3.SAFE RIDING
It is very important to be relaxed and wear properly while riding, observe traffic regulations, do not rush,
always ride carefully and relaxed.
Usually, most people would ride their newly bought vehicle very carefully, but after they become familiar
with their vehicle, they tend to become reckless which may result in an accident.
To remind you：
Please wear a helmet, and properly tighten the helmet belt when riding.
Clothes with open or loose cuffs may be blown by wind and cause the cuffs caught on the steering
handlebar and thus affects riding safety. So put on clothes with tight sleeves.
Hold the steering handlebar by both hands when riding. Never ride with only one hand.
Observe the speed limit.
Wear suitable low-heel shoes.
Perform periodical maintenance and inspection in accordance with the schedule.
CAUTION：
Modified vehicle will affect its structure or performance, and cause poor engine operation or exhaust
noise, which will result in shorter vehicle service life.
Besides, modification is illegal and does not conform to the original design and specifications.
A modified vehicle will not be covered by warranty. Therefore, do not modify your vehicle at will.
Tire and rim modifications will make it unsafe to ride and may cause severe injury or death.

Keep your body such as shoulders, arms, palms, and waist relaxed and ride with the most comfortable
posture in order to react quickly when necessary.
Riding posture will greatly affect riding safety. Always keep your body’s gravity in the center of the
seat. If your body’s gravity is on the rear part of seat, the front wheel load will be reduced, and this
will cause the steering handlebar shaking. It is dangerous to ride a vehicle with an unstable
handlebar.
It will be much easier to make a turn when the rider inclines his body inward. On the contrary, the
rider will feel unstable if his body and the vehicle do not incline when making a turn.
The vehicle 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 handlebar.
Suggestion: Do not load unnecessary objects on the front floor panel; avoid affecting the riding
safety and the operation of steering handlebar.
CAUTION：
The rider’s feeling on the handlebar is slightly different with or without a load.
Overload may cause the handlebar to swing and affect the riding safety.
Therefore, do not overload your vehicle.
Overload will cause the vehicle become unstable and hard to control, it may cause serious damage to the
tires and rims; it may also change the center of gravity, which could result in an accident that could cause
injury or death. Do not exceed the maximum authorized load.
If equipped with USB charging function, do not use it in rainy days
4.USE GENUINE SPARE PARTS
To maintain the vehicle’s best performance, each part’s quality, material, and machined precision must
conform to the design requirements.
“SYM Genuine Spare Parts” are made from the same high quality materials used for the original vehicle.
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 the cheap or fake substitute parts from the market, neither quality nor durability will be
guaranteed.
Also, it may result in unexpected troubles and reduce the vehicle’s performance.
Always use SYM Genuine Spare Parts to ensure its long service life.
