protection in motorcycle riding. Therefore, be sure to wear a safety helmet
whenever you drive your motorcycle. Also wear a pair of proper protective
glasses and good quality gloves.
Be familiar with the vehicle
Understanding how your vehicle is built, maintained and the correct
functioning of all the key controls is vital to enjoying safe motorcycling . Be sure
to keep in mind that skill comes from practice. Train and practice in a safe traffic
free environment.
Understand what is a safe speed
Drive at all times at a speed which is consistant with the prevailing weather
conditions, road conditions and your skill level. Keep within safe parameters
when judging your speed.
Please note that on rainy days, the braking distance is two times as much
as that in fine weather. Keep away from any manhole cover, paint mark or oil
spillage to prevent skidding and always keep a safe distance with any vehicle in
front.
Wear correct dress
As well as a crash helmet, your motorcycle attire is important in
providing you with the safest possible experience. Always wear clothing
designed for motorcycling ( your dealer can advise).

Gear lever
The motorcycle is provided with a 5-speed gear transmission. The gear lever
connects to a ratchet mechanism in the transmission. After selecting a gear, the

Precaution
Do not fill the tank excessively. Never splash fuel onto a hot engine.
Overfilling the tank can result in fuel leaking from the filler cap if there is
expansion due to the machine being left in strong sunshine.
During refueling the engine must be turned off and the ignition
isolated. Smoking is strictly forbidden during fuel refilling.
