kickstand.

NOTE: The brake fork comes with two
brake linings.

Visually inspect the area between brake
fork and linings, as follows:

- From above and from the front, for the
front brake fork (1);

- From above and from the back, for the
rear brake fork (2).

WARNING

If the friction material is worn beyond
acceptable limits, the metal support of
the lining might come into contact with
the disk, resulting in a metallic noise
and the formation of sparks against
the fork. The braking effectiveness, the
safety and the integrity of the disk would
therefore be compromised.

- If the thickness of the friction material (A)
(even if considering only one lining, ei­ther front or back) drops to about 1.5 mm
(or even if only one of the wearing indica­tors is no longer visible), it is necessary
to replace both linings.

DANGER

If this happens, contact a VENT Dealer.

Cooling uid level check

DANGER

While the engine is warm, the cooling

uid is under pressure and at a high

temperature.
Risk of burns on the skin and damage

It is advisable to periodically wash the ve­hicle, to maintain its components in good
conditions.

WARNING

Using in the following conditions re­quires more frequent washing, to pro­tect its components:

- Seaside areas or places with a hot, damp
climate, where humidity and saltiness
are above average.

- Roads or areas where salt or chemicals
are used as anti-freeze.

- Roads or areas with the presence of in­dustrial dust or asphalt spots.

52 use and maintenance manual

- Sports and off-road use.

- When the body of the vehicle is spotted
with dead insects, bird droppings etc.

WARNING

Avoid parking or lounging beneath
plants or trees.

During some seasons, certain plants
and trees drop or release residues, res­in, fruits or leaves containing substances
that can damage the vehicle (especially
its body).

Washing rules

WARNING

Do not wash the vehicle under the sun,
especially during summer, while the
body of the vehicle is still hot. If the de­tergent dries on its surface before it is
rinsed away, the painting may be dam­aged.

To clean the plastic parts of the vehi­cle, do not use liquids at temperatures
above 40° C.

Do not direct air or water at high pres­sure or steam jets on the following
parts:

- Wheel hubs;

- Commands on the left and right sides of
the handlebar;

- Bearings;

- Pumps and brake reservoirs;

- Instruments and indicators;

- Opening of the silencer or the exhaust;

- Steering lock;

- Radiatoraps;

- Fuel cap and any other caps;

- Headlights;

- Electrical connections;

- Stickers.

WARNING

Do not use alcohol, benzenes or sol­vents to clean the rubber or plastic parts
of the seat. Use only water
and a gentle soap.

NOTE: To clean ONLY the outer parts of

the engine, use a degreasing detergent
suitable for motorcycles, brushes and
cloths.

WARNING

Using high-pressure water jets can ruin
parts of the vehicle.

-

Use a low-pressure water jet to wet
the vehicle and, in particular, its soiled
parts.

- Use a soft cloth to rub all parts of the ve­hicle.

VENT 125 Baja + Baja RR / VENT 125 Derapage + Derapage RR

- Use a low-pressure water jet to rinse the
vehicle.

- Dry the vehicle with clean shammy leath­er.

STORAGE

Follow the precautions below to avoid the
effects deriving from not using the vehicle.

WARNING

Whenever a tyre remains in place for too
long resting on the ground, its proper­ties are altered.

DANGER

Washing the vehicle can reduce braking

efciency.

- Dry the disks, then carefully and repeat­edly test the brakes.

- Check all brake functions, referring to the

specicparagraph.

Polishing

WARNING

Only after accurately cleaning the vehi­cle should you proceed to polishing it
with silicone waxes.

Abrasive pastes ruin opaque paints.

DANGER

Never apply protective waxes on the
seat, as this would make it slippery and
therefore dangerous.

- Completely empty the fuel tank and the
carburettor.

- Remove the spark plug.

- Pour a teaspoon (about 5-10 cm3) of
two-stroke engine oil into the cylinder,
through the spark plug seat.

NOTE: Place a clean cloth on the cylinder,
near the spark plug seat, to protect against
oil splashes.

- Work on the start lever a few times, to
uniformly distribute the oil poured into the
cylinder.

- Reassemble the spark plug.

- Remove the battery.

- Wash and dry the vehicle.

- Apply was on the painted surfaces.

- Check tyre pressure.

- Park the vehicle in a non-heated place,
free of dampness, protected against sun­light and with as little temperature varia­tion as possible.

- Wrap a plastic bag around the exhaust
outlet or silencer to keep humidity or dirt
from entering.

- Place the vehicle on a support so that
both tyres are lifted off the ground.

WARNING

Protecting the vehicle from dust will
make vehicle parts last longer and facil­itate washing when the vehicle is to be
used again.
Avoid using plastic or waterproof mate­rials which might cause humidity to ac­cumulate, with consequent deterioration
of the parts.

- Cover the vehicle with a tarpaulin (made
of cotton, wool or another transpiring
mateiral) large enough to fully cover the
vehicle, without touching the ground.

When you decide to use the vehicle again:

- Uncover and wash the vehicle.

- Fill its fuel tank.

- Check its functions.

DANGER

Ride the vehicle for a few kilometres at
a moderate speed, in an area away from

heavy trafc.
