Due to oil tank design, road condition, driving status and so on, the performance of fuel indicator is not always appeared in linear way. Some types has special consideration that main and secondary fuel tank is installed, but the sensor is set in main tank, causing the indicator needle standing still before certain mileage.

So, take the fuel indicator as a reference, then calculate the fuel quantity consumed after each refueling, also keep the indicator needle above the low fuel warning line, thus to keep the motorcycle from out of fuel.

The Combined Brake System (CBS) is a brand-new way of scooter braking solely developed by SYM. The tradition way of scooter braking is to pull the brake lever through both hands.

Because the throttle and front wheel brake are both operated by right hand, thus insufficient braking force might be applied during emergency, even cause slip and fall at rear wheel.

The CBS system take a joint way to apply braking, when driver pull the brake lever, brakes of both wheels would be activated at the same time, to sustain the stability during emergency braking.

The structure of CBS system is rather complicated, if any abnormal situation of CBS system appeared, please return to the service center as soon as possible. The adjustments must be performed by technician, any unprofessional adjustments may be extremely dangerous and is strictly prohibited.

The filtration efficiency of air cleaner is crucial to it's performance, efficiency and durability of an engine, so the manufacturer would list the air cleaner as a periodical check or exchange item.

The frequency to check air cleaner should be increased if operated in dusty enviroment, to prevent engine break down.

The air cleaner should be exchanged every 3000~5000km under normal operation.

If the vehicle operates in dusty environment, the checking frequency should be increased, and replace air cleaner element if necessary to prevent engine failure.

The manuals shows significant notices to increase checking frequency for inspection or clean/exchange air cleaner element depends on the operating environment.

1. Brake pads are too hard.
2. Caliper deformed.
3. Cushion and caliper are not parallel.
4. Morning effect. If disk brake left without using for a certain time, the pad would absorb the mist,  causing harshness when braking. This situation would be eased after several times of use.
5. Something hard jammed the brake pad.

The ABS is an abbreviation of Anti-lock braking systems. It is an active safety braking system for vehicles features designed to help drivers retain steering control by preventing wheels from locking up during an episode of heavy braking.

ABS is designed to help prevent the wheel from locking up when hard brakes are applied while running straight. The ABS automatically regulates brake force. Intermittently gaining gripping force and braking force helps prevent wheel lock-up and allows stable steering control while stopping.
