cally and physically able to drive, focus-
ing particularly on physical fatigue and
drowsiness.
- Anothersignicantcauseofaccidentsis
driver’s inexperience. DO NOT entrust

- If the vehicle has been in an accident or
has been in a crash or fall, make sure the
command levers, the tubes, the cables,
the braking system, the wheels, the tyres
and all other parts are intact.
If the damage is persistent or if you are
uncertain of its conditions, take the car to
a VENT dealer, where the vehicle will be
tested and inspected.
Always report any case of malfunctioning
to make it easier for the technicians and/
or mechanics to solve the problem.
DANGER
Do not drive or allow anyone to drive the
vehicle if the damage it has suffered is
compromising its safety.
- Itisforbiddentocarryoutanymodica-
tion to the vehicle.

at the maximum level permitted, indicat-
ed in the relative paragraph “Cooling
uid level check”.
Exhaust fumes
DANGER
Exhaust fumes consist of carbon mon-
oxide, an extremely harmful substance
if inhaled.
Avoid starting the engine in closed spac-
es 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 bat-
tery, make sure there is sufcient air cir-
culation in the area.
SAFE DRIVING
This paragraph offers some suggestions for
driving/riding safely.
ACCELERATION. Accelerating and decel-
erating 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 ap-
plied 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 con-
sequences for themselves and for oth-
ers, as well as for the vehicle.
BRAKING IN ASCENT. Decelerate com-
pletely and use both brakes to keep the ve-
hicle in place.
Using motion force (using the accelerator)
to keep the vehicle in place causes anom-
alous overheating of the engine and of the
clutch.
Keeping the vehicle in place using only
physical strength may cause loss of bal-
ance and fall, with serious consequences
for yourself, for others and for the vehicle.

VENT 125 Baja + Baja RR / VENT 125 Derapage + Derapage RR
8use 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 brak-
ing. 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 materi-
al (brake linings or shoes) and consequent-
ly reduces brake effectiveness.
Combine the use of brakes and the com-
pression 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 ADHER-
ENCE 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
paintedover,metal slabs belonging tobuild-
ing sites along the road, may all be slippery
or otherwise jeopardise, even if only tempo-
rarily, vehicle stability, causing falls with se-
rious consequences for yourself, for others
and for the vehicle.
CHANGING LANES OR DIRECTION. Al-
ways activate the blinkers when changing
lanes or direction, and carry out the ma-
noeuvres with regularity.
Turn off the blinkers after use.
OVERTAKE CAREFULLY Whenever over-
taking 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 your-
self, for others and for the vehicle.
WARNING
Always follow the recommended indica-
tions 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 ve-
hicle 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, hand-
rails etc.
- The vehicle must always be parked on its
kickstand.

use and maintenance manual
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
Vehicle identication
Each VENT vehicle comes with a vehicle
identicationnumber(V.I.N.)
This vehicle displays its V.I.N.:
- On the chassis, on the steering head on
the right side (A);
- On the SUMMARY PLATE (B), located
on the right side of the chassis, near the
steering head.
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.
Engine identication
The engine number (C) is printed on the
base of the engine casing, on the left lower
side.
