MOTORCYCLE SAFE RIDING
AWARR'ING
Motorcycle riding requires special efforts onyour part to ensure your safety. Know these requirements below before you ride.
AFE RIDING RULES
.Always make a pre - ride inspection before you start the engine. You may prevent accident or equipment darnage.
2.Many accidents involve inexperienced riders. Most countries require a special motorcycle riding test or license. Make sure you are qualified before you
ride. NEVER lend your motorcycle to an inexperienced rider.
3.Many automobile/motorcycle accidents happen because the automobile driver does not " see " the motorcyclist.
Make yourself conspicuous to help avoid the accident that wasn't your fault:
.Wear bright or reflective clothing.
.Don't ride in another motorist's " blind spot " .
4.0bey all national and local laws and regulations
Excesswe speed is a factor in many accidents Obey the speed hmits, and NFVER travel faster than cond~t~onswarrant
Signal before you make a turn or lane change to draw other motorists' attention.
5.Don1tlet other motorists surprise you.
Use extra caution at intersections, parking lot entrances and exits, and always remember toride with both hands and keep both feet on the rider footrests.
6.kdingin wet days, brake distance should be two times that in dry days.
PROTECTIVE CLOTHS
1.Most motorcycle accident fatalities are due to head injuries. ALWAYS wear a helmet. You should also wear a face shield and protective clothing.
2.The exhaust system becomes hot during operation, and it remains hot for a while after stopping the engine. Be careful not to touch the exhaust system
while it is hot. Wear clothing that hllycovers your legs.
3.Donot wear loose clothing that could catch on the control levers, kick - starter, footrests or wheels.
REFITTING
AWARNING
Refitting of the motorcycle,or removal of original parts, maymake the vehicle unsafe or illegal. Obey all national and local equipmentregulations.

LOADING AND ACCESSORIES
AWARNING
To prevent an accident, take extreme care when adding accessories and
cargo and riding with them. Addition of accessories and cargo may re
-
duce a motorcycle's stability, performance and safe operating speed.
Remember these performances may be reduced by installation of the
accessories not produced by the company, improper loading, worn tyre
and overall motorcycle conditions, poor road or weather conditions.
These general guidelines may help you decide whether or how to equip
your motorcycle, and how to load it safely.
Loading
The maxlmum load weight of the motorcycle
IS 150kg
1.Keep calgo and accessoly weight low and close to the center of the
motolcycle Load welght equally on both sides to minimize imbalance
As welght 1s located further fiom the motorcycle's center of gravity, han
-
dling 1s proportionally affected.
2 Adjust tyre pressure and rear shock absorber to suit load weight and nding
conditions
3 Vehicle handling and stability can be adversely affected by loose cargo
Recheck cargo security and accessory mounts frequently
4 Do not attach large or heavy items (such as a sleeping bag or tent) to the
handlebars, fork, or fender. Unstable handling or slow steering response
may produce.
Accessories
Genurne accessories of the company have been specifically designed and
testedon the motorcycle.Because thefactory cannot test all other accessorres,
you are personally responsible for proper selection, installation, and use of
accessories not produced by the company Always follow the gurdelines
Ilghts, reduce ground clearance and banking angle, or lrmrt suspensron
travel, steernlg tiavel or control operation
2 Large fork - mounted farrings or windshields, or pooily designed ol rm-
properly mounted farrings can produce aerodynamic forces that cause
unstable handling Do not install fairings that decrease cooling air flow-
Ing to the englne
3 Accessories may increase the time that hands or feet operate controls,
resultrng in increased reaction time in an emergency
4 Do not add electrical equipment that will exceed the motorcycle's electn-
calsystem capacity
5 This motorcycle was not designed to pull a sldecar or trailer Handling
may be seriously impaired if so equipped

Lubrication
1 Use engine oil or a connnercially prepared drive chain lubricants in prefer-
i ence to motor oil or other lubricants. Saturate each chain link joint so that
the lubricant penetrates between the link plates, pins, bushings, and rollers.
Removal and Cleaning
When the drive chain becomes dirty, it should be removed and cleaned
i prior to lubrication.

4.Lubricate the drive chain.
5.Pass the chain over the sprockets and join the ends of the chain with the
master link. For ease of assembly, hold the chain ends against adjacent
rear sprocket teeth while inserting the master link.
AWARNING
Thechain clip should be so fitted to make sure that the closed end of the
clip faces the driving direction of wheel.

As the brake pads wear, brake fluid level drops. There is no adjustment to
perform, but fluid level and pad wear must be inspected periodically. If the
brake lever free play becomes excessive and the brake pads are not worn
beyond depth, there is probably air in the brake system and it must be bled.
