1Security
The motorbike is a really particular vehicle, which gives incomparable sensations of power and freedom.
However, it is very important not to forget that the best motorbike has only two wheels, so that it can
not escape from physical laws.
As a consequence, the vehicle has to be maintained in the best work order. That is exactly the same for
the rider. SCORPA recommends you to respect the laws of the country where you are riding, not to ride
under the influence of alcohol or of drugs. To be in a great form, without extreme fatigue, can allow you
a safe driving and quick reflexes.
Riding motorbike implies that you wear sturdy bike clothes. The helmet, the clothes (of leather or of
reinforced synthetic materials), solid shoes (preferably bike boots) and gloves are essential for the rider.
Wearing such equipments must not lead to change of the way of riding, and the security instructions
must be respected.
2Description of the vehicle

3.2.3 Gearshift lever
The gearshift lever is situated on the left side of the bike, at left toes level, when the heel rests on the
left rest-foot. The use of the gearshift lever must be done only when the engine is released. That means
the clutch lever is pulled towards the handgrip. The gearshift lever allows choosing one of the 5 gears of
the gearbox.
3.2.4 Front brake lever
The front brake lever is situated on the right side of the handlebar. To operate the front brake, pull the
lever towards the handgrip.
Precautions in the handling of the brake levers.
The brake levers handling must be accompanied by high precautions. In fact, a wheel lock often means
the fall of the rider and its bike. That is one of the main reasons why the motorcyclists can fall. It is
recommended to pull the lever as progressively as possible.

3.2.5 Rear brake pedal
The rear brake pedal is situated on the right side of the bike, at the front of the right foot level, when
the heel rests on the right rest-foot. To operate the rear brake, push the pedal towards the ground.
Precautions in the rear brake handling
As told for the front brake lever, be careful not to operate too strongly the rear brake pedal. Otherwise it
can lead to the lock of the rear wheel and the fall of the rider.
3.2.6 Choke handling
As the engine is cold, it may need to have recourse to the choke, in order to make the air / fuel mixture
richer. Pull the control to open the choke and enrich the mixture. Push the control towards the ground to
close the choke and to impoverish the air / fuel mixture.

3.2.7 Antitheft lock
Locking the direction: insert the key in the lock and turn it a quarter of turn towards left. Push it and,
while maintaining it pushed, turn it a quarter of turn towards right. Withdraw the key, the direction is
locked.
Unlocking the direction: insert the key in the lock and turn it a quarter of turn towards left: the lock goes
up. Turn the key a quarter of turn towards right to withdraw the key and put it in your pocket.
WARNING
Do not let the key in the key while riding. Always withdraw it before starting using your bike.
3.3 Fuel tank
3.3.1 Fuel tank cap
B
A
Lock

12
To remove the cap from the fuel tank, turn it anticlockwise (in the direction A), until it can be taken
away. As soon as the cap is not screwed on the fuel tank, you can take it.
To put it back, turn the cap clockwise into the fuel tank (in the direction B).
When the tightening becomes harder, it is important to give one more effort, in order to be sure the fuel
cap is tightened enough.
WARNING
It is very important to check that the cap is tightened enough before starting the engine and riding the
bike.
3.3.2 Fuel
The recommended fuel is only lead-free high octane petrol. The highest capacity of the fuel tank is 2,0
litres and the reserve is 0,6 L.
WARNING: the use of another fuel than this recommended by the manufacturer can cause serious
deteriorations on the engine and on the exhaust system. SCORPA will not be responsible for any
problem in that case
Before each use, check that the quantity of fuel is sufficient. In case it is not, complete in the tank. The
filling up must absolutely not exceed the maximum level. Otherwise, the fuel contained in the tank could
easily flow along it.
WARNING
The fuel tank must not be too much filled. In fact, as the engine is very close, the overflowing would be
increased by the expansion due to the warmth.
The filling up has to be operated with a lot of precautions. There must not be fuel on the engine. This is
recommended not to fill the fuel tank near a flame or near a source of heat.
WARNING :
When a little amount of fuel overflows on the tank during the filling up, wipe it thanks to a sweet, soft
and dry duster, in order to avoid to damage plastic, polished and painted parts.

3.3.3 Fuel tap
Its aim is to control the flow of fuel from the fuel tank to the carburettor, as the rider wants it to be
regulated. This tap contains a filter, which role is to hold back the particles which could damage the
engine. This diagram shows the three different possible positions. The chosen one is pointed out thanks
to the drawn arrow.
There are three different positions :
OFF : The tap is off and the fuel is not able to flow to the carburettor. The tap must be on „off‟
when the engine does not run.
ON : the tap is running and the fuel can flow to the carburettor. The tap must be on „on‟ before
trying to start the engine and during the use of the bike.
RES (Reserve): when the fuel tank is almost empty and the fuel does not flow anymore, put the
tap on the position „res.‟. This system is expected to allow you to join the first filling station. Fill
up the fuel tank as soon as possible. When the tank is full, put back the tap on the position „on‟.
3.4 Side stand
sidestand

14
The side stand is fixed to the swinging arm on the right side of the bike. It automatically folds back as
soon as the bike is put vertical.
WARNING
During the fallback of the side stand, take care not to let one of your limbs near the mechanism and be
sure the third parties do so. That is the way to minimize the risks of plucking. However the stand
includes a protective rubber.
4Check before use
The owner is responsible for the condition of his vehicle. The bike may suffer damages during the use
and during the parking too (bad weather or acts of vandalism for example). The damaging of parts
which take part in the security can have very serious consequences. SCORPA recommends you to check
visually those sensitive spots. If necessary, a more detailed check is naturally advocated. In case you
have any doubt, do not hesitate to get in touch with your dealer.

5Instructions and advice before starting the bike
WARNING
Before using the SY-250FR 15thA, it is recommended to familiarise yourself with the engine and verify
all of the functional commands in a non-hazardous area. When in doubt, refer to the SY-250FR 15thA
manual and if need be your local dealer.
The engine never must be started in a closed area or room, even for a very short period of time. The
exhaust gases are very toxic. Some of them are colourless and odourless, but can cause very serious
suffocatins (even fatal).
5.1 Starting (cold engine)
Before you start the engine, you have to put the gearbox in neutral position for security reasons :
The gearbox is placed on neutral
If the bike is in gear, the clutch lever must be pulled and the side stand folded up.
1. Turn the tap towards to „ON‟ :
2. Pull the choke lever and release the accelerator handling :
3. Spread the kick-starter.
4. Place you right foot on it and step very violently on it towards to the ground.
5. If the engine does not start, operate the two last indications again.
6. As soon as the engine starts, release the first half of the choke lever.
7. When it is warm enough, release totally the choke lever.
NB : you can consider that the engine is warm enough when it accelerates well, even when the choke is
totally released.
WARNING: in order to improve the useful life of your vehicle, make sure the engine is not excessively
accelerated until it is warm enough !
