Introduction

You are now the owner of a modern motorcycle which will give you and your children much pleasure with maximum safety, provided
you look after and maintain the bike in good order. The manual supplied with your new motorcycle provides important information
concerning the handling and maintenance of the bike. At the time of publishing, it included the latest technical details for this series.
However, there may be minor differences due to constant developments in the construction of the motorcycles. The instructions
for use are an important element of the motorcycle and, in the event of resale, should be handed over to the new owner.

We would stress that all maintenance work to the chassis and engine should be carried out by specialised GAS GAS workshops.
In the event that such maintenance is required while competing with the bike, the work should be carried out by a qualified
mechanic.

Please follow the recommended running-in times as well as the inspection and maintenance intervals given. Strict adherence to
these time periods will have a direct affect on the working life of the motorcycle. In all cases maintenance services should be
carried out by a specialised GAS GAS workshop to ensure the bike remains under guarantee.

For your child’s safety, only use GAS GAS approved spare parts and accessories. GAS GAS will not accept responsibility for any
demage caused by the use of other parts.

Please note that as parents you should be aware that the safety of your children depends upon you finding a safe location for
the use of the motorcycle which should also be maintained in perfect technical order. Naturally, the motorcycle entails the possibility
of risk, as with all vehicles, and therefore you should ensure that all basic precautionary measures are observed. To do so, follow
the important instructions given to parents to ensure safe driving of the motorcycle.

Riding your motorcycle off-road is a marvellous sport which we hope you and your children will enjoy to the full. Nevertheless, it
can be a source of problems for the environment and of conflict with other people. Responsible behaviour when using your
motorcycle helps to prevent these problems and conflicts. To guarantee the future of motorcycling, please ensure that you and
your children use your motorcycle in accordance with the law, behave responsibly towards the environment and respect the rights
of others.

In conclusion we trust you and your children enjoy your motorcycle and always have a good journey.

production of a particular model without prior warning.

-8-

Caution!

The MC 65 motorcycle is designed for use Off-Road and
by only one person at a time. The use of this motorcycle
on public highways is prohibited.

The motorcycle is designed for use by children between
8 and 12 years of age with a maximum body weight of
50 kg and a maximum height of 160 cm.

- Before using the motorcycle ensure the child is equipped
with suitable protective clothing. Protective clothing
includes the helmet, goggles, protective gear for the trunk,
arms and legs, gloves and boots.

- Adjust the clutch and brake levers to the size of the
child's hand (with gloves).

- Adjust the basic position of the brake pedal to the child’s
position when seated.

- Before starting the cycle for the first time explain all the
manoeuvres to your child and ensure that he/she has
fully understood these. Go over the user manual step by
step with your child, carefully explaining the instructions
concerning dangers, and in particular, those which are
shown as warning of the risk of accident.

- Explain to your child about: driving techniques, falls,

and the effect of the movement of body weight on the
behaviour of the vehicle, etc.

- Before starting the cycle for the first time, check whether
the basic adjustment of the fork and shock absorber has
been adjusted to the body weight of the child.

- Each time you start the cycle, first check the working of
all the components (see section – Checks each time you
start the motorcycle) and teach the child how to make
these checks him/herself.

- If you are also riding a motorcycle adjust your speed to
that of your child and not vice-versa.

- The child should understand that the instructions or
signs given by you, or other person in charge, must be
followed to the letter.

- The child should be physically able to ride a motorcycle.
He/she should at least know how to ride a bicycle. The child
should be strong enough to lift the motorcycle after a fall.

- Do not expect too much of the child. Give him/her
sufficient time to become familiar with the motorcycle and
to improve his/her driving technique. The child should not
take part in competitions until his/her physical condition,
driving technique and motivation meet requirements.

Important instructions to parents to ensure the safe driving of the motorcycle

-9-

- Explain to the child that he/she should only drive at a
speed appropriate to the general conditions; otherwise,
he/she may fall and be seriously injured. Children are
often not aware of or do not recognise dangers. In
particular, speed should be reduced on unknown tracks.

- Never allow the child to use the motorcycle unsupervised.
An adult should always be present.
If you are out riding together, always tell someone where
and for how long you are going. This will allow help to be
obtained more quickly in the event of problems.

-10-

Instructions for starting the cycle the first time

- Check that the work detailed in “Checks each time you
start the motorcycle” has been carried out by your
representative.

- Carry out the preliminary driving trials with your child,
preferably in a field or garden to prevent injury in the
event that the child falls. The available area should, of
course, be large enough to allow different driving
manoeuvres. Take care to avoid collisions with other
drivers.

- To allow your child to become accustomed to the brake
lever action, the motorcycle should be pushed during the
preliminary trials. Do not start the engine until the child
is correctly able to control the brake lever.

- Initially, the child should be between two people who
help him/her to stop the motorcycle. Explain the procedure
for stopping alone to your child.

- To improve driving techniques, the child should also try
to walk as slowly as possible while straddling the
motorcycle. Position obstacles which the child should try
to avoid, etc.

- Follow the instructions for running-in.

Running-in period

Care of the engine during the first hours of use is vital for
obtaining the best from your motorcycle.
Therefore, we recommend:

- Keeping strictly to the ratios of oil and petrol shown,
using 100% synthetic oil – see the section “Fuel – Petrol/oil
mixture”, page 16.

- In the first hour of use, keep the engine at a moderate
turnover speed (never go to maximum turnover).

- Constantly change the speed, by opening and closing
the throttle alternately.

Caution!

- Only GAS GAS approved accessories should be used.

- The front and rear wheels should be fitted with tyres of
the same profile. Only approved tyres should be used.

- Replace the helmet visor or the goggle lenses if
scratched.

- Never leave the motorcycle with the engine running.
Remember that excessive noise may bother other people.

-11-

Checks each time you start the motorcycle

The motorcycle should be in excellent
technical condition while driving. For safety reasons,
a general check of the motorcycle should be made
each time you start the motorcycle. The following
checks should be carried out:

1 Gearbox oil

Low levels of gearbox oil result in premature wear
and the consequent damage to gears and gearbox
parts.

2 Petrol

Check the level of petrol in the tank. When the petrol
cap is closed, check that the tank vent hose is not
blocked.

3 Chain

A loose chain may come off the sprockets; a very
tight chain may break. A chain which has not been
adequately greased will result in excess wear of the
chain and sprocket.

4 Brakes

Check the level of brake fluid and that the brakes
work correctly. The tanks have been designed so

that the fluid does not require topping up even when
the brake pads are worn. If the level falls below the
minimum level, this indicates a fault in the brake
system or that the brake pads are totally worn. Have
the brakes checked at a specialised GAS GAS
workshop as the brakes may be faulty. Check the
condition of the brake line. Check the play of the
brake lever and brake pedal.

5 Tyres

Check that the tyres are in good condition. Tyres
with cuts or bulges should be replaced. Check the
tyre pressures. Incorrect air pressure affects driving
and may damage the tyres.

Caution!

If the resistance of the hand or foot brake lever
appears spongy, there is a fault in the brake system.
Have the brake system checked by a GAS GAS
dealer before using the motorcycle.

necessary, remove and dry the spark plug.

3- When the engine starts again, re-open the fuel tap.

Starting when the engine is cold (Cont.)

Caution!

To prevent injury when starting the motorcycle, boots
should be worn. Your foot may slip off the starter pedal
or the engine may kickback if the kick was not hard
enough.
Do not start or leave the engine idling in closed spaces.
Exhaust fumes are highly toxic and may result in loss
of consciousness or even loss of life. When the engine
is running, ensure that there is always adequate
ventilation.

Warning!

Driving the motorcycle while the engine is cold is not
recommended as the piston heats up more quickly
than the water cooled cylinder. Allow the engine to
warm up while idling or driving at low speeds.

Starting when the engine is warm

1- Open the fuel tap.

2- Place the gear in neutral.

3- Kick the starter pedal vigorously without opening
the accelerator.

-15-



Setting off

Pull on the clutch lever, engage first gear
and slowly release the clutch lever while

also accelerating.

Caution!

Always remove the stand before your child starts to
ride the motorcycle.

Changing gears, driving

First gear is the gear used to set off.
Conditions permitting (traffic, slope, etc), a higher
gear may be engaged. For this, close the throttle, pull
on the clutch lever, engage the next gear, release the
clutch lever and accelerate. When the choke is used,
make sure that it is pushed back once the engine is
warm.
When reducing gear, use the brake if necessary and
close the throttle grip at the same time. Pull on the
clutch lever and drop down to the next gear. Slowly
release the clutch lever and accelerate or reduce gear
again.

Caution!

After a fall with the motorcycle, all the functions should
be checked before starting the bike again.
A damaged lever should always be replaced. Never
repair the lever as this will result in loss of stability.

Warning!

A high engine speed when the engine is cold will have
a negative effect on the engine life. It is better to warm
the engine at medium speed for several kilometres,
and never reduce gear with the throttle fully open, if
the engine races, this may cause damage. In addition,
this may cause the rear wheel to lock, with the resultant
loss of control of the motorcycle.
If, during long descents, the engine is working without
accelerating, open and shut the throttle quickly from
time to time to ensure that the lubricant-petrol mixture
reaches the engine.

In the event of an unusual noise or vibration while
driving the motorcycle, stop immediately, switch off
the engine and contact a GAS GAS dealer.

-16-

Fuel – Petrol/oil mixture

The motorcycle is fitted with a two-stroke

internal combustion engine. This type of engine requires
a mixture of petrol and oil.

To ensure the correct working of the engine, the following
are recommended:

- Use high quality petrol, with an octane rating equal to
or above 90 (RON +MON)/2 or 98 (RON).

- Use 100% synthetic oil.

Warning!

- If the recommended oil is not available, use semi­synthetic oil.

- Do not mix different oil-types.
Mixture ratio: oil, 2,5% of petrol volume (40 parts petrol
to every 1 part oil).

Note: we recommend first preparing the mixture in a
suitable container and then filling the fuel tank.

Fuel tank

This has a rapid access cap (A) and a vent
hose (B) to allow gases produced in the tank to
escape.

- Turn the cap to the left to open.

Warning!

Regularly check the cap seal and vent hose to ensure
they are leak proof. Risk of spillage.

Fuel

Unleaded Super, 95 octane, mixed with two-

stroke oils. Mixture ration 1:40.

Caution!

Petrol is highly inflammable and toxic. Employ extreme
caution when handling petrol. Do not refuel in the
vicinity of naked flames or lit cigarettes. Always switch
off the engine before refuelling. Take care not to spill
petrol on the engine or exhaust pipe while these are
hot. In the event of spillage, quickly wipe off with a
cloth. In the event of contact with eyes or if swallowed,
seek specialist advice immediately.

Warning!

Only use super (95 octane) petrol mixed with high
quality two-stroke engine oil. Other types of petrol
may damage the engine.
Only use recognised brands of oil.
Lack of oil may result in the premature wear of the
piston. Too much oil causes excess fumes and
greasing of the spark plug. Petrol increases in volume
with temperature. Do not fill the tank to the limit.

Transmission oil – Checking the level

If the motorcycle has been used recently,
wait a few minutes before checking the level.

Note: the motorcycle should be perpendicular to the
ground.

Warning!

Place a suitable recipient under the engine to collect
possible oil spillage. - Remove the oil level screw (A).

The level is correct if it reaches the lower edge of the
oil level hole (A).
If the level is lower then more oil must be added.

Cleaning

Clean the motorcycle regularly.
We recommend using warm water with ordinary
detergent and a sponge. More resistant dirt may be
removed with a gentle jet of water.

Warning!

Never clean the motorcycle with a high pressure
cleaner or strong jet of water. The water may enter
electrical components, bearings, carburettor, etc.
resulting in their premature wear.

- Use ordinary household detergent for cleaning the
motorcycle. For more resistant dirt remove with a
brush.

- To prevent water penetration, cover the exhaust pipe
before washing the cycle.

- After rinsing, dry the motorcycle with compressed air
and a cloth. Then go for a short ride on the motorcycle
to allow the engine to reach its normal operating
temperature and also activate the brakes. This ensures
total evaporation of any water from the more
inaccessible points.

- Remove the protective rubber covers on the
controls to allow any water to evaporate from within.

- When the motorcycle has cooled, moving parts and

bearings should be greased. Lubricate the chain with
special spray.

- To prevent faults in the electrical system use a
moisture-displacing spray on the short-circuit switch.

CLEANING AND STORAGE

-30-

Storage

If the motorcycle is not going to be used for

a long period of time, the following should be observed:

- Thoroughly clean the motorcycle (see chapter:
CLEANING).

- The gearbox oil should be changed (the used oil
contains rusty particles).

- Check the antifreeze and the coolant level.

- Allow the engine to warm up again, close the fuel tap
and leave the engine to stop on its own. This prevents
rust on the carburettor jets due to old fuel.

- Remove the spark plug and pour approx. 5 cc of
engine oil through the cylinder opening. Activate the
starter pedal approx. 10 times to allow the oil to cover
the walls of the cylinder and reassemble the spark
plug.

- Drain the fuel tank into a suitable container.

- Check the tyre pressures.

- Lubricate the bearings of levers, foot rests etc. and
the chain.

- Adjust the rear suspension.

- The storage area should be dry and not
subject to large temperature fluctuations.

- Cover the motorcycle with breathable canvas or
canopy. Do not use impermeable fabric as this will
trap the damp and cause rust.

Warning!

The engine of a motorbike can be damaged if used for
short periods when cold. Because the engine does
not reach its optimum operating temperature, steam
generated during combustion condenses, leading to
rusting of the exhaust.

Starting after storage

- Fill the tank with new petrol.

- Carry out the checks for each time you start the
motorcycle (see instructions for driving)

- Make a short trial ride.

Warning!

Before storing the motorcycle at the end of the season,
check the working and wear of all the parts. If technical
service, repair or modification work is required, these
should be carried out now during the off-season). This
avoids long waiting times at the workshops at the start
of the season.

Warranty terms of the manufacturer GASGAS Motos, S.A.

The company GAS GAS MOTOS, S.A. (hereafter referred to as “GG”), with this present document guarantees the
consumer, the purchaser of a vehicle manufactured by GG, that both the materials and the manufacturing are free
of defects in accordance with the highest standards of quality. Consequently, GG with this document guarantees
the consumer (hereafter referred to as the “purchaser”), in accordance with the conditions set out below, the repair,
free of charge, of any defect in materials or that might result from faulty manufacture that is detected in a new
motorcycle within the period covered by this Warranty and with no limit on the number of kilometres covered or hours
of use.

Warranty Period

The period covered by this Warranty will begin on the day of delivery of the vehicle to the purchaser by a GG
authorised dealer, or in the case of demonstration models, on the date in which the vehicle is used for the first time.

the European Community, the Warranty Period will be determined by the existing regulations in those countries.
Nevertheless, should the fault appear during the first six months after the delivery of the motorcycle, it will be presumed
that the said fault existed at the time of delivery; from the end of the sixth month onwards, the purchaser must
demonstrate that the unwarranted fault existed at the moment of delivery. During the first six months subsequent
to the delivery of the repaired vehicle, the seller will be responsible for any unwarranted faults arising out of the
repair.
Any defects detected in the product must be brought to the attention of a GG authorised dealer within the Warranty
Period. If the last day of this period is a Sunday or an official holiday, the Warranty period will be extended such that
the last day of the period covered will be the first working day after the Sunday or official holiday.

to whom the making good of the defects has been entrusted, is not authorised to make any declarations that are binding
on GG.

to demand the return of the parts which are the object of a claim under Warranty, or to arrange an inspection of the defect

service rendered free of charge, are excluded from the effects of this present warranty. The Warranty on parts replaced
within the Warranty Period will end at the expiry date for the Warranty Period of the product concerned.

3.- Should it prove to be the case that a defect can not be repaired, the purchaser guaranteed shall have the right to the
cancellation of the contract (payment of compensation) or a partial refund of the purchase price (discount), instead of
