2. Before Riding
This manual describes the correct usage of this scooter including safety riding, simple inspection
methods, etc.
For a more comfortable and safety riding, please read this manual carefully.
For your benefit, please ask your SYM dealer to read the manual and operate carefully the
following:
‧Correct use of the scooter.
‧Pre-delivery inspection and maintenance.
Thank you very much for your patronage
In order to maximize your scooter’s performance, a periodical inspection and maintenance
should be completely carried out.
We recommend that after riding your new scooter for the first 300 kilometers, you should
take your scooter to the original dealer for an initial inspection, and to have your scooter
inspected periodically every 1000 kilometers thereafter.
In case the scooter’s specifications and construction are modified and different from the
photos and diagrams on the owner’s manual / catalogues, the specifications and construction
of the actual scooter shall prevail.
3. Safe Riding
When driving, it is very important to be relaxed, clothe properly, follow traffic regulations, do not
rush, and always drive carefully.
Usually, most people would ride their newly bought scooters very carefully, but after they became
familiar with their scooters, they tend to become reckless, which may result in an accident.
To remind you:
Please wear a safety helmet.
Do not use cellphone during riding.
Observe the speed limit.
Perform periodical maintenance and
inspection.
WARNING
！！
For both rider and passenger, get on the scooter from the left side. Passenger should keep
both feet on the footrest to avoid getting burned by exhaust pipe.
Recover footrest when not in use to secure pedestrian’s safety.
After running, the exhaust pipe is very hot, select a suitable location to park your scooter to
avoid others getting burned by the exhaust pipe.
High temperature！
Do not touch
！

4. Driving
Rider’s posture will greatly affect riding safety. Always keep your body’s gravity in the center of
the saddle, if your body’s gravity is on the rear part of saddle, the front wheel load will be
reduced, and this will cause the steering handle shaking. It is dangerous to ride a scooter with
an unstable handle.
Turning
•It will be much easier to make a turn if rider inclines his body inward when turning. On the
other hand, the rider will feel unstable if his body and the scooter do not incline.
Key point for turning:
①Decelerate before turning.
②Keep steady speed when turning.
③Accelerate properly when exiting turn.
④After exiting turn, make sure road safety then
reaccelerate.
Braking
•Apply both front and rear brake when
braking. Avoid hard/sudden braking and
keep vehicle and brake force steady.
Do not lock the brake. On well-paved road,
the front brake should be applied a bit more
than the rear. The brake force should be
adjusted according to the road condition.
Apply less front brake force on worse
road condition.

•The scooter is hard to control on a bumpy, unleveled, unpaved road, try to know the road
conditions in advance, slow down and use your shoulder’s force to control the handle.
Caution
•Do not place flammable materials such as rags between the body side cover and
engine to avoid components damaging by fire.
•Do not load objects on areas not specified for loading to avoid damage.
•Overload may affect handlebar operation.
•The rider’s feeling on the handle is slightly different with a load or without a load.
Overload may cause the handle to swing and affects the riding safety.
•Modified scooter will affect its structure or performance, and cause poor engine
operation or exhaust noise, which will result in shortening the scooter’s service life. Do
not modify your scooter at will.
•Turn off main switch and then turn on to restart the engine, when the vehicle falls down
and goes off.
To remind you:
•Wear a helmet when riding.
•Be sure to inspect your scooter before every ride
•Keep safety distance when riding.
•Decelerate when crossing intersection.
•Yield to moving pedestrians and vehicles.
•Do not modify your scooter at will.
•Turn on headlight in morning and at dawn.
•Do not drink and drive.
•Do not use cellphone when riding.
5. Use Genuine Spare Parts
In order to maintain the scooter’s best performance, each part’s quality, material, and
machined precision conform with the design requirements. “SYM Genuine Spare Parts” are
made from the same high quality materials used for the original scooter. No parts would be
sold to the market until they could meet the designed specifications through sophisticated
engineering and stringent quality control. Therefore, it is necessary to purchase “SYM
Genuine Spare Parts” from “SYM Authorized Dealers or Franchised Dealers” when replacing
spare parts. If you buy cheap, or fake substitute parts from the market, no guarantee can be
provided either for the quality or durability. Also, it may result in unexpected troubles and
lowering the scooter’s performance.
