not to touch the exhaust system since it is hot. Wear clothing that fully covers your legs.
3. Do not wear loose clothing that could catch on the control levers, kick-starter, footrests or wheels.
REFITTING
WARNING
Refitting of the motorcycle ,or removal of original parts may make the vehicle unsafe or illegal. Obey all national and
local equipment regulations.
ACCESSORIES
Genuine accessories by our Co. have been specifically designed and tested on the motorcycle. Because our Co. won’t
test and accessories manufactured by other company/factory, you are personally responsible for selection, installation, and
use of them. Always follow the guidelines below:
1. Carefully inspect the accessory to make sure that it does not obscure any lights, reduce ground clearance and banking
angel, or limit suspension travel, steering travel or control operation.
2. Accessories may increase the time that hands of feet operate controls, resulting in increased reaction time in an
emergency.
3. Do not add electrical equipment that will exceed the vehicle’s electrical system capacity.
Do not add device cooling the engine.

FUELANDFUELTANK
Fuel Selection
Fuel is a key factor in deciding the exhaust emissions amount from the engine, so selection of fuel must follow the rules
below.
Selected fuel must be unleaded or low-leaded gasoline with octane No.RQ-90 or higher.
The fuel tank capacity is 7.8L.
WARNING
●
Gasoline is extremely flammable and is explosive under certain conditions. Refuel in a well-ventilated area with the
engine stopped. Do not smoke or allow flames or sparks in the area where gasoline is stored or where the fuel tank is refueled.
●
Before refueling, make sure to filter fuel first.
Do not overfill the tank (there should be no fuel in the filler neck). After refueling, make sure the fuel tank cap is closed
securely.
●
Be careful not to spill fuel when refueling. Spilled fuel or fuel vapor may ignite. If any fuel is spilled, make sure the
area is dry before starting the engine.
●
Avoid repeated or prolonged contact with skin or breathing of vapor.
●
KEEP OUT OF REACH OF CHILDREN.

SPEED-LIMITINGDEVICE
Turn loose the lock nut and screw in the adjusting screw,
at last, tighten the locknut.
CAUTION
It’s better for inexperienced riders to set the top speed
lower so as to avoid accidents.
ENGINEOIL
The quality of the engine oil plays a vital role in decid-
ing the engine performance and service life.
Engine oil must be selected in accordance with the rules
below and other oils, are forbidden to be used.
②Adjusting screw ①Lock nut
Engine oil recommended: gasoline engine oil Class
SAE15W/40-SE or Class SE, SF, SC from API Service
Classification.
The vehicle has been filled with the engine oil Class
SAE15W/40-SE Class before being been delivered, and the
lubricant is only suitable at a temperature range from +40°C
to -10°C. If other motor oil is to be used instead, the alterna-
tive must be technically in every respect. Viscosity varies
with regions and temperatures, so the lubricant has to be
selected according to our recommendation. If the gasoline
engine oil Class ASE15W/40-SE can not be obtained when
in need, the gasoline engine oil No. HQB-10 (or No. HQB-6
in regions where the temperature is under -10°C ) is available.
Before replacing the lubricant, please drain the oil out
completely remaining in the crankcase, and clean the inside
by cleansing kerosene, then fill new one inside.

-12-
CAUTION
Running the engine with insufficient oil can cause seri-
ous damage to engine.
TYRES
Proper air pressure will provide maximum stability,
riding comfort and tyre life.
Check tyre pressure frequently and adjust if necessary.
Select the right replacement tyres in accordance with
the specifications shown in the table1.
NOTE
Tyre pressure should be checked before you ride while
the tyres are cold. Check the tyres for cuts, embedded nails,
or other sharp objects.
Check the rims for dents or deformation. See your dealer
for change of damaged tyres or punctured inner tubes.
WARNING
●
Do not attempt to patch a damaged tyre or inner
tube, otherwise wheel balance and tyre reliability may be
impaired.
●
Improper tyre inflation will cause abnormal tread
wear and create a safety hazard. The tyre pressure less than
the rated value may result in the tyre slipping on the ground,
or coming off from the rim, even the vehicle being out of
control.
●
Operation with excessively worn tyres is hazardous
and will adversely affect traction and handling.
●
The use of tyres other than those listed on the table
1 may adversely affect handling.

OPERATION GUIDE
PRE-RIDE INSPECTION
WARNING
If the Pre-ride Inspection is not performed, severe in-
jury to personnel or damage to equipment may occur.
Inspect your motorcycle every day before you ride it.
The items listed here will only take a few minutes to inspect,
and in the long run they can save time, expense, and possi-
bly your life.
1. Engine oil level-add engine oil if required. Check for
leads.
2. Fuel level-fill fuel tank when necessary. Check for
leaks.
3. Front and rear brakes-check operation and if
necessary, adjust free play.
4. Tyres-check condition and pressure.
5. Throttle operation-check for smooth opening and
full closing in all steering positions; check for throttle grip
free play and throttle cable in lubricating and connecting.
6. Fastener-check that all nuts, screws and bolts are
fixed securely.
7. Steering system-check for its smoothness and
reliability. Correct your dealer for assistance if you cannot
correct the problem.
STARTINGTHEENGINE
Always follow the proper starting procedure described
below.
WARNING
Never run the engine in an enclosed area. The exhaust
emissions contain poisonous carbon monoxide (CO) gas that
can cause loss of consciousness and lead to death.

☆Starting procedure by the starter button
1. Place the vehicle on a level ground and lock the rear
brake by depressing down the parking button.
2. Insert the ignition key switch and turn to (ON).
3. Set the emergency switch to “ON”.
4. Depress the starter button while rotate the throttle
grip slightly to start the engine. Release the starter button
once the engine starts.
NOTE
Do not use the electric starter for more than 5 seconds
at a time. Release the starter button for approximately 10
seconds before pressing it again.
5. When starting and warming up the engine, make sure
to maintain the throttle slightly open.
6. Before riding the vehicle, make sure that the engine
is well warmed up.

BREAKING-IN
Help assure your vehicle’s future reliability and performance bypaying extra attention to how you ride during the first
two-week riding.
During this period, avoid full-throttle riding and loading the engine heavily ;be sure to keep changing speed.
NOTE
After the breaking –in period, be sure to conduct maintenance according to the maintenance schedule so as to keep the
vehicle in a sound condition, which will extend the service, which will extend the service life of the engine obviously.
RIDING
Review Vehicle Safe Riding before you ride.
1. After the engine has been warmed up, the vehicle is ready for riding.
2. End braking state of the vehicle.
CAUTION
Riding with only one hand may cause the vehicle out of control.
3. Open the throttle gradually so the vehicle moves forward.
4. To slow down the vehicle, reduce the throttle while carry out braking. Coordinate the throttle with brakes for
smooth deceleration.
NOTE
Both the front and rear brakes should be used at the same time and should not be applied strongly enough to lock the
wheel, or braking effectiveness will be reduced and control of the vehicle be difficult.

-16-
PARKING
1. Close the throttle while apply the brakes to slow
down the vehicle until it stops.
2. Turn the ignition key to (OFF), and remove the key
once the engine stops.
3. press down the parking button at the left handlebar.
Apply the parking brake.
CHECKANDCHANGE OFENGINE OLL
Check of Engine Oil Level
Check the engine oil level each day before riding the
vehicle.

engine service life. Change the engine oil as specified in the
maintenance schedule.
1. Drain out the engine oil in the crankcase completely.
2. Clean the crankcase inside with cleaning lerosene.
3. Add specified engine oil about 0.8L.
