SAFE DRIVING

This paragraph offers some suggestions fordriving/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.

FACING AND RIDING A
CURVE. Do not ride into a curve at highspeed.
Do not underestimate the difficulty involvedin 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 orcontrol of the vehicle. If it is necessary to
use the brakes, do it with moderation andattention.
NEGOTIATING DESCENTS: Never ridethe vehicle with the engine off in descents.
Using only the brakes when riding down aslope 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 andwait 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
8

use and maintenance manual

50cc_EU5_MY20_4 lingue_07-2021.indd 8

necessary, proceed at moderate speed andavoid sudden manoeuvres; always brakewith caution so as to avoid losing control ofthe 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 slipperyor 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.
OVERTAKE CAREFULLY Whenever overtaking another vehicle or when you arebeing overtaken yourself, be particularly
attentive. Water splashes when the roadis wet and the slipstream caused by the
motion of large vehicles can cause loss ofcontrol of the vehicle and the possibility offalling, with serious consequences for yourself, for others and for the vehicle.
WARNING
Always follow the recommended indications when driving/riding.

PARKINGDANGER
Accidentally falling from the vehicle cancause:- Fuel leaking from the tank, resulting
in fire hazard;- Cooling fluid leaks;- Engine oil leaks;- Damages to people, things and the vehicle itself.
To avoid accidental falls with the vehicle,
choose a solid, flat terrain and an area ofsuitable 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 andprevent 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.

VENT 50 Baja + Baja RR / VENT 50 Derapage + Derapage RR

28/09/2021 14:29:26

DANGERThe 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.

Every request made to the dealer must be
accompanied by the V.I.N. of the vehicle inquestion, 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 theirrelative warning lights are on;- pull the front brake lever and press therear brake pedal; make sure the rearstop light turns on;- check the level of fuel, of the gearbox oil
and of the oil in the mixer;- Check the brake fluid level in its tank;- Check the cooling fluid 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.

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

- 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.

NOTE: If you are unable to rest both yourfeet on the ground on both sides of the bike,firm your right foot on the ground and keep
the left one ready to offer support.

Climbing on the bike
- With the bike on the side kickstand, thepilot must climb on the motorbike fromits left side, with both hands holding thehandlebar.
- Once the pilot is on the bike, lift the bike;the side kickstand will automatically lift
as well.

- The passenger must extract the rearfootrests and climb from the left sideof the bike, using the left footrest while
holding on to the pilot.

VENT 50 Baja + Baja RR / VENT 50 Derapage + Derapage RR

50cc_EU5_MY20_4 lingue_07-2021.indd 21

DANGER
Make sure the side kickstand is fully lifted.

use and maintenance manual

21

28/09/2021 14:29:38

Climbing off the bike- First of all, the passenger must climb off theleft side of the bike, using the left footrest.
- Once on the ground, the passenger mustpush the rear footrests back in.
- The pilot must keep his/her hands firm 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 kickstandand make sure the motorcycle is resting
its weight on it (for kickstand operations,please read the “Side kickstand” chapter).

Break-inBreaking in is crucial for the proper working
and duration of the engine.
The break-in means the first kilometrescovered.
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).
Rules for a good break-in
These rules are only suggestions to help therider break in the motorcycle properly. Failing to follow them may not result in immediate damage, but can have negative effects
on the performance of the engine and of thedifferent parts of the vehicle.
STRESS It is important to “stress” the engine and the other parts of the vehicle in an
appropriate manner. It is also important not
22

use and maintenance manual

50cc_EU5_MY20_4 lingue_07-2021.indd 22

to exceed and not to stress insufficiently; inboth 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 andmoderate hills, where the engine, the brakes
and the suspensions can alternate periods
under stress and periods with little or nostress 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 brakelinings 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 brakelever with more intensity. Avoid sudden, long
brakes.

Right rear view adjustment
DANGER
Never drive with the rear-view mirror rotated incorrectly.
Before moving off, always make it is in
the correct work 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 yoursitting position.
DANGER
The mirror must be adjusted with the
motorcycle at a standstill.

NOTE: The first 500 km (312 miles) are thethreshold of end of break-in, but only after
the first 1,000 km (625 miles) do the vehicle’s best performances occur.
WARNING
The 500-km break-in threshold (312 miles)
requires carrying out the maintenance
operations defined for this distance.

Brake fluid level check
DANGER
Unexpected variations in the brake leverplay or elastic resistance on the brakelever are caused by issues in the hydraulic system.
If normal inspections cannot be carriedout, of if you are in doubt regarding theperfect functioning of the braking system, contact a VENT Dealer, which will
be ready to provide you with accurate,friendly service.

MIN = minimum level (Half of the inspection hatch)- If the fluid is not at or above the MIN level
and the brake linings are not yet to be
replaced, fill up the reservoir.
DANGERFor brake fluid top-up, contact a VENT
dealer.

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 fissured in any
way.

DANGERFor brake fluid top-up, contact a VENT
dealer.

Brake lining check- Park the vehicle on its kickstand.
NOTE: The brake fork comes with two
brake linings.
Visually inspect the area between brakefork and linings, as follows:- From above and from the front, for thefront brake fork (1);- From above and from the back, for therear brake fork (2).
WARNING
If the friction material is worn beyond
acceptable limits, the metal support ofthe lining might come into contact withthe disk, resulting in a metallic noise
and the formation of sparks against
the fork. The braking effectiveness, thesafety 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 fluid level check
DANGER
While the engine is warm, the cooling
fluid is under pressure and at a hightemperature.
Risk of burns on the skin and damage
